Schott Colour Glass Filters

UQG manufacture Schott Colour glass filters transmitting from the optical wavelengths range above 200nm. The filter glass is manufactured in different thicknesses which multiply the number of filter effects. By combining different filters together you can achieve additional filter effects. UQG Schott filters offers an entire palette of optical glass filters with long pass characteristics cut offs from the (UV) ultraviolet to the near (IR) infrared which include Longpass, Shortpass, Bandpass and Conversion Filters.
