We have the capability to research and develop the Cassegrain Reflector System with medium size (Aperture＜φ600mm）. The typical indexes reach or exceed the wavefront aberration better than PV λ/6，RMS λ/40（λ=632.8nm）. We also can develop metal cassegrain reflector system in light weight which covers aperture from 30mm to 600mm.
