Cylindrical Plano-concave Lenses BK7 Visible Coated 400-700nm
Out of stock
SKU
CLB-N-M
Cylindrical plano-concave lens has a concave curvature in the vertical direction and has no curvature in the horizontal direction. When used in combination with a plano-convex cylindrical lens an elliptical shaped beam can be sharped into a circular beam for use in semiconductor and other laser applications.
