Product Model: 61-6884-33
Product Brand: SIGMAKOKI CO., LTD.

Features

  • When the polarization characteristics of the laser beam affect the measurement result in the diffraction grating of a spectrometer, the polarization state of the laser beam incident on the diffraction grating is disturbed by the depolarization plate.
  • DEQ-1N is a single plate quartz substrate with 2° wedges.
  • Wide transmission wavelength range is obtained.
  • Beca*** of the wedge, the transmitted light ca***s an angular displacement of about 1°.
  • DEQ-2S is a depolarizing plate made by bonding a quartz with a wedge and synthetic quartz.
  • Synthetic quartz wedges cancel out the crystal beam declination, so the beam does not b***.
  • Anti-reflection films on both sides provide high transmittance.
  • The DEQ-2OP is a depolarizing plate with 2 crystal pieces in optical contact.
  • It has a wide transmission wavelength range and the beam does not b***.
  • The depolarizing plate is mounted on a φ30 mm aluminum frame.
  • * In order to improve the effect of depolarization, it is necessary to *** as large a beam diameter as possible.
  • * If the beam diameter is small, sufficient depolarization cannot be achieved.
  • * The polarization direction of the incident beam must be 45 degrees from the optical axis.
  • * If the transmitted beam is observed over a long distance, it may be separated into two beams.
  • * The depolarizing plate cannot produce a completely unpolarized state.
  • * Please make sure that there is no mistake in the usage before purchasing.
