Dichroic Half-wave Plate 48WP-2-x-1-x

The half-wave plate rotates the polarization direction of a linearly polarized input beam of one single wavelength and not the other

Representative product images. Individual product images are found on the individual product pages.


The dichroic retardation plate (also known as waveplates or retarder plates) are λ/2 plates for one wavelength and do not affect the polarization of the other wavelength. The correctly positioned plate rotates two orthogonally polarized input beams of different wave lengths into linear polarization states in parallel. The dichroic retardation plates have a rotary mount and are designed to be integrated into the multicube system e.g. in dichroic Fiber Port Clusters.

  • Quartz plate, multiple order
  • Retardation λ/2 for one wavelength
  • Retardation λ/1 for the other wavelength (polarization is not affected)
  • For various wavelengths UV-IR
  • Clear aperture 5 mm
  • In adjustable mount with self-locking tubular axis (0 - 360°)
  • Rotation around axis that is inclined 2°  with respect to the optical axis. This avoids interference and back-reflection
  • System mount Ø 19.5 mm
  • Adjustable using Schäfter+Kirchhoff Polarization Analyzer series SK010PA.
