Machine Vision Filters & Industrial Imaging Diffusers

Enhancing Imaging Accuracy with Filters and Diffusers

Machine vision filters and industrial imaging diffusers are essential components for controlling light transmission, improving contrast, and reducing interference. Filters help isolate specific wavelengths, while diffusers distribute light uniformly to minimize hotspots and shadowing-critical for consistent inspection, recognition, and measurement.

FRAMOS offers both off-the-shelf and custom solutions, from IR-cut and bandpass filters to neutral density and polarizing filters, all tailored to your camera, sensor, and lighting setup.
