Product Family Description

  • Reflects Stated Color While Transmitting Remaining Visible Spectrum
  • Ideal for Color Separation Applications
  • Precision BK7 Substrates

Our Reflective Dichroic Color Filters are designed to be used at a 45° angle of incidence and will reflect the stated color while transmitting the remaining visible wavelengths. EO’s Reflective Dichroics boast higher performance and a better quality substrate than other readily available color processing filters. Each filter provides greater than 98% reflection over the specified color range and greater than 90% transmission of the remaining wavelengths.
