61-6876-63 Dielectric Cube Beamsplitter Reflection: Transmission: 1:2 A = B = C: 20mm CSM33-20-550

Features

  • A cube beam splitter with 1:2 or 1:3 reflectivity and transmittance.
  • Combined with a half mirror, it can be a three-branch or four-branch optical system that distributes light equally.
  • Accurate branching characteristics can be obtained in wide wavelength bands of white and visible LED light sources.
  • Since a dielectric multilayer film is used for coating, light loss is small and light can be efficiently separated.
  • Since it is a cube type, the optical axis of the emitted light will not be translated if the beam is incident vertically.
  • Also, even if a beam of the same size as the effective diameter is injected, the transmitted or reflected light will not be lost or reduced. *Enter light from the prism side marked with ○.
  • * The spectral wavelength characteristics may differ when light is inserted from the opposite prism.
  • * When linearly polarized light such as laser light is used, the reflectivity and transmittance vary depending on the polarization direction.
  • * When strictly adjusting the branching ratio, tilt the polarization azimuth to 45 degrees or use circularly polarized light.
  • * The phase difference of the incident light is not stored in transmitted light or reflected light.
  • * Use a wave plate to compensate for the phase difference.
  • * Wavelength dispersion occurs in transmitted and reflected light due to the refractive index of the material and the thickness of the glass.
  • * In addition, chromatic aberration and spherical aberration may occur when a converging or diverging beam is injected.
