HOD® fused silica diffusor

New synthetic opaque fused silica for your optical applications.

Heraeus has developed a new opaque material, HOD®, which is a synthetic fused silica diffuser. This material can be used as a diffuser for several optical and industrial applications and is being used in space applications.

In contrast to other modern diffuser materials, HOD® offers different advantages, which we have compiled for you in the following.

Please also find information about application areas of HOD® and downloads with further information.

Please feel free contact our experts for additional questions.

HOD® can be used in several applications and provides smart answers to all your challenges. Benefit from a wide range of benefits:

  • excellent diffuse reflection and transmission with all the advantages of transparent fused silica
  • broad and diffuse reflection from UV to IR (with the exception of OH-absorption bands)
  • highly chemically inert, that means HOD® can also be used in the harshest environments
  • machinable
  • easy and quick cleaning with e.g. standard ultra sonic processes (no open porosity)

Furthermore, HOD® can be made highly resistant to UV radiation, thanks to a special process step developed by Heraeus.

HOD® is suitable for several applications. Please find below some examples:

  • in photometry, for example, to make a detector more sensitive in covering a large spatial angle
  • for the deliberate diffusion of strong light sources (such as lasers) to measure power
  • for the homogenization of point light sources (such as LEDs)
  • as cladding for integrating spheres in optical measuring technology
  • for calibration of spectrometers
  • as white balance in photography

The new material is already being used in space applications for remote sensing in satellites.
