Shenzhen Zhongke Nanguang Technology Co., Ltd (CSSOPT), a professional manufacturer of high-precision industrial and surveillance optical lenses, officially launches the OKS-3651-A4-650 8MP ultra-low distortion lens. This fixed focal length lens is engineered for high-precision security monitoring, machine vision and industrial inspection, with a groundbreaking TV distortion of only -0.005% to deliver true-to-life, edge-to-edge sharp imaging.
Key Advantages of the 8MP Ultra-Low Distortion Lens
1. Near-Zero Distortion for True-to-Life Imaging
The biggest highlight of OKS-3651-A4-650 is its ultra-low TV distortion of only -0.005%, which is far lower than the industry average. This eliminates image stretching, warping and shape distortion at the edges of the frame, ensuring that the captured image is completely consistent with the real scene. It is especially critical for scenarios that require accurate object size measurement, license plate recognition, and true restoration of monitored scenes.
2. IP69 High-Grade Waterproof & Dustproof Performance
Reaching IP69 protection level, the lens can withstand high-temperature high-pressure water jet washing, dust, oil and humidity. It works stably in outdoor parking lots, factory workshops, construction sites, and other harsh environments, with no fogging, water ingress or performance degradation even in long-term outdoor exposure.
3. F2.0 Large Aperture & IR Night Vision Function
Adopting 4G2P+IR professional optical structure with multi-layer infrared anti-reflection coating, the lens ensures sufficient light intake under low-light conditions, and supports day-night switchable infrared imaging. It delivers clear, high-contrast images even in dimly lit environments, guaranteeing 24-hour non-stop reliable monitoring.
4. Excellent CRA Matching & Stable Imaging Quality
The chief ray angle is strictly controlled within 16.7 degrees, which perfectly fits the photosensitive chip of mainstream 1/3" sensors, effectively avoiding dark corners, vignetting and color cast on the edge of the picture. The lens maintains consistent and stable imaging performance under extreme low and high temperature from -40℃ to 85℃, with no focal shift or image quality decline.
5. Compact M12 Mount & Wide Compatibility
With a compact overall length of only 22.5mm and a standard M12*0.5 thread interface, the lens is widely compatible with mainstream 8MP IP cameras, security surveillance cameras, machine vision cameras, embedded vision modules and smart IoT devices on the market. The 0.6m to infinity focus range meets the needs of both close-range industrial inspection and long-range surveillance scenarios.
Main Application Scenarios
- High-precision license plate recognition & traffic monitoring
- Industrial machine vision & precision part inspection
- Commercial retail anti-theft & real scene restoration monitoring
- Outdoor perimeter security & all-weather surveillance
- Logistics barcode scanning & dimensional measurement
- Smart building access control & elevator monitoring
- Laboratory high-precision image acquisition
