Optical Filters

Often underestimated, industrial optical filters used in image processing systems can significantly improve quality, mechanically protect the lens and eliminate the influence of ambient light. Our range is perfectly adapted to the requirements of image processing and offers you a large selection of bandpass, longpass and short pass filters. Optical filters for UV or infrared illumination allow you to improve quality in ways never before achieved.

Standard bandpass filter


Ideal for monochrome LED lighting applications.

Narrow bandpass filter


Ideal for forensic and scientific applications.

Interference bandpass filter


Ultrasonic narrow band interference filter, ideal for laser applications.

Multi bandpass filter


Allow several narrow spectra to pass, one of them in the NIR range, for applications in the ITS range.

Longpass filter


Allow a wide spectrum of longer wavelength light to pass through.

Acrylic filters


Acrylic protective filters as an alternative for areas where glass is unsuitable, such as FDA applications.

Shortpass/ Near-IR Cut filters


Blocks longer visible (VIS) and near infrared (NIR) wavelengths.

Polarizing filters


To reduce reflections and increase contrast and color saturation.

Neutral density filters


To reduce light intensity without affecting colour and contrast.

Light balancing filters


To correct the colour temperature of white light sources such as Xenon.

Protective filters


To protect against dirt, dust, liquids etc. without impairing the image quality.

Filter Kits


Filter kits for a wide range of machine vision applications.
