Kowa LM1.7QS40 1/2.5" 1.7mm Fixed Lens S-Mount, f/4 Aperture, 160 lp/mm Center Resolution, Wide Angle for Machine Vision

*Please note this product is subject to tariff fee*

The Kowa LM1.7QS40 is a precision-engineered 1.7mm wide-angle lens tailored for 1/2.5" CMOS sensors in space-constrained machine vision setups. Featuring a fixed f/4 aperture and 4.0mm back focus, it enables seamless integration with compact board-level cameras. This S-mount lens delivers high-performance imaging with 160 lp/mm resolution at center and 100 lp/mm at the edges—ideal for extracting fine detail in embedded vision and industrial inspection tasks.

Designed with distortion control in mind, the lens limits TV distortion to just -0.32%, ensuring geometric accuracy across the frame. Its 0.1m to infinity focus range and temperature tolerance from -10°C to +50°C support continuous use in demanding environments. The LM1.7QS40 also supports custom options such as IR-cut filters, glued optics for shock resistance, and aperture modifications, making it an adaptable tool for OEM vision systems, robotics, factory automation, and embedded AI vision modules.
