Transmission lens is a kind of precision lens with high quality that is specially used in the interferometer measurement for the surface shape of the optical part and the wave front of the optical system.
Transmission spheres are used when measuring the surface quality or transmitted wavefront of concave or convex surfaces or optics. A concave or convex spherical surface is examined for surface figure and irregularity by placing its center of curvature coincident with the focus of the transmission sphere.
