Ultra-narrow bandpass optical interference filter is a multi-cavity filter with moderately steep edges and a flat top. Alluxa ultra-narrow bandpass filters have the highest transmission and narrowest bandwidths currently available. And because they are hard-coated using our innovative SIRRUS? plasma deposition process, all Alluxa optical filters are highly durable and resistant to laser damage.
