1650.96-0.8 OD4 Ultraarrow Bandpass

Ultraarrow filters bringew levels of performance to filters with veryarrow bandwidth responses. Typically fully blocked to OD4 or OD6 and 3m wide at FWHM, Alluxa Ultraarrow Filters are uniquely steep and accurate. All Alluxa Ultraarrow filters are fabricated with a proprietary durable, hard coating process. Even veryarrow ( 0.5m at FWHM ) Ultraarrow filters typically have transmission values 90%.
