Today, astronomers seek to observe the faintest and most distant objects possible. Extremely Large Telescopes (ELTs), with apertures in the order of several dozen meters, are the next generation ...
Far-infrared spectroscopy probes the cold and dust-enshrouded regions of the Universe by measuring electromagnetic radiation in the 30–300 μm band. This regime encompasses the principal cooling lines ...
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 ...
Cryogenic thermal control coatings represent a significant advancement over existing coatings limited to high reflectance in the 0.2–2.5 μm solar spectrum range, being able to reflect 96.6% of solar ...
Visual demonstration of the performance of the diffraction grating. The zeroth order transmission refers to light that goes straight through the grating without undergoing diffraction (which should be ...
