Abstract

The invention discloses an adjusting method and device for an off-axis reflecting type optical system. Simple and rapid adjustment of an optical path of the off-axis reflecting type optical system canbe achieved through an interval adjusting device composed of four plane reflectors. For a telescope system composed of two off-axis parabolic mirrors, the device is mainly composed of a light source,a diaphragm, a primary mirror, an interval adjusting device, a secondary mirror, an exit pupil, a shear plate and an observation surface. One simple implementation mode of the interval adjusting device is that the interval adjusting device comprises four plane mirrors, a support and a guide rail, a first plane mirror is parallel to a second plane mirror, and a third plane mirror is parallel to afourth plane mirror. The four plane mirrors are installed on the guide rail through the support and can move. The adjusting device used in the invention is simple in structure and convenient to adjust, can solve the problem that the optical path of the off-axis reflecting type optical system is complex and difficult to adjust, and is expected to be applied to various off-axis optical systems needing to be adjusted.

Description

technical field [0001] The invention relates to the technical field of off-axis reflective optical systems, in particular to an adjustment method and device for off-axis reflective optical systems, which can be used for fast and accurate adjustment of the optical path of off-axis reflective optical systems. Background technique [0002] The off-axis reflective optical system has the characteristics of wide operating band, small loss of light energy, and no chromatic aberration. At the same time, it can meet the requirements of some optical systems for no obstruction, so it is widely used. [0003] The currently commonly used method for adjusting the optical path of an off-axis reflective optical system requires the design of a complex adjustment device for the off-axis reflector to control the off-axis reflector to achieve multi-dimensional adjustment. Complicated adjustment devices will not only increase the complexity of the optical system, but also increase the instabilit...
