Kowa LM1.7QS40 Fixed Lens | 1/2.5" 1.7mm S-Mount, f/4, 160 lp/mm Center Resolution, -0.32% Distortion, Machine Vision Optimized

The Kowa LM1.7QS40 is a wide-angle, high-resolution fixed focal lens designed for use with compact 1/2.5" image sensors, commonly found in industrial and machine vision systems. With a 1.7mm focal length and fast f/4 aperture, it provides an ultra-wide field of view, ideal for applications requiring close-range full-scene capture. The lens achieves exceptional image clarity with a center resolution of 160 lp/mm and edge resolution of 100 lp/mm, supporting modern high-resolution CMOS sensors up to 5MP+. The short back focus distance of 4.0mm in air makes it an optimal solution for space-limited embedded imaging systems.

Engineered with an S-mount for lightweight integration, the LM1.7QS40 minimizes optical distortion to just -0.32%, ensuring reliable and geometrically accurate imaging. Its focus range spans from 0.1 meters to infinity, and it remains stable across industrial temperature ranges from -10°C to +50°C. Optional customizations include internal element gluing for vibration resistance, IR-cut filters, and f-stop modifications. This lens is ideal for high-speed capture, precision robotics, barcode reading, embedded vision, and other machine vision tasks where space, clarity, and durability are critical.
