Science today demands creative equipment designs to provide a range of environmental conditions for samples during analysis.  Liquid and gas cells used for spectroscopic analysis of materials under controlled environment consist of two windows with well-defined spacing. While quartz is the common window material for visible wavelengths, diamond is the ideal choice for the infrared or terahertz spectral range. Diamond’s broadband transparency, extreme chemical inertness and unsurpassed hardness greatly extends the range of materials that may be analyzed.

By preparing a well-defined thickness variation (wedge) during polishing, interference oscillations are successfully suppressed.  Conical surfaces allow insertion into continuous process streams or increased contact area with solids.  Brazing of windows into a number of alloys ease the tailoring of corrosion and thermal properties to your experimental environment.
