Product Family Description

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

TECHSPEC® 45º 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. TECHSPEC 45º Reflective Dichroic Color Filters are traditionally coated and feature an N-BK7 substrate. These filters are available in circular and square sizes.
