Beam radius
WebThe beam parameter product (BPP) is another metric used to evaluate the quality of a laser beam. It is defined as the product of the beam radius at the beam waist and the half-angle beam divergence. It is typically reported in mm mrad, and is related to the M 2 factor by: (5)BPP= M 2λ π BPP = M 2 λ π. Since the BPP is directly proportional ... WebW-Beam & Thrie-Beam Systems. Rail sections specified to be installed on curves having a radius of 5 feet (1.5 m) to 150 feet (45.7 m) can be curved in our fabrication facilities prior to delivery. Rail can be curved either convex or concave as required. Terms convex or concave refer to the direction curved, outward or inward, relative to the ...
