Description
Streamline your micro-imaging systems with our ultra-compact 1.6mm M7 wide angle lens, meticulously engineered for space-constrained 1/5″ image sensors. Delivering a wide 116° diagonal field of view, this mini fixed focal lens captures expansive visual fields within hyper-confined environments without severe edge warping. Constructed with an optimized 2G2P+IR hybrid lens layout and an ultra-thin 10.31mm T.T.L., it offers equipment manufacturers a high-reliability, low-profile optical solution for precision medical diagnostics and micro-space industrial monitoring.
Key Product Highlights
- 116° Wide-Angle Perspective: Expands the viewing area to 100°(H) and 85°(V) to capture full structural layouts in a single frame.
- Sub-Centimeter Threaded Interface: Employs an ultra-miniature M7x0.35 mount profile, saving significant integration space.
- Thermal-Stable 2G2P+IR Matrix: Combines dual-glass elements with premium plastics and a built-in IR filter for vibrant color accuracy.
- Ultra-Thin 10.31mm T.T.L.: Features an exceptionally flat profile to fit inside slim diagnostic wands and low-profile housings.
- Fast F2.0 Fixed Aperture: Ensures bright visual output and minimizes exposure times under localized, low-light illumination.

Target Applications & Compatible Devices
Core Application Scenarios
The ultra-compact 1.6mm M7 wide angle lens is purposefully engineered for precision micro-imaging where physical device clearance is tightly restricted. Its sub-centimeter footprint and controlled distortion (< -3%) make it highly suitable for medical & endoscope lenses, including dental intraoral cameras, rigid laparoscopes, veterinary otoscopes, and disposable medical probes. Additionally, this miniature industrial lens functions perfectly in industrial micro-inspection setups, such as narrow engine block borescopes, multi-axis robotic hand grippers, high-density semiconductor test fixtures, and covert security peephole modules that require a broad view from a fixed, tight position.
Compatible Device List
- Sensor Compatibility: Native optical design matched for standard 1/5″ micro CMOS/CCD sensors and VGA active pixel matrices.
- Medical Instruments: Integrates easily into handheld medical inspection wands, dental scopes, and flexible endoscopic tubes.
- Industrial Borescopes: Direct mechanical fit for slim sewer pipeline crawler cameras and handheld industrial borescopes.
- Micro Smart Hardware: Fits ultra-lightweight spy-hole cameras, pocket-sized surveillance hardware, and miniature IoT equipment.
- Focus Adjustments: Features a fine manual focus thread structure allowing precise focal plane tuning during factory assembly.

Frequently Asked Questions
Q: Why use an M7 x 0.35 mount instead of a standard M12 lens holder?
A: The M7 miniature standard is built specifically for sub-centimeter camera designs. It reduces the mechanical diameter significantly compared to M12 lenses, which is vital for building slim medical and industrial endoscope probes.
Q: Can this 1.6mm lens fit onto a larger 1/3″ or 1/4″ sensor board?
A: No, this optical design is optimized for a 1/5″ image format. If mounted onto a larger sensor, the image circle will clip, causing severe vignetting or solid black borders on the edges of your video.
Q: What are the benefits of the 2G2P+IR hybrid construction?
A: The 2 outer glass (2G) layers offer excellent scratch resistance and easy cleaning in humid testing areas. The 2 plastic (2P) elements keep the optical weight low, while the integrated IR filter prevents daytime color shifting.
Q: How does the < -3% distortion level affect my vision software?
A: Unlike heavy fisheye lenses, this wide angle lens controls distortion below -3%. Straight lines remain relatively straight on screen, allowing your software or inspectors to track shapes without massive software flattening.
Q: Is this miniature lens waterproof for medical or subsea pipe operations?
A: The lens elements are tightly sealed within the barrel. However, to achieve full IP67/IP68 waterproof or medical sterilization standards, you must seal the thread connection with epoxy during your camera module’s final housing assembly.
Q: How do I adjust the focus on this fixed focal lens?
A: It supports manual focus. During your product assembly phase, you simply rotate the lens body deeper or shallower into your M7 lens holder thread until your target depth of field becomes perfectly sharp.
