特徴

• It is a special polarizing element with low transmission loss and high extinction ratio of 5×10^-5 or less.
• Use for high-precision polarization experiments.
• Calcite type for use in the visible to infrared region and α-BBO crystal type for use in the ultraviolet region are available.
• The Grantomson prism is enclosed in a metal frame, and the element is not stressed when the frame is fixed to the holder.
• The calcite type Granthomson prism allows you to select the allowable angle of incidence in two levels.
• The surface of the Grantomson prism is coated with a single layer of antireflection film to provide high transmittance.
• Gran laser prism GLPB/GLPC and Wollaston prism WPPB/WPPC for high power laser are also available.
• Please check the allowable angle if necessary.
• * When the incident angle changes, the extinction ratio of the linearly polarized light of the transmitted light also changes.
• * All light that does not pass through the Grantomson prism is absorbed and scattered on the side of the device.
• * Since calcite is a natural crystal, there are variations in the quality and individual differences.
• * If a light beam is inserted into the polarizing prism at an incidence angle greater than the allowable angle, the light may not be extinguished.
• * The center axis of the allowable angle depends on the direction and wavelength of the prism, and may have an angle to the optical axis of the polarizing prism.
