Hydrogen alpha filters for astronomy, spectroscopy, plasma monitoring, and fusion introduced by Alluxa

SANTA ROSA, Calif. – Alluxa Inc. in Santa Rosa, Calif., is introducing the two electro-optical hydrogen alpha (H-alpha) emission line filters for astronomy applications.

These filters are tailored to monitor H-alpha spectra in astronomy, and also can be used in applications where spectral line discrimination is critical, such as spectroscopy, plasma monitoring, and fusion research.

The filters have a 50 percent BW of 0.35 nanometers, a 1 percent BW of less than 0.6 nanometers, a peak transmission of approximately 80 percent and is blocked to OD6 out of band.

Alluxa's cavity H-alpha filters features a narrow design with a FWHM of 0.12 nanometers and peak transmission of greater than 90 percent.
