GCC-40 Beamsplitter Cubes


The beamsplitter cube consists by a pair of precision right-angle prisms carefully cemented together to minimize wavefront distortion. The hypotenuse of one prism is coated with a multilayer beamsplitter coating which is specially designed according to the application. The four outside surfaces of the prism are AR coated with "V" type or broadband coatings to minimize surface reflection losses over the specific wavelength range.

GCC-401 Conventional Beamsplitter Cubes

This is a conventional energy beamsplitter independent of polarization. The incoming light should be one of the following: 45° linearly polarized, circularly polarized and natural light, i.e. the s-polarized and p-polarized components should be matched to within 5% of each other. The outgoing beams are two partially polarized beams of about equal intensities.

GCC-402 Polarization Beamsplitter Cubes

A polarizing cube beamsplitter consists of a pair of right angle prisms cemented together. The hypotenuse face of one prism is coated with a special multilayer dielectric coating. When nonpolarized light is normally incident upon the entrance face, it is separated into two polarized beams, emerging through two adjacent faces in perpendicular directions and polarized orthogonally to each other. The transmitted beam is p-polarized while the reflected beam is s-polarized. When the linearly polarized light is incident, it is similarly divided into two beams with the irradiance ratio depending upon the orientation of the electric field vector of the incident light beam. These polarizing beamsplitters are available for many common laser wavelengths and broadband ranges.

GCC-403 Non-polarizing Beamsplitter Cubes

  • Insensitive to Polarization
  • Laser Line and Broadband available

These cubes split energy only, having minimal polarization sensitivity, i.e. the polarization states are about the same for the entrance and exit beams. The p- polarized and s-polarized components for the incoming beams should be matched to within 5% of each other. Generally the incoming light is natural light, circularly polarized light or linearly polarized light with the polarization at 45°.

By cementing a wedge on surface S1 with a partially reflective coating, the penta prism can be used as a conventional beamsplitter. The T/R ratio is 50/50 for off-the-shelf products. Other ratios are available upon request.
