Quarter-wave window coatings from Edmund Industrial Optics reduce reflections and distortions in laser and electronic imaging applications. The units have a maximum peak-to-valley surface roughness of approximately 150 nm and have parallel surfaces to 1 arc min. The windows are available with diameters that range from 5 to 50 mm and thicknesses of 2, 3 or 4 mm. They are fabricated from BK 7 grade A fine annealed glass with a 60-40 surface quality.
