Filter for Imaging applications   

470 BPF   

This dielectric optical filter from Iridian Spectral Technologies has been designed for machine vision, imaging, and other applications.

Depending on the model chosen, the filter will pass specific UV, visible, or IR wavelengths and block out unwanted wavelengths.

The filters can be used to improve image contrast or isolate spectral regions and colours. They are very durable and offer:

  • Steep edges (cut-offs down to 40 cm-1)
  • High transmission (> 94%) and high blocking (> OD 3)
  • Optimised for use with various LED light sources
  • Selection of threaded mount sizes available from M25.5 to M62
  • Other standard colour wavelengths and bandwidths available, custom ones on request
