Description
Optimize your micro-imaging devices with our high-performance 1.9mm M8 wide angle lens, expertly engineered for space-constrained 1/5″ image sensors. Featuring an ultra-bright F1.8 aperture and an integrated IR-cut filter, this fixed focal lens delivers exceptional low-light sensitivity and true-to-life color accuracy. With a controlled TV distortion profile of less than -3% and a short 11.21mm T.T.L., it serves as a highly reliable, compact optical component for developers who demand crystal-clear close-up imaging without the bulky footprint of standard lenses.
Key Product Highlights
- Ultra-Bright F1.8 Aperture: Draws in maximum light to ensure vivid, noise-free video feeds even under low-power LED illumination in sealed spaces.
- Micro M8 Threaded Profile: Employs an ultra-miniature M8x0.5 mount, allowing effortless, direct integration into sub-centimeter camera housings.
- Integrated IR-Cut Filter Protection: Blocks unwanted infrared glare during daytime operations to guarantee stable, professional-grade color fidelity.
- Balanced 72° Horizontal View: Provides an efficient 90° diagonal wide-angle field of view, expanding coverage without heavy fisheye geometric warping.
- Thermal-Stable 2G2P Structure: Utilizes a premium 2-glass, 2-plastic hybrid lens component setup to prevent focus drift caused by rising temperatures.

Target Applications & Compatible Devices
Core Application Scenarios
The 1.9mm M8 wide angle lens is specifically tailored for micro-space medical diagnostics and localized industrial inspections where structural housing space is minimal. Thanks to its rapid F1.8 aperture, this micro lens excels as a high-performance choice for medical & endoscope lenses, including dental intraoral inspection wands, rigid veterinary laparoscopes, and non-invasive medical scopes. Additionally, this miniature industrial lens functions perfectly in industrial applications such as narrow pipeline inspection crawlers, robotic finger-tip vision modules, automated ATM deposit scanning windows, and micro-UAV hovering sensors that require crisp object mapping from a fixed close-range position.
Compatible Device List

Frequently Asked Questions
Q: What are the main benefits of an M8 mount over standard M12 lenses?
A: The M8x0.5 thread is significantly smaller than a traditional M12 lens body. It shrinks the overall diameter of the camera probe, which is essential for non-invasive medical scopes and micro-sized industrial tools.
Q: Can this 1.9mm lens be used on a larger 1/3″ or 1/4″ camera sensor?
A: No. This lens has an optical image circle optimized exclusively for a 1/5″ image format. Installing it on a larger sensor will clip the outer frames, causing heavy circular black borders (vignetting).
Q: How does the F1.8 aperture help inside dark pipes or medical cavities?
A: Deep, enclosed areas have very poor ambient light. The large F1.8 aperture pulls in a massive amount of light, allowing your miniature LEDs to fully illuminate the area without pushing your camera sensor into noisy ISO settings.
Q: Why does this lens feature a 2G2P hybrid lens component structure?
A: The 2 front glass elements provide hard scratch resistance and stable thermal clarity against fogging or heat, while the 2 plastic elements ensure the lens remains lightweight and highly cost-effective for mass production.
Q: Is there a version of this lens available without the built-in IR-cut filter?
A: Yes, we offer customization options. If your application relies on full near-infrared (NIR) night vision or laser tracking, we can manufacture this model with an AR coating or a clear window instead of the IR-cut filter.
Q: How do I adjust the focal plane for my specific target distance?
A: This lens supports manual focus. During your product assembly phase, you simply thread the lens barrel deeper or shallower into your M8 holder until your target depth of field achieves perfect edge-to-edge sharpness.
