High quality Superachromatic Waveplate supply by CRYSMIT OPTICS
Time：2018-06-22 10:51
Crysmit' Superachromatic Waveplates offer extremely flat quarter-wave or half-wave retardance over a broadband range of 600 - 2700 nm.
Based on the design by Crysmit engineer, each consists of three quartz and three magnesium fluoride (MgF2) plates that are optically cemented to maximize transmission and carefully aligned to minimize the wavelength dependence of the retardance. Compared to other wave plates, superachromatic wave plates offer significantly flatter retardance over a significantly broader range. The plots to the right compare them to achromatic wave plates, the closest equivalent optics.
