Anamorphic Prism Pairs are used to transform elliptical laser diode beams into nearly circular beams. Because the prisms are set near Brewster's angle and with AR coating customized to the angle of the index SF11 glass, an average throughput of 95% can be achieved. Specifications: Material:N-SF11 Size Tolerance:+/-0.05mm CA 80% Flatness: 1/4 lambda
