2.6mm wide angle lens

1. Product Brief Description

This M12 board lens PL-WA2.6-14 is a high-performance ultra wide angle lens engineered by ShangHai SLIK Optical Technology CO., LTD for compact surveillance and embedded imaging systems. Built as a cost-effective panoramic lens solution, this F2.0 fixed lens delivers a massive 170° diagonal field of view to eliminate blind zones for home security and vehicle monitoring. Optimized exclusively for 1/2.9” image sensors, the CCTV optical lens maintains balanced edge brightness with 68.0% relative illumination and controlled chief ray angle under 21.5°, perfectly matching mainstream CMOS sensors. The compact TTL 20.0mm design enables easy integration inside miniature camera housings. ShangHai SLIK Optical Technology CO., LTD strictly controls manufacturing tolerances to guarantee consistent optical quality of this ultra wide angle lens for mass production. It serves as an ideal fisheye board lens for consumer cameras, smart doorbells, in-car vision and mini panoramic monitoring equipment.

2. Detailed Product Description

2.1 Core Parameter

Focal length 2.6mm with ±5% tolerance, paired with F2.0 large aperture, the M12 board lens ensures excellent light intake for low-light surveillance environments.

170°diagonal, 130°horizontal and 65°vertical field of view; Φ6.7mm maximum image circle fully covers 1/2.9” sensor without vignetting.

TTL 20.0±0.2mm and mechanical back focal length 4.45±0.2mm, supporting simple assembly into compact camera modules.

TV distortion of -20.0% is typical for ultra wide angle lens, facilitating panoramic coverage while remaining compatible with common distortion correction algorithms.

68.0% relative illumination and CRA＜21.5° effectively reduce dark corners and color shading on CMOS sensors, a key advantage of this CCTV optical lens.

Standard M12 thread mount ensures interchangeability with mainstream camera modules.

2.2 Performance Advantages

1. Extra-wide panoramic coverage: As a high-performance fisheye board lens, the 170° diagonal FOV minimizes dead areas, cutting the quantity of cameras needed for space monitoring.

2. Strong low-light adaptability: F2.0 wide aperture improves light collection, delivering cleaner footage in dim environments for home security lens applications.

3. Sensor-friendly optical design: Strictly controlled chief ray angle and high relative illumination stabilize peripheral image brightness and color uniformity.

4. Compact mechanical outline: Short total length supports ultra-thin camera designs widely required by vehicle camera lens and smart home devices.

5. Reliable mass production consistency: ShangHai SLIK Optical Technology CO., LTD conducts strict optical testing on every batch, ensuring stable performance for long-term OEM orders.

2.3 Application Field

1. Home security monitoring: This ultra wide angle lens is widely adopted for smart doorbells, indoor mini cameras and Wi-Fi surveillance cameras, providing full-area viewing of entryways and rooms.

2. Vehicle on-board vision: The M12 board lens works for dashcams, rearview cameras and panoramic parking assist systems to capture surrounding road conditions.

3. Small commercial surveillance: Ideal for retail shops, office corridors and elevator mini cameras; the panoramic lens reduces installation costs for full-space monitoring.

4. Embedded industrial vision: Suitable for compact equipment inspection, mini panoramic capture and small machine vision modules based on 1/2.9” sensors.

5. Consumer IoT cameras: Matches miniature IoT camera modules where size limitation and wide viewing range are core requirements of a high-quality CCTV optical lens.
