Wavefront distortion - main performance parameters of optical device

the technical requirements of optical component mainly include: parallelism flatness transmitted wavefront distortion and surface quality, etc. Most of the optical element manufacturersare focused  on parallelism, flatness and surface quality. In fact, the wavefront distortion plays a very important role on the performance of the optical device, Because wavefront distortion is comprehensive reflection of material quality and surface processing quality. Under the condition of ideal wavefront distortion, light passed through the optical device, the optical path difference of each beam of light is equal. At that time, energy loss and the waveform distortion at the space are minimum. When processing optical device, through to the improvement of wavefront aberration, can eliminate the internal stress of the material, reduce unnecessary stress birefringence. The optical device will show very good performance in working.
