The reason the wavelength region which can be used as light polarizer is large, it is the optimal light polarizer for a spectrophotometer or an ultraviolet lamp light source use.
"DUV Glan-Thompson Polarizer" is a completely different structure as compared with the common Glan-Thompson prism polarizer. Calcite is not used, Only using a transparent material to a ultraviolet light region, the part which is usually an adhesive layer is transposed to a crystal, and it is assembling by optical contact.
From the reason for the above, a DUV Glan-Thompson prism shows the characteristic which was excellent in the usual Glan-Thompson prism also by the short wavelength side.
However, it is not in the polarizer for high-power laser, because each components are assembled by optical contact.
