Beamsplitters and Dichroic Filters

We manufacture a wide range of Beamsplitters and Dichroic Filters  specifically to your specification for both small and  large production volumes.

  • They can be used to separate different planes of polarisation.
  • Some examples of our previous work can be found below.
  • To discuss your specific requirements please contact us through the link below.
  • They are placed in optical systems usually at 45° to separate (or combine) different wavebands or wavelengths. One band is reflected from the front surface the 2nd band is transmitted through, see diagram below.
