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.
