HOMOSIL 101 and HERASIL 102
HOMOSIL 101 and HERASIL 102 are optical quartzglass grades manufactured by flame fusion of cultured quartz crystals. They combine excellent physical properties with outstanding optical characteristics from the UV to the IR . The index homogeneity is controlled and specified either in one direction (the direction of use or functional direction) or even in all three dimensions.
HOMOSIL 101 and HERASIL 102 meet the requirements for bubble class 0 and are practically free of inclusions.
The optical homogeneity, which is the main criterion for very low transmitted wavefront distortion, refers to two categories:
  • HOMOSIL 101 is an optically isotropic 3D-material. It is highly homogeneous and has no striations in all three dimensions. These properties are very important for multiple axis optics such as prisms, steep lenses, beam splitters, etalons or retroreflectors.
  • HERASIL 102 is homogeneous in the primary functional direction. Weak striations, if any, are parallel to the major faces and do not affect the optical performance. HERASIL 102 is the preferred material for demanding optics in one directional use such as lenses, UV-laser windows, optical flats.

HERASIL 3
HERASIL 3 is a cost effective preferred material for simple technical optics-components having a good homogeneity even under difficult environmental conditions such as high temperatures, temperature-shocks, chemically agressive media, pressure load.

HOQ 310
HOQ 310 is manufactured by fusion of natural quartz crystals in an electrically heated furnace.
HOQ 310 is economically priced and has been developed especially for applications in the technical optics field. Compared with "typical" optical glasses it provides a unique combination of attractive properties:
  • Excellent optical transmission from the UV into the IR spectral region.
  • Outstanding high temperature resistance.
  • Extremely low coefficient of thermal expansion.
  • Superior temperature shock resistance.
  • Excellent chemical resistance.
  • Outstanding chemical purity.
Combined with a low bubble content and an attractive price HOQ 310 is the preferred material for lower precision optical applications in a hostile environment, e.g. high temperature and/or thermal shock loads, pressure loads, chemically aggressive atmosphere, etc., such as inspection and/or illumination windows, cover plates, windows for pressurized cabins, etc.
