Subtractive Filters (Cyan, Magenta, Yellow)

  • High Saturation Dichroic Type
  • Matrix of Sizes and Sets
  • Precision Glass Substrate

Ideal for machine vision, dichroic filters are commonly used for color separation and contrast enhancement applications. Provided in unmounted versions, these filters are easily integrated into a variety of existing camera and illumination setups. In addition, dichroic filters provide wider fields of view not obtainable using narrow bandpass interference filters. A complete set of these dichroic filters is available in a Pre-Loaded filter wheel.

Typical configurations include photo enlargers, beam separation, and placing filters in front an imaging lens to selectively isolate spectral regions/colors. If the light source is already colored (ie, red LEDs), then a filter in front of the lens can be used to filter out unwanted ambient light.
