Description
Expand your visual capabilities in confined environments with our ultra-miniature 0.9mm M7 fisheye lens, precision-engineered for compact 1/5″ image sensors. Featuring an impressive 150° diagonal field of view, this micro fixed focal lens captures immersive, ultra-wide-angle perspectives where spatial layout constraints are absolute. Built with a specialized 2G2P+IR hybrid optical structure and a micro M7x0.35 threaded mount, it provides equipment developers with a reliable, ultra-slim visual component for precise close-up inspections and real-time medical imaging.
Key Product Highlights
- 150° Ultra-Wide Fisheye View: Captures a panoramic 150°(D) / 120°(H) field of view to eliminate blind spots in ultra-confined spaces.
- Micro M7 Threaded Interface: Employs an ultra-miniature M7x0.35 mount profile, ensuring direct integration into sub-centimeter housings.
- Optimized 2G2P+IR Optical Matrix: Combines dual glass and plastic elements with an integrated IR filter to retain high contrast and true colors.
- Super-Short 11mm T.T.L.: Features an incredibly compact 11mm total track length, reducing overall sensor probe thickness.
- Fast F2.0 Fixed Aperture: Draws ample illumination into small sensors to guarantee bright video feeds inside low-light target areas.

Target Applications & Compatible Devices
Core Application Scenarios
The ultra-miniature 0.9mm M7 fisheye lens is explicitly tailored for high-accessibility medical and micro industrial environments where conventional M12 lenses cannot fit. Its sub-centimeter footprint and wide-angle view make it an indispensable choice for medical & endoscope lenses, including disposable dental cameras, non-invasive laparoscopes, ENT otoscopes, and electronic capsule endoscopes. Furthermore, this miniature lens thrives in specialized industrial lens layouts like micro-diameter pipeline crawler robots, interior engine block inspection scopes, high-density electronic testing jigs, and spy-hole security modules that demand maximum area coverage from a static positioning point.
Compatible Device List
- Sensor Compatibility: Universally matched for 1/5″ micro CMOS/CCD image sensors and sub-VGA active pixel arrays.
- Medical Instruments: Integrates seamlessly into ultra-slim medical camera wands, flexible endoscope tubes, and diagnostic probes.
- Industrial Scopes: Direct screw-in solution for handheld borescope engines and specialized sewer inspection cameras.
- Micro Drone Hardware: Fits lightweight UAV camera modules, micro FPV setups, and pocket-sized surveillance rigs.
- Custom Adjustments: Provides variable manual focus threading arrays and alternative anti-fog or anti-scratch front lens coatings upon commercial requests.

Frequently Asked Questions
Q: Why is an M7 mount used instead of a standard M12 mount?
A: The M7x0.35 mount is an ultra-miniature standard specifically made for micro cameras. It shrinks the housing diameter by nearly 40% compared to M12 lenses, which is vital for building slim medical or industrial endoscope probes.
Q: Does this 0.9mm lens work with a 1/3″ or 1/4″ camera sensor?
A: No. This lens is optically balanced for a 1/5″ image format. Using it on a larger sensor will restrict the light pool, leading to extreme vignetting and massive circular black borders on your screen.
Q: How does the 150° fisheye distortion affect my visual feed?
A: With a TV distortion profile of <-10%, the lens produces a characteristic curved wide-angle perspective. This curved view allows you to inspect an entire internal pipe or body cavity wall simultaneously without rotating the camera probe.
Q: What are the durability benefits of the 2G2P+IR construction?
A: The 2 front glass elements provide exceptional scratch resistance and easy cleaning inside humid environments, while the 2 plastic elements keep the layout lightweight. The integrated IR filter prevents color distortion from external light.
Q: Is this miniature lens waterproof for medical or subsea pipe use?
A: The lens body itself is tightly sealed. However, to achieve full IP67/IP68 waterproof or medical-grade sterilization compliance, the lens must be properly sealed with epoxy inside your camera module’s final housing.
Q: Can we adjust the focus distance of this lens manually?
A: Yes, it features manual focus adjustment. You can accurately dial in your target depth of field by gently rotating the lens body inside your M7 lens holder during the module calibration phase.
