Kowa LM35JS5MA 35mm F0.85 Fixed Lens for 1" 5MP CS-Mount Cameras with Auto Iris DC and NIR Coating

*Please note this product is subject to tariff fee*

The Kowa LM35JS5MA is a high-performance 35mm fixed focal length lens built for 1" format CS-mount cameras up to 5 megapixels. With a super-fast F0.85 aperture and AI-DC auto iris control, this lens is engineered to excel in extreme low-light conditions across both visible and near-infrared spectrums (400–1000nm). Designed for high-precision imaging in ITS, traffic control, perimeter security, and industrial machine vision, it supports manual focus and delivers excellent resolution and contrast.

Optimized for pixel sizes around 3.5–4.5µm, the LM35JS5MA is ideal for applications where low frame rate, high sensitivity, and wide aperture are critical. Its broadband coated optics enhance transmission and suppress ghosting and flare. The lens features a CS-mount, M77 x 0.75 filter thread, and rugged build quality for reliable operation from -10°C to +50°C. Included is a 25cm 4-pin cable for iris control, and the housing measures 78.5mm x 145mm, weighing in at 1200g, making it suitable for robust fixed installations.
