The Wedge Prisms, delicately manufactured by Altechna, functions through diverting light towards its relatively thicker portion. Through determining the appropriate wedge, it is very much simple to produce a precise beam deviation even without affecting the other beam parameters. In instances wherein two edges are utilized together in near proximity, it is entirely probable to come up with a constant variation of beam deviation by counter-rotating the wedges.
This product, made from a BK7-UVFS material, specially features a dimensional tolerance of about +0/-0.02mm with a 90% clear aperture. Additionally, the wedge tolerance of this prism is +/3 arcmin while its surface quality is 40-20 S-D.
