LN10115 6mm F1.1 Industrial Camera Lens M12, IR-CUT Precision Optical Design

LN10115-HD+H97+IR0175 Industrial Lens – Technical Overview

Precision Optical Design with Integrated IR Filter Switching for Day/Night Imaging

The LN10115-HD+H97+IR0175 is a high-performance fixed-focus lens engineered for industrial and surveillance imaging systems. With a focal length of 6mm and fast F1.1 aperture, it provides excellent light transmission and image clarity across 1/2.7" to 1/2.9" sensors. The lens features a 1G6P optical design with optimized distortion control and relative illumination. The integrated IR-CUT filter (model IR0175) automatically switches between IR-cut and clear glass elements based on lighting conditions, ensuring accurate color reproduction and enhanced IR response. With an M12 mount and industrial-grade construction, this lens is suitable for machine vision, automotive, robotics, and security applications.
