Picture frame structure of heavy-calibre combined lens

Abstract

The invention discloses a picture frame structure of a heavy-calibre combined lens, which comprises a picture frame, a space ring, a gasket and a threaded ring, wherein regulating screw structures are additionally arranged on the picture frame. According to the invention, by using the symmetric regulating screw structures, the position of one lens in the combined lens is regulated, the processing requirement of center deviation of an optical element and the matching precision of a mechanical member are reduced, an optical system is more conveniently debugged, and an ideal imaging quality is reached. The picture frame structure can be widely applied to optical system debugging, system imaging and system detection of a heavy-calibre imaging system in optical engineering and optical experimental devices, and has strong practicability.

Description

technical field [0001] The invention relates to an optical imaging system, in particular to a frame structure of a large-diameter combined lens, which can be widely used in optical system debugging, system imaging and system detection of the large-diameter imaging system in optical engineering and optical experimental devices. Background technique [0002] The commonly used combined lens frame is an ordinary frame structure, simple in structure, easy to install, and does not need to adjust the lens, but its shortcomings are also obvious. If you want to obtain the theoretically designed imaging effect, the processing requirements of the optical lens are quite high. The center deviation of the components is small, and the matching precision of the mechanical parts is required to be high. Traditional small-aperture optical elements can meet their processing requirements through the process of coaxial hemming, but for large-aperture optical elements, it is very difficult to achi...
