Colored glass filters find many uses in optical systems including imaging, laser, and industrial equipment. We describe design and fabrication techniques for implementing low cost optical filters which are an excellent choice for production systems. Filter glass remains an economic alternative to thin-film coated filters as they can produced in high volumes with no secondary operations. Calibrated filters can be produced for demanding applications and various material is available such that bandpass, short, or longpass filters can be tailored to the application. Opticology produces finished colored filter glass parts in any shape or size from commercial to precision quality. We offer free design assistance or can build parts to print.
