Applications & Compatible Devices
Core Application Scenarios
This low distortion lens is specifically optimized for high-end machine vision and smart automated environments. It excels in automated optical inspection (AOI) lines, industrial robot alignment, and PCB defect scanning where geometric accuracy is vital. Its compact profile also makes it highly effective for automotive dashboards, driver monitoring systems (DMS), medical handheld endoscopes, and micro security surveillance setups where standard M12 lenses or C-mount lenses are too large to deploy.
Compatible Device List
- Fully compatible with 1/2.5″, 1/2.8″, and 1/3″ mainstream CMOS sensors (Sony, OmniVision, Onsemi).
- Fits specialized industrial smart cameras, smart biometric scanners, and compact IoT security modules.
- Seamlessly integrates into medical inspection wands and drone/UAV Gimbal cameras without modifying lens brackets.
- Supports tailored OEM/ODM adjustments for specific focal lengths, coatings, or FOV demands to match your hardware layout.

Frequently Asked Questions
Q: What makes this M7.5 lens suitable for machine vision if it is so small?
A: Despite its miniature size, it boasts a 5MP resolution and <-1% optical distortion. This ensures that pixels remain dense and lines remain straight, which is essential for precise industrial measurements and machine vision algorithms.
Q: Can this lens handle outdoor environments or day/night shifting?
A: Yes. It comes built-in with a 1IR cut filter to eliminate color standard deviation in daylight. For night vision setups, we can customize the lens without the IR cut layer or replace it with a dual-band pass filter depending on your system requirements.
Q: Is the M7.5 mount compatible with standard M12 or CS-mount holders?
A: No, it uses a smaller M7.5×0.35 threaded mount. It requires an M7.5 lens holder/mount block. If your device utilizes standard M12 lenses, you will need a step-down adapter or a matching M7.5 bracket.
Q: What is the benefit of the <-1% optical distortion feature?
A: Standard micro lenses often suffer from fish-eye stretching or barrel distortion. A rating of <-1% means the image edges remain flat and true-to-life, removing the need for heavy digital distortion correction software post-capture.
Q: What is the Minimum Object Distance (M.O.D.) for this lens?
A: The M.O.D. is 0.2 meters (20cm). It can sharply focus on objects as close as 20cm away from the lens front, making it excellent for close-range industrial scanning and desktop scanning devices.
Q: Does this lens support adjustable iris or focus tuning?
A: This is a fixed focal lens with a fixed F2.8 iris. The focus is set during installation by threading the lens into its mount to the correct back focal length (B.F.L. 1.5mm), then locking it in place with a set screw or glue.
