Alluxa Introduces Two Innovative Hydrogen Alpha (H-alpha) Emission Line Filters for Astronomy

a global leader in high-performance optical coatings, filters, and thin-film deposition technologies, announces the development of two groundbreaking Hydrogen Alpha (H-alpha) Emission Line Filters for astronomy applications. 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 a peak transmission of approximately 80% and is fully blocked to OD6 out of band (see graph below):

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%, as shown in the graph below:

Chief Commercial Officer Peter Egerton notes,

We are delighted to announce this innovation in ultra-narrow optical filters technology. Our engineering team has worked diligently on these breakthrough emission line filters, and we look forward to showcasing them at the upcoming SPIE Astronomical Telescopes + Instrumentation 2022 exhibition in Montreal.”

The company will premiere both H-alpha emission line filters at SPIE’s Astronomical Telescopes + Instrumentation Exhibition, Montreal, Quebec, July 19 – 21, 2022 in booth #405.
