Problems solved by technology

(such as Zhang Qing, "Convex lens that strictly focuses parallel light on one point", Journal of Anhui University of Technology, Vol.18, No.2, 2001: 170-172; Born and Wolf, "Principles of Optics: Electromagnetic Theory of Propagation, Interference and Diffraction of Light, Seventh (Expanded) Edition", CambridgeUniversity Press, 1999) The problem with this method is: on the one hand, the structure of the entire optical lens system is relatively complicated; on the other hand, because the inherent aberration of the lens is difficult to eliminate, often It is difficult to obtain high-quality tiny light spots designed theoretically

Embodiment Construction

[0007] The present invention will be described in further detail below. Referring to Fig. 1, the optical lens of the present invention is characterized in that it consists of fastening screw 4, lens barrel 5, aspheric reflector 6, aperture 7, spherical reflector 8, spherical reflector fastening screw 9, adjustment pad Composition of 10 tablets.

[0008] The lens barrel 5 is the carrier of the entire lens, and it is composed of a disc 5a, a ring 5b integrally connected with the peripheral edge of the disc 5a, and a central axis 5c located at the center of the disc 5a and integrally connected with the disc 5a . At the center of the disk 5a, there is a circular entrance pupil [1] concentric with the disk 5a, consisting of 3 to 6 circular arc through-slots evenly distributed along the circumference. The small arc diameter r of the circular-arc through-slot is greater than Equal to the diameter of the central axis 5c, the large arc diameter of the arc through groove R=r+t, t is t...

Abstract

This invention relates to one spot light source focus imaging optical lens head in optical technique and relates to one light source focus imaging optical lens improvement, which is characterized by the following: it comprises tighten screw nail, lens cylinder, non-sphere reflection lens, diaphragm, sphere reflection lens, sphere reflection lens tighten screw nail and adjust pad. This invention totally adopts reflection optical elements and uses non-sphere optical design technique to eliminate lens set bias to get micro spot size with high quality.

Description

technical field [0001] The invention belongs to the optical technology and relates to the improvement of an optical lens used for point light source convergence imaging. Background technique [0002] Tiny light spots have unique applications in the field of photoelectric testing, such as the detection of CCD sensitive elements, the detection of infrared detector array elements, the performance test of CPT electron guns, and the astral positioning of celestial sensors. Tiny light spots are usually obtained by converging and imaging the light emitted by a point light source by a specially designed optical lens system. At present, collimator light tubes are used both at home and abroad. First, the beam light emitted by the point light source is turned into parallel light, and then the parallel light is converged by a converging lens group to obtain a tiny light spot. (such as Zhang Qing, "Convex lens that strictly focuses parallel light on one point", Journal of Anhui Universi...
