Technology

How Dichroic Mirrors Work

Dichroic mirrors use thin-film interference coatings to selectively reflect certain wavelengths while transmitting others. Multiple layers of materials with different refractive indices create constructive interference for specific colors.

  • Precision multi-layer optical coatings
  • Sharp cut-off wavelength transitions
  • Minimal absorption losses
  • Angle-dependent spectral characteristics
