Beam Splitters

Beamsplitters are used to split or combine beam or light. Glass perfection can provide two types of beamsplitters: plates and cubes.

Beamsplitter Plates

This plate can be used with a high power laser. a thin film coating on the front surface of a beamsplitter changes the reflectance from that surface. we can fabricate it from BKY, MgF2etc. Also this beamsplitter includes narrow and broad band plates.

Beam Splitter Plate

Specifications:

Material: Optical Quality BK7 Grade
Dimension Tolerance: +- 0.2mm
Thickness Tolerance: +- 0.2mm
Surface Quality: 60-40 scratch and dig
Flatness: ^/4 @ 632.8 nm per 25 mm
Parallelism: 1 arc minute
T/R: 50/50
Beam Diviation: 60-40 scratch and dig
Wavefront Distortion: 3 arc minutes
Extinction ratio for transmitted beams: <^/4 @ 632.8nm
Principal Transmittance: >100:1
Principal Reflectance: Tp>98% and Ts<0.5%
Coating: Rs>99.5% and Rp<2%
Polarisation Beamsplitter Coating: On hypotenuse AR coating per face for faces

Beamsplitter Cube

Our beamsplitter cubes are made from two BKY glass right angle prisms cemented together at the hypotenuse. They do not exhibit ghotst reflections nor do they displace the transmitted beam, as plate beamsplitters do. They are optimised for a specific wavelength, or narrow wavelength range.

Beamsplitter Cube
