Description
Discover the perfect optical solution for compact imaging systems. This 2MP 2.0mm M7 mini wide angle lens features a 1/4″ image format, 130° diagonal field of view, and ultra-low TV distortion (< -1%), delivering crystal-clear, expansive visuals without edge bending. Engineered with a 3G1P+IRF optical structure, this fixed-iris miniature lens provides high-definition performance for smart doorbells, automotive rear-view cameras, medical endoscopes, and industrial vision setups where space is premium.
Product Highlights
- Ultra-Wide 130° Distortion-Free FOV: Captures an expansive 130° diagonal (110° horizontal) view with less than 1% TV distortion, eliminating the fish-eye bending common in wide lenses.
- Ultra-Compact M7 Miniature Mount: Features a micro M7x0.35 mount and a tiny 10.07mm T.T.L., perfectly fitting into highly space-constrained IoT and medical devices.
- Crisp 2 Megapixel HD Resolution: Optimized for 2MP CMOS sensors to deliver sharp, high-contrast images from the center to the very edges of the frame.
- 0.1m Close-Up Focus (M.O.D.): Boasts a 0.1-meter Minimum Object Distance, making it exceptional for macro industrial inspection and close-range diagnostic imaging.

Applications & Target Devices
This M7 miniature wide angle lens is engineered for high-density, small-footprint environments that refuse to compromise on image clarity. It serves as a core optical component for smart smart home ecosystems, automotive safety devices, and precision medical equipment. The 3G1P+IRF construction ensures optimal color rendering and light transmission even in fluctuating outdoor temperatures or low-light conditions, preventing focal shift. By integrating a built-in IR cut filter, it effectively blocks infrared interference, providing true-to-life color fidelity for daily surveillance and automated scanning tasks.
Compatible Device List:
- Smart Home IoT: Perfect for smart video doorbells, peephole cameras, and compact indoor security pods.
- Automotive Systems: Ideal for flush-mount backup cameras, cabin monitoring systems (OMS), and blind-spot detection modules.
- Medical & Industrial Inspection: Tailored for disposable medical endoscopes, dental cameras, oral scanners, and micro-robotic arms.
- Miniaturized Surveillance: Fits 1/4″ CMOS sensors from Omnivision, Sony, and Smartsens used in custom Tuya or Mi Home smart cameras.
Designed for compact smart security, automotive rear-view, and micro-medical imaging applications.
Frequently Asked Questions
Q: Can this M7 lens be used with 1/3″ or 1/2.8″ sensors?
A: This lens is optically optimized for 1/4″ image formats. Using it with larger sensors like 1/3″ or 1/2.8″ will result in severe dark corners or vignetting.
Q: What does the “3G1P+IRF” optical construction mean?
A: It means the lens elements consist of 3 Glass lenses and 1 Plastic lens, plus a built-in IR Filter (IRF). The glass elements ensure high thermal stability and clarity, while the IR filter blocks unwanted infrared light for precise color reproduction.
Q: Does this low distortion lens require software calibration?
A: No. With a TV distortion rating of less than 1%, the optical design naturally corrects straight lines, meaning you get a flat wide-angle view right out of the box without needing digital de-warping software.
Q: Is the focus adjustable, or is it a fixed focus lens?
A: It is a fixed-focal lens (2.0mm) with a Fixed Iris. Once threaded into your camera board module and locked at the optimal focal point, it stays fixed.
Q: What is the benefit of the 10.07mm T.T.L. length?
A: The ultra-short 10.07mm Total Track Length (T.T.L.) makes the physical profile of the lens extremely shallow. This allows camera manufacturers to build ultra-thin hardware housings for doors, vehicle bumpers, or medical probes.
Q: Can we request a custom mount or different IR filter coatings?
A: Yes, we offer OEM/ODM customization services. We can adjust the IR filter wavelength (e.g., 650nm, 850nm, or dual-band) and mechanical mount dimensions based on your project volume.
