1. Filter fluorometers produce specific excitation and emission wavelengths by using optical filters . 2. Thin films are used commercially in anti-reflection coatings, mirrors, and optical filters . 3. In filter photometers, optical filters are used to give the monochromatic light. 4. Thin films have many commercial applications including anti-reflection coatings, mirrors, and optical filters . 5. The article on optical filters has material relevant to photographic filters. 6. Optical filters are used to combine and split optical wavelengths onto the single fiber.7. One familiar example is the polarizer, an optical filter that transmits only one polarization. 8. By changing the optical filter , different substances can be measured. 9. Applications include Fabry P�rot interferometers, antireflection coatings, and optical filters . 10. Optical filters are used to select different wavelengths of light.
