search

Reference number: OSE-CLB-1010-15NIR2

The cylindrical plano-concave lens has a concave curvature in vertical direction and no curvature in horizontal direction. In combination with a plano-convex cylindrical lens, an elliptically shaped beam can be formed into a circular beam for use in semiconductor and other laser applications.
