Custom cylindrical convex mirrors for one-axis beam expansion and astigmatism control.
Product Overview
A cylindrical convex mirror has an outward-curved reflective surface with curvature in one direction and no curvature along the cylinder axis.
It increases beam divergence in the curved direction while adding no focusing power along the cylinder axis.
Substrate material, length, width, thickness, cylinder-axis orientation, radius of curvature, surface figure, and reflective coating can be specified from drawings.
Applications
- Laser Beam-Shaping Modules: Spreads a beam in one direction to adjust its width or aspect ratio.
- Reflective Anamorphic Beam Expanders: Works with a matching concave cylindrical mirror to expand a collimated beam along one axis.
- Astigmatism-Correction Modules: Adds diverging power in one direction to adjust the unequal convergence of the two beam axes.
