Optical filter flatness
WebOptical windows are flat plates made of optically transparent material, designed to allow light into an optical instrument. They can also be used to protect a light source from an outside environment. These windows are designed to minimize both reflection and absorption while maximizing transmission over a target wavelength range. WebMar 14, 2024 · Consider for a moment that if an optical flatness is specified as 1/10 wave at 632.8nm, it follows that the largest distance between the greatest peak and valley on a surface can be no more than 63.28nm while …
