Ultra Narrow Bandpass Filters
Ultra Narrow Bandpass Filters are ideal for use as laser line, laser cleanup, or laser excitation filters in demanding medical and laser applications. These hard coated filters are manufactured with state of the art plasma deposition processes, which ensure high resistance to laser damage and a high level of performance over a long period of time. Depending on the wavelength range and system requirements, these Ultra Narrow Bandpass Filters will provide up to 98% peak transmission, up to OD 10 blocking by design, center wavelength tolerances as tight a 0.05nm, FWHM bandwidths <1nm, and extremely steep edges with an ultra-flat passband profile. Typical applications include fluorescence microscopy, flow cytometry, and real time PCR or DNA sequencing.
