PBS for High Power Laser
Available in Sizes Ranging From 5 mm to 2" (50.8 mm)
Reflects S Polarization by 90°
Five Wavelength Ranges Available
High quality (precision) coating with high LIDT
Polarizing Beamsplitters (PBS) are designed to split light by polarization state rather than by wavelength or intensity. PBS are often used in semiconductor or photonics instrumentation to transmit p-polarized light while reflecting s-polarized light. Optical isolators use PBS to eliminate feedback-induced damage. PBS are typically designed for 0° or 45° angle of incidence with a 90° separation of the beams, depending on the configuration.
WISOPTIC offers a wide variety of PBS in a
range of configurations including plate, cube, or lateral displacement.
Plate Beamsplitters are available in many sizes for optimized
performance when used with ultraviolet, visible, or infrared
wavelengths. Cube Beamsplitters are ideal for applications requiring
durability or simplified mounting or system integration. Lateral
Displacement Beamsplitters are designed to split the incident beam into
two displaced parallel beams.
Features:
Various sizes: 5 mm, 10 mm, 1/2" (12.7 mm), 20 mm, 1" (25.4 mm), 2" (50.8 mm)
5 Wavelength Ranges Available:
420 - 680 nm
620 - 1000 nm
700 - 1300 nm (1" Only)
900 - 1300 nm
1200 - 1600 nm
Extinction Ratio: > 1000:1
WISOPTIC' Polarizing Beamsplitting Cubes are offered in six sizes and with five beamsplitting coating ranges. These cubes separate the s- and p-polarization components by reflecting the s component with the dielectric beamsplitter coating, while allowing the p component to pass. These cubes are designed to be used with the transmitted beam, which offers an extinction ratio of TP:TS > 1000:1.
