2.5mm wide lens

Product Brief Description

This premium 2.5mm IR board lens is independently developed and manufactured by BOSHI Optical Technology. It is an M12 wide angle lens tailored for 1/2.7” image sensors. This ultra‑wide surveillance component delivers an impressive 168.8° diagonal field of view, which effectively removes monitoring blind spots for multiple visual devices. Adopting F2.4 large aperture structure, this miniature camera lens delivers strong light‑gathering capacity to capture crisp footage both day and night. Benefiting from IR corrected optical design, this fixed‑focal security lens can sustain steady image clarity under visible‑light scenarios as well as infrared night‑vision conditions. Its compact TTL dimension hits 23.0±0.2mm, and such feature enables easy integration inside slim and compact camera modules. BOSHI Optical Technology executes comprehensive optical performance tests during mass production so every finished M12 wide angle lens can maintain dependable output. As a cost‑effective wide angle monitoring lens, this product gains extensive deployment within smart security cameras, robotic embedded vision equipment, vehicle auxiliary cameras and various intelligent visual terminals.

Detailed Product Description

Core Parameter

1. This 2.5mm IR board lens features 2.5mm effective focal length within plus‑minus five percent tolerance and F2.4 aperture within plus‑minus five percent tolerance. It acts as a standard M12 wide angle lens and maintains good compatibility with 1/2.7” image sensors.

2. Its total track length reaches 23.0±0.2mm while mechanical back focal length measures 2.82±0.2mm. The maximum image circle sits at Φ7.0mm and this dimension fully matches the corresponding sensor format requirements.

3. For field of view indicators, diagonal value reaches 168.8°, horizontal value reaches 142.6°, vertical value reaches 75.3°, and these figures establish this unit as a high‑performance ultra‑wide surveillance solution that supports panoramic coverage.

4. For optical indicators, TV distortion registers at -28.8%, relative illumination hits 45.0%, and CRA stays below 20.88°. Optimized CRA design helps prevent vignetting and color deviation, and the lens can work compatibly with mainstream CMOS sensors.

5. BOSHI Optical Technology calibrates each set of above‑mentioned optical indicators in the production phase to guarantee parameter conformity for every batch of the 2.5mm lens.

Performance Advantages

1. Ultra‑wide panoramic coverage capability. As a professional panoramic board camera lens, this product supplies extremely large field of view. Such feature helps users cut down the total quantity of deployed cameras and brings down comprehensive project expenditure. The wide angle lens can cover larger monitoring zones with fewer hardware units.

2. Mature IR corrected performance. This IR corrected M12 lens can realize unified focusing effect under daytime ambient light and infrared night‑vision surroundings. It successfully solves the infrared defocus defect that frequently troubles ordinary fixed focal security lens products on the market.

3. Outstanding F2.4 large aperture performance. This F2.4 miniature camera lens lifts overall low‑light imaging capability. It can output brighter and cleaner image content when working under dim surveillance environments, and delivers usable imaging result even with insufficient ambient illumination.

4. Well‑balanced edge picture quality. This wide angle monitoring lens achieves 45.0% relative illumination. It greatly alleviates dark‑corner phenomenon at picture edges while keeping distortion under reasonable control. Users can acquire usable image information from both central area and marginal area of the frame.

5. Universal M12 interface specification. This standard M12 thread mount structure supports fast assembly work and good interchangeability for most existing board camera modules. Engineers can conduct module assembling and lens replacement operations conveniently.

6. Stable performance among mass‑produced goods. BOSHI Optical Technology carries out strict optical inspection processes across the whole manufacturing workflow. Such measures ensure consistent optical performance for each finished 2.5mm IR board lens delivered to customers.

Application Field

1. Household and commercial security surveillance scenarios. This M12 wide angle lens fits indoor CCTV cameras, smart doorbells and panoramic monitoring hardware that demand broad viewing scope. The wide angle monitoring lens removes blind zones for home security and commercial site monitoring tasks.

2. Embedded machine vision scenarios. This ultra‑wide surveillance lens matches service robots, visual access control equipment and small‑size intelligent terminals equipped with 1/2.7” lens compatible image sensors. It serves as core optical component for multiple embedded vision lens related intelligent devices.

3. Vehicle auxiliary vision scenarios. The product adapts to vehicle surround‑view cameras and parking monitoring systems. These automotive devices require the broad viewing capacity brought by a panoramic board camera lens to observe surrounding vehicle conditions.

4. Consumer‑grade smart hardware scenarios. Compact mechanical structure of this fixed focal security lens makes it suitable for portable panoramic cameras and miniature image capture gadgets within consumer‑end market.

5. Miniature industrial monitoring scenarios. This compact F2.4 miniature camera lens can get installed inside industrial monitoring modules that occupy narrow installation space. It completes image acquisition work for compact industrial monitoring equipment.
