2. Detailed Product Description

 Core Parameter

- This 2.5mm IR board lens features 2.5mm effective focal length (±5%) and F2.4 aperture (±5%), a standard M12 wide angle lens compatible with 1/2.7” image sensors.

- Total track length reaches 23.0±0.2mm, mechanical back focal length is 2.82±0.2mm; maximum image circle Φ7.0mm perfectly matches sensor format requirements.

- Field of view: diagonal 168.8°, horizontal 142.6°, vertical 75.3°, making it a high-performance ultra wide surveillance lens for panoramic coverage.

- Optical specifications: TV distortion -28.8%, relative illumination 45.0%, CRA <20.88°. The optimized CRA design avoids vignetting and color deviation, fully adapting to mainstream CMOS sensors.

3. Performance Advantages Analysis

- Ultra-wide panoramic coverage: As a panoramic board camera lens, the extra-large field of view reduces required camera quantity and lowers overall project costs.

- IR correction capability: This IR corrected M12 lens realizes unified focusing under daylight and infrared night vision, eliminating infrared defocus issues common in ordinary fixed focal security lens.

- F2.4 large aperture: The F2.4 miniature camera lens improves low-light imaging performance, offering brighter, cleaner images under dim surveillance environments.

- Balanced edge image quality: The wide angle monitoring lens maintains 45.0% relative illumination, effectively mitigating dark corners at image edges while controlling distortion.

- Standard M12 interface: Universal M12 thread mount supports quick assembly and interchangeability for most board camera modules.

- Reliable batch consistency: ShangHai SLIK Optical Technology CO., LTD implements rigorous optical inspection throughout production, ensuring stable optical performance of each 2.5mm IR board lens.

4. Application Field Analysis

- Home & commercial security surveillance: This M12 wide angle lens is ideal for indoor CCTV cameras, smart doorbells and panoramic monitoring equipment requiring broad viewing coverage.

- Embedded machine vision: The ultra wide surveillance lens fits service robots, visual access control devices and small intelligent terminals with 1/2.7” sensors.

- Vehicle auxiliary vision: Perfect for vehicle surround-view cameras and parking monitoring systems that demand the wide field of view of a panoramic board camera lens.

- Consumer smart hardware: Suitable for portable panoramic cameras and miniature visual capture devices, thanks to the compact structure of this fixed focal security lens.

- Mini industrial monitoring: The compact F2.4 miniature camera lens can be installed in narrow-space industrial monitoring modules.
