High Transmission Bandpass Filter – Asahi Spectra

CWL 400-900nm, FWHM 10nm, Blocking range is up to 1100nm


Asahi Spectra improved and renewed the bandpass filters, the XBPA series. Magnetron sputtering technology replaces conventional bandpass filters with all dielectric coating design. We were successful in replacing conventional bandpass filters with high transmission bandpass by the state-of-the-art magnetron sputtering technology. Thanks to all dielectric coating design and a monolithic substrate, imaging quality is significantly improved as well as peak transmission. We release the center wavelengths, 400 nm - 900 nm this time.
