Target Applications & Compatible Devices
Core Application Scenarios
The 4.9mm M12 low distortion lens is highly optimized for integration into narrow, sealed housing enclosures where structural space is extremely restricted. Its lightweight 4P configuration and ultra-short 1.3mm back focal length make it an exceptional candidate for disposable medical endoscope lenses, non-invasive dental cameras, and veterinary otoscopes. Additionally, its clean 55° diagonal field of view prevents any fisheye bending, allowing this industrial lens to perform perfectly in hand-held barcode scanners, multi-angle retail payment terminals, pipeline inspection crawlers, and compact drones where every millimeter of physical clearance and gram of weight matters.
Compatible Device List
- Sensor Compatibility: Native design matching standard 1/4″ Megapixel CMOS and CCD sensor formats.
- Medical Equipment: Fits miniature endoscope camera housings, dental wands, and medical inspection scopes.
- Scanning Terminals: Complements micro-board engines for industrial PDA scanners and QR code turnstiles.
- Micro Board Cameras: Integrates with low-profile, customized SPI/I2C camera boards and IoT development modules.
- Custom Adjustments: Available with customized IR cut filters or distinct anti-fog coatings upon enterprise volume request.

Frequently Asked Questions
Q: Why is the ultra-short T.T.L. of 10.30mm important for my project?
A: A Total Track Length of 10.30mm makes this lens incredibly short and flat. It allows product designers to build extremely slim devices, such as hand-held probes, without changing the sensor mount bracket.
Q: Can this 4.9mm lens fit onto a larger 1/3″ or 1/2.5″ sensor?
A: No. This lens is strictly built for a 1/4″ image format. If paired with a larger sensor, it will block light from hitting the edges, causing heavy vignetting and black borders.
Q: How does the F2.4 aperture benefit medical or industrial probes?
A: Internal spaces like pipes or medical tracts have minimal ambient light. The larger F2.4 aperture pulls in more light, ensuring your video remains bright even when using low-power LEDs.
Q: Does a 4P lens component design handle shifting temperatures well?
A: The 4-Plastic (4P) matrix provides a lightweight, cost-effective, and highly shock-resistant layout. For extreme high-heat environments, please consult our staff to check our glass-hybrid alternatives.
Q: Does this low distortion lens require software calibration?
A: With optical distortion controlled below -1.2%, straight lines will remain visually straight. For most vision algorithms, you will not need to allocate processor power toward geometric software unwrapping.
Q: Is the iris adjustable for bright outdoor use?
A: No, this is a fixed iris lens. To adjust exposure levels under sunlight, you will need to utilize the electronic shutter settings built into your camera sensor.
