Alluxa introduces two Hydrogen Alpha (H-Alpha) Emission Line Filters

11 Aug 2022

Alluxa introduces two Hydrogen Alpha (H-Alpha) Emission Line Filters that are revolutionizing the ultra-narrow optical filters market. Though these new filters have been specifically tailored to monitor H-alpha spectra in astronomy, they can also be used in any application where spectral line discrimination is critical, including spectroscopy, plasma monitoring, fusion research, and more.

The novel 5 Cavity H-alpha Filter sets a new standard for narrow filters with regard to squareness. It has a 50% BW of only 0.35 nm, a 1% BW of <0.6 nm, and peak transmission of approximately 80% and is fully blocked to OD6 out of band. 

Alluxa’s 2 Cavity H-alpha Filter features an even narrower design with a FWHM of 0.12 nm and peak transmission of greater than 90%.

Chief Commercial Officer Peter Egerton notes, “Our engineering team has worked diligently on these breakthrough emission line filters. We are delighted to announce this innovation in ultra-narrow optical filters technology.”
