Embodiment Construction

[0035] Embodiments of the present invention are described in detail below, and the embodiments are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0036] Cassette optical system is an important part of the imaging device, and the quality of its adjustment affects the performance of the entire product. Due to the particularity of its structure, it is difficult to ensure the coaxiality of the main optical axis of the primary mirror and the secondary mirror and the optical distance between the primary mirror and the secondary mirror during the assembly and adjustment process, so that the assembly accuracy of the cassette optical system cannot meet The design requirements will affect the imaging quality in severe cases. This installation and adjustment method ensures the coaxiality and optical interval of the main optical axis of the primary mirror and the secondary mirror in the card-type optical system by ...

Abstract

The invention provides a card-type optical system installation and adjustment method and belongs to the ray machine installation and adjustment technology field. A card-type optical system is taken asthe important component of an imaging device, and installation and adjustment quality influences whole product performance. Because of the particularity of the structure, during an installation and adjustment process, the coaxiality of a main mirror and a secondary-mirror main optical axis, and the optical interval of the main mirror and the secondary mirror are difficult to guarantee so that theassembling precision of the card-type optical system can not satisfy a design requirement and even imaging quality is impacted. By using the installation and adjustment method, through using an installation and adjustment platform, an internal focusing light pipe, a standard ball and other devices, the coaxiality of the main mirror and the secondary-mirror main optical axis, and the optical interval in the card-type optical system are guaranteed, and the assembling efficiency and the quality of the card-type optical system are increased.

Description

technical field [0001] The invention belongs to the technical field of card-type optical system assembly and adjustment, and can effectively ensure the coaxiality of the main optical axis of the primary mirror and the secondary mirror in the card-type optical system, as well as the optical interval between the primary mirror and the secondary mirror, thereby ensuring the accuracy of the card-type optical system. image quality. Background technique [0002] Cassette optical system is a classic optical structure of imaging device, and the quality of its adjustment greatly affects the performance index of the entire optical system. [0003] Limited by the product structure, the assembly and adjustment of the cassette optical system is generally carried out by monitoring the resolution and surface shape of the final imaging with the help of an optical bench or interferometer. The equipment required for this assembly method is expensive and huge, not only It is time-consuming, a...
