M7.5 4.8mm 12.3MP Low Distortion Lens Applications

Core Application Scenes

This 12.3MP 940nm band pass lens is designed for compact optical systems that require both high-resolution imaging and selective near-infrared wavelength transmission. Unlike a conventional visible-light camera lens, its integrated 940nm band pass filter allows the optical assembly to be configured around a specific wavelength, making it suitable for specialized active-illumination and sensing systems.

The combination of a 4.8mm focal length and up to 78° diagonal FOV on a 1/2.3″ sensor provides broad scene coverage while maintaining less than 1% TV distortion. This makes the lens suitable for systems that require both a relatively wide viewing area and controlled image geometry.

Its F1.8 aperture is particularly useful for systems operating with limited available optical light, while the 0.1m M.O.D. allows close-range imaging. The 5.32mm T.T.L. and M7.5 × 0.25 mount further support integration into compact embedded camera assemblies.

The integrated 940nm band pass filter makes this lens particularly relevant to optical systems using 940nm illumination. Depending on the complete camera architecture, it can be evaluated for active infrared imaging, optical sensing, biometric imaging, and other wavelength-selective machine vision applications.

For applications where field of view and working distance need to be evaluated before selecting a final optical configuration, engineers can use the FOV Calculator.
