camera lens

The principle of lens coating: By forming thin film layers of different thicknesses on the surface of the lens, the reflection and interference of light between the thin film layers can make the phase of light of a specific wavelength destructively interfere, thereby reducing reflection. This way, the lens can more effectively pass through the light, reduce the loss and scattering of light, and improve the contrast and clarity of the image. Lens coating has the following benefits: 1.Improve light transmittance: Coating can reduce the reflection of the Camera lens surface, improve light transmittance, make the image brighter and clearer, and reduce light loss. 2.Suppressing light scattering: Coating can reduce the scattering phenomenon on the lens surface, avoid light interference inside the lens, and improve the contrast and detail clarity of the image. 3.Anti-scratch and anti-fouling: Coating can increase the hardness and anti-scratch performance of the lens surface, effectively protecting the photographic lens from scratches or contamination, and prolonging the service life. 4.Reduce halos and ghost images: Coating can effectively reduce the generation of halos and ghost images, making the image more realistic in color and clearer in detail. 5.Improve color reproduction performance: Coating can improve the dispersion properties of light, improve the lens's ability to restore color, and make the captured image more vivid and natural.  

As autonomous delivery becomes increasingly common in smart cities and commercial logistics, the delivery robot is quickly transforming from a novel idea into a reliable part of everyday life. Behind each robot’s ability to navigate streets, avoid obstacles, and deliver packages safely is a critical component: the camera lens. A high-quality delivery robot lens is essential for creating a stable and intelligent visual system. From wide-angle coverage to environmental durability, the performance of the lens defines how accurately a robot understands its surroundings. Wide-Angle Vision for Complex Environments Delivery robots operate in diverse and unpredictable environments—sidewalks, warehouses, shopping malls, or residential areas. A wide-angle robotics camera lens gives robots the field of view they need to detect pedestrians, pets, bicycles, and other obstacles in time. With a broader FOV, the robot’s perception module receives more complete visual information, making navigation smoother and reducing collision risks. For autonomous delivery systems that rely heavily on computer vision, this wide-angle coverage is indispensable. Low Distortion for Precise Object Recognition Accurate recognition depends on accurate imaging. If a lens introduces heavy distortion, the robot’s AI algorithms may misjudge distances or object shapes. A professional AGV lens or robotics lens minimizes distortion while maintaining clarity from the center to the edges. This ensures that visual data is clean and consistent, allowing machine-learning models to perform object detection, lane following, and path planning with higher precision. Reliable Performance in All Lighting Conditions Delivery robots often work day and night. This requires a lens that can handle everything from bright sunlight to dim indoor lighting. High-quality delivery robot lenses feature enhanced low-light performance, high transmittance, and optimized coating that suppresses glare and improves contrast. Whether the robot operates at noon or during late-night deliveries, the imaging remains stable and clear. Built for Outdoor Durability From rain and dust to temperature fluctuations, delivery robots face challenging environmental conditions. A robust robot camera lens is built with weather-resistant materials, anti-fog design, and mechanical stability to ensure reliable operation throughout the day. Applications such as sidewalk delivery, campus delivery, and commercial logistics all require dependable optical components that can endure long-term outdoor exposure. Powering Smart Logistics and Autonomous Mobility A well-engineered delivery robot lens plays a crucial role in multiple tasks: Autonomous navigation Obstacle detection Package recognition Indoor–outdoor transition Real-time monitoring As smart logistics continues to develop, the demand for advanced optics in delivery robots will only grow. High-precision lenses enable robots to move safely, respond accurately, and integrate seamlessly into modern intelligent delivery networks. Advancing the Future of Robotic Vision Optical performance is no longer just an accessory—it is a core part of a robot's intelligence. By combining wide-angle imaging, durability, low distortion, and stable performance, the next generation of delivery robot lenses will enable smoother, safer, and more efficient autonomous delivery operations.

