Thorlabs' Mounted Bandpass Colored Glass Filters are manufactured from different colors of Schott® glass and are intended for use in a wide variety of applications. The SM1-mounted (1.035"-40), Ø25 mm filters will thread into our manual or motorized filter wheels or any of our lens tube accessories. The housing is engraved with the Item # and intended wavelength range for easy identification. If the bandpass filter you require is not listed here, it may be available in an unmounted version.
Several of the colored glasses used for our filters are fluorescent at certain wavelengths; for more details on how this may affect certain applications, contact Technical Support. For narrowband sources, we recommend our dielectric bandpass filters.
