Union Optic's quartz wedge depolarizer consists of two 3° wedges of crystal quartz. Usual wedge depolarizer consists of one crystal quartz wedge and a compensation fused silica to avoid big beam deviation, but the deviation is also very big for some precise instruments. Union Optic does not use fused silica plate to compensate the beam deviation, we use a crystal quartz plate with its optical axis along the propagation direction. Because the depolarizer is constructed by same material, so the beam deviation can be much better. The usual depolarizer can only be used at narrow band wavelength to avoid the big beam deviation. With our special design, our depolarizer can be used in a wide range of wavelength and keep the beam deviation in an acceptable range.
★Ideal for >6mm diameter Monochromatic Light & Broadband Light ★Better At 45deg Optical Axis Alignment ★Epoxy Cemented or Optically Contacted Available
Plane
polarized beam is not welcomed in some circumstances such as reflecting
spectrometer. A depolarizer will change the plane polarization into a
mix of polarization states by scrambling up the polarization, the result
is to change plane polarized beam into pseudo-depolarized beam and
produce depolarization. Depolarizer is widely used in polarization
sensitive instrument.

When
a beam hits on the depolarizer, there is a variable phase shift across
the beam aperture on the wedge, so a polarized beam can be effectively
depolarized. Quartz wedge depolarizer can work well with monochromatic
and broadband light source.Usually we can get better result if we orient
the input polarization state 45deg to the optical axis of the
depolarizer. And also the effectiveness of the depolarizer increases
with the size of the beam cross-section.
