853.75-0.75 OD6 Ultra Narrow Bandpass



853.75-0.75 OD6 Ultra Narrow Bandpass



Ultra Narrow filters bring new levels of performance to filters with very narrow bandwidth responses. Typically fully blocked to OD4 or OD6 and < 3 nm wide at FWHM, Alluxa Ultra Narrow Filters are uniquely steep and accurate. All Alluxa Ultra Narrow filters are fabricated with a proprietary durable, hard coating process. Even very narrow ( < 0.5 nm at FWHM ) Ultra Narrow filters typically have transmission values > 90%.
