-
Our products UV band pass filters ZWB1 ZWB2 ZWB3 are respectively equivalent to bandpass filter glass UG11, UG1, UG5 of Germany Schott and Ultraviolet transmitting visible absorbing filters U340, U360, U330 of Japan Hoya.
UV band-pass filter glass transmit the ultraviolet region but absorb the visible region.These filters are chiefly used for single extraction of ultraviolet rays. They are often utilized for selectively transmitting the 254nm and 365nm wavelengths, which are the representative line spectra of mercury lamps.
Main Application Inspection Device, Lighting System, Geological Survey, Non-destructive Testing, Medical Analysis Instruments such as UV Transilluminator, etc.
