Detailed Product Description

Parameter

This board lens matches 1/2.7” sensor with Φ6.9mm max image circle. It has 2.5mm EFL, F2.0 aperture with ±5% tolerance, D/H/V FOV of 153°/125°/66°. External dimension is Φ14.0×16.76mm, optical total length 22.0±0.3mm. TV distortion ≤-24%, relative illumination ≥55%, chief ray angle 13.2°. The fixed focus lens uses M12×P0.5 interface, operating within -20℃ to 75℃. ShangHai SILK Optical Technology CO., LTD precisely calibrates every optical parameter to maintain consistent batch performance for this compact lens.

Performance Advantages

The ultra wide lens offers ultra-large diagonal field of view to capture more scene area, reducing the required number of cameras for full coverage. F2.0 large aperture improves light intake, supporting imaging under low-light conditions. Relative illumination ≥55% suppresses dark corners, delivering uniform image brightness. The structure design ensures stable optical performance across wide temperature range, resisting thermal expansion impact. This imaging lens has compact outline for mini camera module integration. Controlled distortion balances wide-angle capture and recognizable image content. ShangHai SILK Optical Technology CO., LTD implements strict optical inspection for each cctv lens unit to guarantee long-term reliability.

Application Field

The wide view lens fits multiple imaging scenarios. For vehicle systems, this board lens works for surround view and interior monitoring cameras. In security industry, it serves cctv monitoring, smart home cameras and doorbell visual modules. This fixed focus lens also applies to industrial machine vision, IoT visual devices and small intelligent recognition equipment. The compact lens can be integrated into miniature camera modules where space is limited. ShangHai SILK Optical Technology CO., LTD provides customizable optical tuning service for this imaging lens to meet special demands from different vehicle lens and visual system projects.
