Optical color glass is also called color filter glass. It is mainly used as filters for observing,photograph,infrared instrument  in order to improve the visibility or meet special spectrum requirements. It can be also made into colored glasses.

Worldhawk can provide precision filters for many applications, including bandpass interference filter, Cut off filters, UV bandpass filter, Narrow bandpass filter, ND filter, Negative Filter or Notch filters, dichroic, color substrate.     

Optical Filters are used to selectively transmit or reject a wavelength or range of wavelengths. Optical Filters are used in applications such as fluorescence microscopy, clinical chemistry, spectroscopy, or machine vision inspection. Optical Filters are ideal for life science, imaging, industrial, or defense industries.