In FPV (First-Person View) drone systems, the lens plays a central role in determining image clarity, latency, field of view, and overall visual feedback during flight. As FPV drones continue to be used in freestyle flying, racing, cinematography, mapping, and training, understanding how an FPV lens is designed and what technical parameters matter can help users choose more suitable optical solutions for their application scenarios. This article introduces the essential characteristics of an FPV drone lens, along with the optical design considerations that impact real-time flight perception. 1. Field of View (FOV): The Foundation of FPV Perception The Field of View determines how much of the environment is visible in the camera feed. For FPV flying, especially racing and freestyle, pilots typically prefer: Ultra-wide FOV (150°–180° equivalent) Allows better spatial awareness and smoother maneuvering Wide-angle distortion control Ensures the image remains recognizable and natural during fast movements A well-designed ultra-wide angle lens balances wide coverage with acceptable distortion levels, providing pilots with stable visual cues. 2. Optical Resolution and Image Sharpness Resolution affects how clearly the camera captures textures, positions, and details. Key factors include: Lens resolving power (MTF performance) Optical distortion level Chromatic aberration control Sensor compatibility (1/1.8", 1/2", 1/3", etc.) A high-resolution FPV drone lens should maintain consistent sharpness across the entire image, including the edges, as peripheral clarity is critical in wide-angle FPV feeds. 3. Latency Behavior and Optical Transmission Efficiency Latency in FPV systems is influenced by both the camera and the optical lens. Lens design affects latency indirectly through: Light transmission efficiency (T-value) Coating quality Internal reflections and stray light control A lens with high light transmission enables the sensor to obtain sufficient information more quickly, which supports low-latency FPV video transmission. 4. Aperture Size and Low-Light Performance FPV flying often occurs in variable lighting conditions — indoor spaces, sunset environments, tunnels, or shaded outdoor areas. A large aperture (e.g., F1.6 – F2.0) enables: Improved low-light visibility Reduced noise from the sensor More stable exposure in fast transitions Combined with appropriate anti-reflective coatings, a lens can maintain clear imaging in both bright and dim environments. 5. Lens Materials and Structural Durability FPV drones experience vibration, rapid acceleration, and occasional impact. Thus, the physical structure of the lens is as important as its optical performance. Considerations include: Glass versus hybrid (glass + resin) elements Lens barrel material (aluminum, PC/ABS, composite materials) Resistance to temperature changes Weight requirements for drone balance A stable optical structure ensures consistent focus performance across repeated flights. 6. Sensor Compatibility and Image Format Different FPV systems use different sensor sizes and aspect ratios. Matching the lens to the sensor ensures: Correct back focal distance Optimal coverage without vignetting Accurate focus position Proper use of the sensor’s full dynamic range Sensor formats commonly used in FPV include: 1/3", 1/2", 1/1.8" CMOS. 7. Application-Specific Lens Selection Different FPV use cases require different optical priorities: Freestyle FPV Wide FOV High image stability Controlled distortion FPV Racing Extremely low latency Fast light adaptation Edge-to-edge clarity Cinematic FPV Higher resolution Low-distortion imaging Color rendering accuracy Industrial FPV High contrast Consistent optical performance Robust housing design

