Sigma optical quartz depolarizer

Product Introduction

DEQ-1N is a single crystal substrate with a 2 ° wedge angle. Has a wide transmission wavelength spectrum. Due to the wedge angle, the transmitted light undergoes an angular deviation of about 1 °.
DEQ-2S is a depolarizer formed by direct contact between wedge-shaped crystals and synthetic quartz. Due to the wedge angle of synthetic quartz offsetting the beam deflection angle of the crystal, the beam will not deflect.
Due to the anti reflection film coating on both sides, it has high transmittance.
DEQ-20P is a depolarizer composed of two crystal optical contacts. It has the characteristics of a wide transmission wavelength spectrum and no beam deflection.
The polarizer is installed on a 30mm aluminum alloy frame.

▶ If there are special technical requirements for material, plate thickness, and wedge angle, please inquire at the sales department.

▶ To improve the depolarization effect, it is necessary to use a large aperture beam as much as possible. When the beam aperture is too small, complete depolarization may not be achieved.
▶ The polarization direction of the beam is required to be at a 45 degree angle to the optical axis.
▶ When observing the transmitted beam from a distance, it may separate into two beams.
▶ The depolarizer cannot be made into a completely unpolarized state. Please make sure to confirm if the usage method is correct before purchasing.
