Profile: Optometrics Corporation is a supplier of optical components and instruments. Our products include filters, diffraction gratings, monochromators and systems, IR laser optics, SPF analyzer, beam splitters & tunable light sources. Our interference bandpass filters are wavelength selectors that allow transmission of a predetermined wavelength when rejecting or blocking other wavelengths. Interference filters are used in instrumentation for clinical chemistry, environmental testing, colorimetry, elemental and laser line separation, flame photometry, fluorescence & immunoassays. It produces thousands of filters specified by and designed for other instrument manufacturers. Our tunable light sources are used to illuminate materials with only a small range of wave-lengths. They are used to study wavelength dependent chemical, biological and physical changes or properties. This source is used in color analysis and reflectivity measurements of products for aesthetic purposes.
