Abstract

The invention discloses a dual-focusing fine tracking lens comprising a lens focusing motor assembly (16), a primary mirror group (1) and a secondary mirror focusing assembly (2). The secondary mirrorfocusing assembly (2) comprises a second secondary mirror connection seat (215), a piezoelectric ceramic component, and a secondary mirror (201) fixed to the second secondary mirror connection seat (215). The piezoelectric ceramic component and the second secondary mirror connection seat (215) are connected to each other. The lens focusing motor assembly (16) includes a lens tube (1601) having afront group lens (4) therein, a focusing lens tube (1602), a long positioning screw (1605) connecting and fixing the lens tube (1601) and the focusing lens tube (1602), and a focusing motor (1608). Afocusing curve groove and a focusing gear meshed with the focusing motor (1608) are disposed on the focusing lens tube (1602). The dual-focusing fine tracking lens of the invention focuses the secondary mirror and the front group lens and achieves high-quality imaging.

Description

technical field [0001] The invention belongs to the technical field of optoelectronic equipment, and more specifically relates to a double-focus fine tracking lens. Background technique [0002] TV imaging technology is widely used in the fields of TV guidance and photoelectric reconnaissance. The TV imaging system includes optical system, receiving sensor, transmission path, processing and display, etc. In the process of informatization development, various TV imaging systems have been paid more and more attention by people because of their unique advantages. The television imaging system can be used alone or loaded on other carriers. When installed on other carriers, its optical axis is often required to be parallel to the carrier's large system datum. [0003] Specifically, the parallelism adjustment is to adjust the azimuth and pitch angle of the optical axis of the TV imaging system relative to the large system reference. Adjust the parallelism of the optical axis re...
