Beam splitters take on many forms, cubes, plates, hexagons, pentagons, polarizing, non -polarizing (usually somewhere in between), narrowband, broadband, dielectric, air-spaced, metal, cemented, optically contacted (epoxy free bonding)... It is our job to help you sort out specifications that will meet your requirements for performance and cost.
Some of the key parameters to think about are; the wavelength range, polarization and physical size requirements. Also, if the beam splitter will be used inside an interferometer, you may need to consider path length and phase matching requirements. It is always good if you can explain how you will be using your beam splitter, it can really help us to define out your requirements.
Several types of cube beam splitter are available directly from our online catalog. However do not hesitate to contact us to help specify your custom beam splitter or fill out the beam splitter quote request form below.

MacNeille polarizer made for use in one of our own instruments/ The MacNeille polarizer splits the s and p polarizations with 99.95:1 ratio. These polarizers work over a broad wavelength range but only over a small range of input angles.
Note: the non-45 degree angle of the beam splitter |

P polarization is much more inclined to transmit at large angles (in the 45 degree range). The challenge for coating designers is to adjust the transmission of the two polarizations to meet the requirements of the beam splitter. For more information see our Optical Calculators . |
