施密特摄星仪是一种设计用于广视野但像差很小的天文照相机。其他相似的设计有赖特摄星仪和Lurie-Houghton望远镜。

施密特摄星仪是伯恩哈德·施密特在1930年发明的 。他的光学构造是以易于磨制的球面镜做主镜,和位于主镜曲线前方的非球面镜的修正透镜,也就是熟知的修正板,底片或其他的检测设备安置在摄星仪内部的焦点上。在设计上都允许快速的焦比和控制住彗形像差和球面像差。

施密特摄星仪的焦平面有很明显的弧度(曲率),因此使用的底片、干版、或其他的检测器都必须有相对应的弧度。在某些情况下,检测器被制作出弯曲的弧度,在其他平面的媒介上则依据焦平面的形状使用螺栓或固定夹来调整,或是应用真空牵引。有时也会使用平场,-以他最简单的形式,以一个平凸透镜直接紧贴着底片。使用这种透镜的称为施密特-维萨拉摄星仪。

One of the Baker-Nunn cameras used by the Smithsonian satellite-tracking program.

A Schmidt camera, also referred to as the Schmidt telescope, is a catadioptric astrophotographic telescope designed to provide wide fields of view with limited aberrations. The design was invented by Bernhard Schmidt in 1930.

Some notable examples are the Samuel Oschin telescope (formerly Palomar Schmidt), the UK Schmidt Telescope and the ESO Schmidt; these provided the major source of all-sky photographic imaging from 1950 until 2000, when electronic detectors took over. A recent example is the Kepler spacecraft exoplanet finder.
