1.5mm Fisheye Lens

Product Brief

Manufactured by BOSHI Optical Technology, this compact fisheye lens features 1.5mm focal length and F2.2 aperture, perfectly matched for 1/4 inch AR0144 sensor. It delivers 200 degree field of view to capture extensive scene coverage within limited installation space. The well optimized optical structure guarantees stable relative illumination and controlled chief ray angle for consistent sensor performance. This board camera lens adopts M12 mount for easy assembly into miniature camera modules. It serves diverse industrial and surveillance projects, bringing reliable imaging output for mass production and prototype testing. Every unit from BOSHI Optical Technology undergoes strict optical inspection to satisfy high volume customer requirements.

Product Detailed Description

1. Detailed Parameter

- This ultra wide angle lens comes with 1.5mm focal length within 5 percent tolerance, paired with F2.2 aperture at 5 percent tolerance to balance imaging brightness and depth of field. Its total track length reaches 13.03mm plus minor tolerance range, and back focal length measures 3.08mm for proper sensor fitting.

- Designed for 1/4 inch AR0144 sensor, the fisheye lens provides diagonal 200 degree field of view, 167 degree horizontal field of view and 118.4 degree vertical field of view. Distortion value hits negative 85.0 percent typical for large angle fisheye effect. Relative illumination achieves 65.0 percent while CRA stays below 18.0 degree to avoid vignetting risk for target sensor. Standard M12 mount supports direct installation for common board camera hardware.

2. Detailed Performance Advantage Analysis

- The 1.5mm focal length and F2.2 aperture cooperate to realize good light intake, supporting clear imaging under medium low‑light environments without extra auxiliary light source. The controlled CRA below 18.0 degree matches the receiving feature of 1/4 inch AR0144 sensor and reduces image corner darkening.

- 65.0 percent relative illumination keeps uniform brightness across frame, which improves overall picture quality of this board camera lens. 200 degree field of view removes blind spots so single camera unit can cover much larger monitoring zone. Compact total track length supports miniaturized module design for space‑limited equipment. Standard M12 mount enables fast replacement and compatibility with mainstream camera housing parts. Strict tolerance control from BOSHI Optical Technology ensures consistent optical performance among mass produced lens batches.

3. Detailed Application Field Analysis

- Surveillance equipment: This fisheye lens fits indoor mini security cameras for retail shops and small offices, leveraging 200 degree field of view to monitor whole room area via single device.

- Industrial vision modules: The 1/4 inch AR0144 sensor compatible lens works for equipment peripheral monitoring and machine auxiliary visual inspection with compact module demand.

- Smart home devices: Applied inside home monitoring cameras and visual doorbell units, where 1.5mm focal length offers wide scene capture within small product casing.

- Automotive auxiliary vision: Suitable for short‑range surrounding view camera modules to observe vehicle nearby environment.

- Consumer miniature camera projects: Used for custom USB camera development and prototype verification by research institutes and product developers.
