BlazeLittrowEchelle

What is it about?

BlazeLittrowEchelle is a handy toolkit for building and tuning spectrometers. It helps you pick the blaze setting that gives the most light at your target wavelength. You can find the Littrow angle fast, keeping your setup small and efficient. It checks when diffraction orders overlap and tells you if you need an order-sorting filter. Change a slit width and see right away how the line shape, resolution, and SNR will shift. It converts groove density units and shows how input angle affects the output beam. You’ll get spot size in pixels on your detector and a clear view of what the camera will sample. For echelle work, it maps usable orders, links spectral range to detector size, and converts air↔vacuum wavelengths.
