Optical and Electro-Optical Components

Optical components made of glass or crystalline materials are extremely numerous in terms of design, material and diversity of application. Optical materials can be broken down into four, main categories:

Glass Materials

  • Optical Glass
  • Laser Glass
  • Color Filter Glass
  • Technical Glass

Low Expansion Materials

  • Fused Silica & Quartz
  • Crystal Quartz
  • Mirror Substrate Materials

Optical Crystals

  • UV Crystals
  • IR Materials
  • Laser Crystals
  • Hygroscopic Crystals

Miscellaneous Materials

  • Optical Plastics
  • Ceramics
  • Metals

Chemetall Precision Microchemicals develops and manufactures a wide range of coolants, lubricants, abrasive slurries, polishing pads and cleaners associated with all optical fabrication steps such as shaping, milling, loose abrasive grinding/lapping and polishing. Our diamond and non-superabrasive abrasive slurries including alumina, ceria, zirconia, silica, boron carbide and silicon carbide are stringently graded and dispersed to enable the production of optically "perfect" surfaces with minimal sub-surface damage.

Optical Fabrication Engineers, R&D and Production Staff are encouraged to contact Chemetall Precision Microchemicals for detailed technical information.
