High-end optical filters and beam splitters for flat optics

Light control with precision High-end optical filters and beam splitters

Filters and beam splitters are essential components of high-quality optical components. From fluorescence microscopy and spectroscopy to use in medical devices, they are used in many fields – with specific functions. Which ones these are can be controlled via various coating technologies. ZEISS offers you a wide range of processes with which we can equip your components with diverse and sophisticated properties. All the way to the variable filter with complex features that can fit into even the smallest installation space.

Circular variable filters

Due to their versatility, circular variable filters allow a much more compact device design. This innovative solution finds its application in, among others:

  • Fluorescence spectroscopy
  • Microscopy
  • Hyperspectral imaging
  • Compact spectrometry
High transmission in the pass band
High transmission in the pass band

High transmission in the pass band

The linear and circular variable filters have high transmission in the pass band (T> 95%), high blocking in the stop band, (OD > 4), high edge steepness (<3%) in the VIS and NIR spectral range.
