At ICL, we have been producing high quality crystal optics for use in infrared spectrometers, accessories, and other analytical devices since 1962. We are the only U.S. company that produces KBr crystal, a standard component of infrared spectrometers. We are also one of the few companes in the world that grows potassium bromide optical crystals.  In house, we also produce the materials for other vital crystal optics such as KCl, NaCl, AgBr, AgCl, CdMnTe, and more. We also stock a large variety of spectroscopy optics made from other essentials like CaF2, BaF2, ZnS, ZnSe, Si, BK-7, etc. Circular Discs and Rectangles  are available in all of the common sizes, typically in the range of 20mm-50mm (for use as windows common to infrared sample cells and accessories). However, we offer a large range of sizes for various applications, from tiny plugs for microscope slides to large aperture optical viewports (100mm in diameter or more).
