Rainbow Optics Does Optical Coatings

Optical coatings can be used to enhance or reduce the reflectance, transmittance, or polarization properties of optical components. Rainbow Research Optics offers a wide variety of standard coatings for the optics listed within our Products Guide. They include narrow-band and broad-band AR coating, full and partial reflectors, filters, as well as beam splitter coatings. Most of our products are available either coated or uncoated, and if coated, we can provide either standard or custom coating designs. Our coating equipment includes resistance heated and electron beam evaporation sources, making possible the use of ranges from the ultra-violet to the far infra-red wavelengths of light.   Visit our website today at and call with any questions at 303-371-3000.
