-
- Composed of two cemented calcite prisms with their optical axes aligned parallel to their hypotenuse faces
- Extremely large extinction ratios for 2/3 of the aperture
- Angular fields are larger than those of Glan-Taylor prisms
- Angular field symmetric about prism assembly axis
- Virtually no deviation of extraordinary ray
- Mounted, fits to Microbench
- Uncoated
- Damage thresholds: CW lasers: 1 W/cm2; Pulsed lasers: 5 W/cm2
- Useable angular polarized field symmetrical with prism axis 14° - 16°
- Length/aperture ratio = 2.5
- Surface flatness : λ/4 @ 633 nm over the clear aperture
- Surface quality : 40-20 scratch dig, i.e. 5/ 2 x 0,16 (DIN ISO 10110)
- Transmission range 350-2300 nm, transmission (uncoated):
- 35-40 % at 350 nm
- 65-70 % at 400 nm
- 80-88 % beyond 500 nm