A technical overview of imaging requirements and optical challenges in underwater environments Pool cleaning robots rely on a combination of mobility, sensing, and visual perception to navigate and perform cleaning tasks. While many people associate these robots with brushes, motors, and filtration systems, the camera lens is one of the most important components enabling accurate underwater monitoring and decision-making. 1. Why Pool Robots Need an Underwater Vision System Modern pool cleaning robots typically include at least one camera module. The camera serves several functions: Observing pool walls, corners, and the bottom surface Assisting with navigation and route planning Detecting debris, stains, or areas requiring repeated cleaning Avoiding obstacles such as steps, drains, or pool accessories Supporting real-time feedback or remote monitoring A well-designed underwater lens ensures that the robot collects reliable image information even in environments with reflections, turbidity, or inconsistent lighting. 2. Optical Challenges Unique to Underwater Imaging Unlike air, water significantly changes the behavior of light: Refraction and Field of View Loss Water has a higher refractive index, which reduces the effective field of view (FOV). To compensate for this, underwater lenses often require extremely wide viewing angles. Light Absorption and Scattering Water absorbs light more quickly, and suspended particles scatter it. This affects clarity, contrast, and color accuracy. Reflection From Surfaces Walls and the water surface can create strong highlights or glare spots. Pressure and Exposure Components must withstand long-term immersion, water pressure, and chemical exposure (chlorine, saltwater, cleaning agents). These conditions make underwater optical design fundamentally different from normal surveillance or consumer cameras. 3. Key Parameters in Underwater Lens Design (1) Focal Length (EFL) A shorter focal length provides a wider field of view. Underwater applications often require ultra-short focal lengths (e.g., 0.98mm–2mm) to counter refractive narrowing. (2) Aperture (F-number) A lower F-number (such as F1.6–F2.0) helps increase brightness in dim conditions, especially at the pool bottom or shaded areas. (3) Field of View (FOV) Wide-angle imaging is essential. Typical underwater lenses for pool robots might reach: Horizontal: 150°–180° Vertical: 150°–180° Diagonal: up to 200° Such panoramic FOV allows the robot to understand its surroundings with minimal blind spots. (4) Optical Structure (e.g., 2G3P) Hybrid lens structures combine glass and plastic elements to balance: Distortion correction Weight Thermal stability Cost-efficiency Glass elements improve durability and reduce optical deformation underwater. (5) Coating and Transmittance High transmittance (e.g., Tavg ≥ 90%) is crucial for: Reducing light loss Improving visibility in murky water Maintaining color fidelity Coatings also help resist scratches and chemical exposure. (6) Sensor Compatibility Underwater lenses are typically paired with sensors like Sony IMX390, which offer: High dynamic range Good color reproduction Low-light sensitivity Stability for continuous operation (7) Waterproof and Environmental Protection Protection levels such as IP67 or IP68 are essential to: Prevent water ingress Avoid fogging Maintain clarity during long-term submersion Operating temperature ranges like -20°C to +70°C ensure performance across seasonal changes. 4. Application Scenarios in Pool Cleaning Robots An underwater lens contributes to multiple robotic functions: Mapping pool geometry for navigation Detecting fine particles or patches of dirt Monitoring robot positioning relative to walls or slopes Supporting AI algorithms that classify debris or surface conditions Enhancing safety, reducing collision risks With a wide field of view and stable underwater imaging, the robot can operate more efficiently and autonomously. 5. Future Trends in Underwater Optical Design As pool cleaning robots become more advanced, underwater lenses will continue to evolve in the direction of: Higher resolution for better object detection Improved low-light imaging More durable materials for chemical resistance Enhanced anti-fog and anti-reflection coatings Integration with AI-based vision systems These improvements help robots adapt to both residential and commercial pool environments.

As drones continue to expand their role in aerial photography, inspection, mapping, and security applications, image quality has become a critical performance indicator. Among the many optical components, the large aperture drone lens plays an increasingly important role in improving aerial imaging performance, especially in challenging lighting conditions. What Is a Large Aperture Drone Lens? In optical systems, aperture size is expressed by the F-number. A smaller F-number indicates a larger aperture. A large aperture drone lens typically refers to lenses with apertures such as F1.1, F1.2, or F1.4, which allow significantly more light to reach the image sensor compared to standard drone camera lenses. This increased light intake is particularly beneficial for drones operating in low-light or high-speed flight environments. Advantages of Large Aperture Lenses in Drone Applications 1. Better Low-Light Performance Drones are often deployed during dusk, nighttime, or in environments with uneven lighting. A large aperture drone lens improves light-gathering capability, enabling clearer images with reduced noise and better detail retention in low-light aerial imaging. 2. Faster Shutter Speeds for Dynamic Scenes During high-speed flight or in windy conditions, motion blur can easily degrade image quality. With a large aperture, drone cameras can maintain faster shutter speeds without underexposure, resulting in sharper and more stable aerial footage. 3. Improved Signal-to-Noise Ratio When paired with high-resolution image sensors, a large aperture drone camera lens helps improve the overall signal-to-noise ratio. This leads to smoother tonal transitions, improved contrast, and more accurate color reproduction. Optical Design Challenges of Large Aperture Drone Lenses While large apertures offer clear imaging advantages, they also introduce greater optical design complexity. High-performance drone camera lenses must balance image quality, size, and weight through precise engineering, including: Advanced multi-element optical designs to control distortion and aberrations High-transmittance optical coatings to reduce flare and ghosting Lightweight mechanical structures suitable for drone payload limits Optimized compatibility with high-pixel CMOS sensors As a result, large aperture drone lenses are most commonly used in professional and industrial drone systems. Expanding Application Scenarios Today, large aperture drone lenses are widely used in night patrol drones, emergency response drones, security surveillance platforms, and cinematic aerial drones. In these scenarios, reliable image quality under complex lighting conditions is essential for mission success.
