Lens application case 10--Haima

May 30, 2025

Wintop Optics, a leading domestic automotive optical solutions provider, leveraged its expertise in optical design and precision manufacturing to develop the YT-7009 ultra-wide-angle lens—optimized for next-gen AVM systems. Haima Auto, a user-experience-focused Chinese automaker, selected the YT-7009 as the "eyes" for its new flagship models’ surround-view systems.

Wintop YT-7009 Lens: Technological Highlights & Innovations

The YT-7009 delivers systemic innovations addressing core AVM pain points:

Exceptional Low-Light Performance:
Utilizes high-transmittance nano-coating (>95% light transmission) to suppress stray light. Compatible with large-format, high-sensitivity sensors, delivering clear, low-noise images even at moonlight illumination (<0.1 Lux).
Automotive-Grade Robustness:
- All-Metal Inner Barrel: Enhances mechanical/thermal stability, preventing defocus across -40°C to +85°C.
- IP69K Protection: Withstands high-pressure car washes and harsh weather.
- Vibration Resistance: Passes rigorous mechanical shock/vibration tests for long-term reliability.
Compact & Integration-Friendly:
Space-optimized design facilitates seamless embedding in mirrors, grilles, or tailgates.
