Blazed grating

A blazed grating is a specialized optical device that manipulates light by using closely spaced, precisely angled lines called grooves. Its main purpose is to efficiently direct specific wavelengths of light into a chosen direction, enhancing the brightness of particular colors or signals. The "blazed" design means the grooves are tilted at a specific angle to optimize this light dispersion, much like a finely cut mirror that favors reflecting certain wavelengths. Blazed gratings are widely used in spectrometers, lasers, and optical systems for precise wavelength separation and analysis.
