Graded Reflectivity Laser Mirrors
Created on Tuesday, 14 June 2011
A new series of graded reflectivity mirrors from REO (Boulder, CO) enables
precise spatial shaping of both the intensity and phase characteristics of
laser beams. In graded reflectivity mirrors, the reflectivity and/or phase
effects of the coating vary radially across the surface of the optic. REO
offers these graded reflectivity mirrors on a wide range of substrates
including fused silica, various optical glasses, ZnSe, ZnS and Si, for
operation over the 266nm to 5µm spectral range. These mirrors are available
with diameters from 0.25 inches (6mm) to 5 inches (127mm). Reflectivity
pattern variations can be achieved down to a scale of approximately 1mm.
