Abstract
In recent years, requirements such as over-the-horizon, high resolution, large field of view, wide spectrum and dexterity have pointed out new directions for the development of optical imaging systems. Common optical surfaces such as planes and spherical surfaces have been difficult to meet the requirements of optical indicators. It is often necessary to use multiple high-precision complex optical surfaces such as high-order aspherical surfaces, off-axis aspherical surfaces, non-rotational symmetric curved surfaces, microstructured optical array surfaces and freeform surfaces. This brings processing, testing and adjustment in terms of problems, the monolithic multisurface optics as a new type of optical element are increasingly attracting researchers' attention.
