Schmidt telescope with external image capture

摘要

A telescope system may facilitate the capture of images of light, and may have a housing, a primary mirror, a Schmidt corrector plate, and a lens group. The housing may have a mirror end and an aperture end with an entrance aperture that receives the light. The primary mirror may be positioned proximate the mirror end, and may have a spherical shape. The Schmidt corrector plate may be positioned proximate the entrance aperture to direct the light toward the primary mirror in a manner that substantially compensates for the spherical shape. The lens group may include multiple lenses, one or more of which may be positioned within the housing proximate the aperture end such that the light is directed through the lens group by the primary mirror. The lens group may focus the light at a focal location further than the Schmidt corrector plate from the primary mirror.

主权项

1. A telescope system for facilitating capture of images of light, the telescope system comprising:
a housing comprising a mirror end and an aperture end comprising an entrance aperture through which the light enters the housing; a primary mirror positioned within the housing, proximate the mirror end, the primary mirror having a spherical shape; a corrector plate positioned within the housing, proximate the entrance aperture, wherein the corrector plate is shaped to direct the light toward the primary mirror in a manner that substantially compensates for the spherical shape of the primary mirror, the corrector plate having a passageway; and a lens group comprising a plurality of lenses, all of which are positioned within the housing between the corrector plate and the primary mirror, proximate the aperture end, wherein the lens group is positioned and configured such that light is directed through the lens group by the primary mirror, and is focused at a focal location further than the corrector plate from the primary mirror; wherein at least one lens of the lens group has a dimension larger than the size of the passageway in the corrector plate.
