We supply from ZnS, quartz, glass, silicon, and germanium in sizes up to 200mm diameter up to the half ball.
Hot-pressed ZnS domes are fabricated from ZnS, quartz, glass, silicon, and germanium in sizes up to 200mm diameter up to the half ball and dimensional tolerances to +/-10 microns. Parallels between the radii better than 20 microns.
All optical components may be coated according to function and requirements. Reflective or anti-reflective coatings, with high power damage threshold for laser industries, are available.
