STILAR® 2.8/8

This high-resolution C-mount lens Stilar® 2.8/8 offers camera manufacturers and users characteristics that were previously not available on the market. The Stilar® 2.8/8 was developed specifically for camera systems that use the new 1.2“ sensors with a 21.43 mm imaging dimensions. The super-wide angle lens was designed to obtain both high relative illuminance and low light falloff. As a result, the Docter Optics Stilar® 2.8/8 is a vignette-free lens with high transmissivity in the visible range. The combination of those features makes it the choice of preference for machine-vision cameras, measurement cameras and industrial surveillance systems.
