Problems solved by technology

When these two kinds of optical lenses are applied to the optical imaging experiment, there are the following problems: (1) the rotating wheel adjustment aperture lens cannot directly adjust the distance between the main plane of the optical imaging lens and the photosensitive surface of the imaging detector, so focusing cannot be achieved; (2) ) lever to adjust the aperture lens can neither directly achieve focus nor directly adjust the aperture size

Abstract

The invention relates to a lens focusing and aperture adjusting imaging device. The device comprises an optical lens, an adjustment component, a focusing sleeve, a fixing plate, a metal box, a drivingcircuit board and an imaging detector. The adjustment component is provided with a boss structure and is used for rotatably fastening and connecting with the groove structure of the optical lens. Theinternal thread of the focusing sleeve is cooperated with the external thread of an aperture adjusting component so as to carry out adjusting and focusing. The fixing plate and the metal box are connected through four bolts so as to be used for fixing the focusing sleeve. The driving circuit board is used for driving the imaging detector. Compared with the prior art, by using the device of the invention, the aperture size of the optical lens can be adjusted, and lens focusing can be realized; and the structure is simple, dismounting is convenient, manufacturing cost is low and the device is stable and reliable.

Description

technical field [0001] The invention belongs to the technical field of photoelectric imaging, and in particular relates to a lens focusing and aperture adjusting imaging device. Background technique [0002] At present, the existing imaging lenses are divided into lenses for adjusting the aperture with a lever and lenses for adjusting the aperture with a rotary wheel according to their functions. Adjusting the aperture of the lens with the lever The aperture of the lens can be adjusted by turning the lever, and the aperture of the lens can be adjusted through the aperture adjustment wheel. When these two kinds of optical lenses are applied to the optical imaging experiment, there are the following problems: (1) the rotating wheel adjustment aperture lens cannot directly adjust the distance between the main plane of the optical imaging lens and the photosensitive surface of the imaging detector, so focusing cannot be achieved; (2) ) lever to adjust the aperture lens can neit...
