Kowa LM1.7QS25 | 1/2.5" 1.7mm Fixed Lens, 2MP, S-Mount, 3.2µm Pixel, 160 lp/mm Center Resolution, Visible Spectrum (400–800nm)

The Kowa LM1.7QS25 is a high-resolution, ultra-wide-angle 1.7mm fixed focal length lens designed for 1/2.5" sensors supporting up to 2MP resolution and pixel sizes as small as 3.2µm. With 160 lp/mm center resolution and 100 lp/mm at the image margins, it ensures edge-to-edge sharpness, even in compact embedded vision systems. This S-Mount lens is built with a compact body measuring Ø26.5 x 32.83mm and weighs just 18g, making it highly suitable for space-constrained applications such as drones, robotics, and automotive systems.

Optimized for the visible light spectrum (400–800nm), the LM1.7QS25 includes a fixed F2.5 aperture, manual focus, and a short 4.00mm back focus. The lens supports a 0.1m to ∞ focus range, enabling crisp imaging from close proximity to long distances. With a TV distortion of only -0.32%, it delivers geometric accuracy ideal for high-precision machine vision. The operating temperature range of -10°C to +50°C ensures durability in variable environments. Customization options are available including IR-cut filters, glued optics for vibration resistance, and modified aperture control.
