Optical Filters
Optical filters transmits a desired wavelength interval while simultaneously attenuating all other wavelengths in the range of UV (200nm) to IR(1100nm). They find application in a host of fields such as clinicalchemistry, environmental testing, colorimetry, elemental and laser line separation, flame photometry, fluorescence, astronomy, etc. There are very few companies in the world who make these high tech optical components.
