Concave Mirror, Copper, MMR-P, 50 mm Diameter, 10 mm Edge, 6.7MCC, Bystronic
The 632645-117 concave mirror is 1.97 inch (50 mm) diameter with a 10.0 mm edge thickness, 6.7MCC curviture, and is Bystronic OEM compatible. These MMR-P coated copper telescopic mirrors are used to increase the beam diameter.
In many applications, the small diameter of the laser beam produced in the laser cavity is not convenient because the beam has high divergence and high power density. In order to avoid subsequent problems, the beam diameter can be increased by using a telescope consisting of two mirrors, one with a convex surface and the other with a concave surface.
