Wollaston Prism 38×28mm Wavelength Range 190 - 3500nm

WPPB-20-28SN

It is a prism for separating the incident beam into two linearly polarized beams with orthogonal polarizing direction. Used in the optical system of a phase-contrast microscope.
◦Outgoing beam is emitted with deviation. In this case, the emitted beams are in opposite directions depending on the orientation of polarization.
◦A single-layer anti-reflection coating has been applied on the surface of the Wollaston prism to proved higher transmittance.

  • If you need uncoated Glan Laser prism or anti-reflection coating with specific reflectance, please contact our Sales Division with your request.
Remark -
Attention
  • A change in the incident angle may also change the extinction ratio of the linearly polarized transmitted light.
  • Separation angle will vary depending on the wavelength. Please confirm the wavelength characteristic graph for separation angle.
  • Because of natural calcite crystals, there are individual differences, and variations in quality.
