Rising Color Temperature Glass SSB Series
Our Products Rising color temperature filter glass SSB40-200 are respectively equivalent to bandpass filters FG6, BG34, FG3 of Germany Schott and optical glass LB40-200 of Japan Hoya.
The color temperature glass, also called light balancing filter glass, is selective absorption glass which include rising color temperature glass and decreasing color temperature filter glass, and its transformation ability is expressed by the Mired value. The color temperature rising glass is blue, the grade is SSB. During production, R&D people usually adjust the thickness of filter glass to achieve the special mired value that required.
Main Application: Camera Lens, Inspection Device, Optical Instruments.
