Guide Light Beams With Beam Splitters and Filters

By coating a material with a filter or beam splitter, you can adapt a light beam.

Filters and Beam Splitters
If you want to split a light beam into segments of differing intensities, or into different wavelength ranges, then you need a filter or beam splitter. This will allow you to couple out parts of the signal in the light beam, add extra information to light paths, suppress specific light components or separate excitation and detection waves.

Jenoptik enables optical components to be coated directly with a dielectric beam splitter or filter, saving you money for additional components and helping you to achieve high-quality results. If necessary, you can combine the coating with antireflection. The experts at Jenoptik have a precise understanding of the special requirements of polymers in the coating process. That's why the material is coated at low temperatures with adjusted plasma density and regularly undergoes climate testing and spectral measurements.


  • Precise: Plasma ion-assisted coating processes (APS plasma IAD)
  • Robust: Coating at low temperatures with adjusted plasma density
  • Effective: Filter and beam splitters are integrated into the system
  • Flexible: Can be combined with antireflection coatings
  • Tested: Series climate testing for quality assurance

Fields of Application
