Description
The 2.5mm M7 Miniature Wide Angle Lens is a high-performance optical solution engineered for compact imaging applications demanding high resolution and minimal space. Featuring a 1/4″ image format and a crisp 2 MP resolution, this fixed focal lens delivers excellent clarity across a wide 85° diagonal field of view. Its hybrid 2G2P+IR cut construction ensures optimized light transmission while filtering out infrared interference for true-to-life color reproduction. With an ultra-low TV distortion of less than 1% and a short Total Track Length (TTL) of 15.04mm, this M7 miniature lens is the definitive choice for next-generation smart doorbells, wearable tech, and compact industrial vision systems.
Key Product Highlights
85° Wide-Angle Views with Sub-1% Distortion
Eliminate fish-eye warping. Most miniature wide-angle lenses suffer from severe edge stretching, but our optical design keeps TV distortion under 1%. You get clear, geometrically accurate images across the entire 85° diagonal field of view.
Crisp 2 MP Resolution in an Ultra-Compact Frame
High-definition micro-optics. This lens packs a true 2 Megapixel resolution into a tiny Φ12×11.05mm footprint. It solves the industry pain point where small-volume devices are forced to compromise on image sharpness.
Seamless M7 Thread Integration for Tight Spaces
Zero bracket modification required. The standardized M7x0.35 miniature mount allows direct installation into ultra-thin housings. With a short 15.04mm TTL, it drastically reduces the physical footprint of your device.
Hybrid 2G2P Optics with Integrated IR Cut Filter
Daytime color accuracy. The two-glass, two-plastic optical formula balances cost-efficiency with high thermal stability. The built-in IR cut filter blocks stray infrared light, preventing color shifts in bright environments.

Product Application Scenarios and Compatible Devices
Core Application Scenarios
This miniature low distortion lens is optimized for smart home access control, compact commercial security, and automated micro-inspection setups. It is uniquely suited for residential smart video doorbells, facial recognition access terminals, and slim-profile peephole cameras where wide coverage is needed from a recessed, flat mounting position. Additionally, its lightweight structure makes it ideal for medical pipestems, consumer drone positioning modules, and automotive interior cabin monitoring systems where device weight and space are strictly constrained.
Compatible Devices List
Engineered for seamless integration, this M7 lens perfectly pairs with 1/4″ mainstream CMOS sensors and can be adapted to standard 1/3″ or 1/2.8″ sensors operating in cropped window modes. It offers plug-and-play compatibility with Tuya IoT camera modules, Xiaomi-ecosystem smart doorbells, and low-power EZNIK hardware modules. The M7x0.35 threading effortlessly interfaces with customized PCB camera boards, USB inspection endoscopes, and industrial micro-vision sensors.
Designed for Smart Video Doorbell and Miniature Security Camera applications.
Frequently Asked Questions
Q: Can this lens be used with a 1/3-inch sensor?
A: This lens is optimized for a 1/4″ format. Using it on a larger 1/3″ sensor will result in dark corners or vignetting. We recommend sensor windowing or opting for our 1/3″ compatible equivalents.
Q: What is the benefit of the 2G2P structure compared to all-plastic (4P) lenses?
A: The two glass elements provide superior thermal stability and higher scratch resistance, ensuring the camera stays in focus even when exposed to direct sunlight or fluctuating outdoor temperatures.
Q: Does this lens support night vision imaging?
A: This specific lens comes with a fixed, integrated IR cut filter to optimize daytime color accuracy. If your application requires day/night switching via IR LEDs, please request our version without the integrated IR filter.
