Improve and Simplify Machine Vision

There is a wide range of optical filters for industrial machine vision. Filters allow you to achieve amazing results, improve the visibility of specific details and often significantly simplify your machine vision task.

A bandpass filter coordinated to the light used, for example, allows you to almost completely filter out often overwhelming ambient light. Also, in normal applications, often invisible properties of objects are made visible using suitable filters.

Benefits of optical filters:

  • Suppress ambient light
  • Increase measuring accuracy
  • Increase contrast
  • Improve color rendering
  • Suppress overwhelming wavelength ranges


Polytec offers you a wide range of different filters for virtually every lens.
