Bandpass filters marked with an asterisk* are in mint condition, sealed in an air-tight mylar package with desiccant with only the wavelength information recorded on the outside. Some have been opened and re-sealed to determine the FWHM values. These are nominally 1.5 nm - 10 nm. If you are in need of the FWHM value of a specific wavelength not yet measured, just ask and we can find that out for you.
