Multifunctional lens with collimation and coupling functions

Abstract

The invention discloses a multifunctional lens with collimation and coupling functions. The collimating lens and the coupling lens are both arranged between two stand columns. Second connecting platesare arranged on the side walls of the collimating lens and the coupling lens; the two second connecting plates are both rotationally connected with the left stand column. The connecting block is an iron-nickel alloy block; the connecting block is magnetically connected with the electromagnet; six color-changing LED shadowless lamps are arranged on the upper surface of a mounting plate at equal angle and correspond to positions of a placing plate, an adjustable resistor is arranged on the upper surface of the mounting plate, the output end of the adjustable resistor is electrically connected with the input end of the color-changing LED shadowless lamps, light can be collimated and coupled, the imaging effect is good, the distance between a specimen and a lens can be adjusted, the color ofa light source can also be adjusted, and the optimal imaging quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of lenses, in particular to a multifunctional lens with both collimation and coupling. Background technique [0002] A lens is an optical element made of a transparent material whose surface is part of a spherical surface. The lens is composed of several lenses. There are two types of plastic lenses and glass lenses. Glass lenses are more expensive than plastic. Usually, the lens structures used in cameras are: 1P, 2P, 1G1P, 1G2P, 2G2P, 4G, etc., the more lenses, the higher the cost. Therefore, a good-quality camera should use glass lenses, and its imaging effect is better than that of plastic lenses. It is used in astronomy, military, transportation, medicine, Fields such as art play an important role, and are often used for observation and imaging in the medical field; [0003] The existing application number is CN201320205062.7, which discloses a multifunctional lens for otorhinolaryngology head and neck...

[0003] The existing application number is CN201320205062.7, which discloses a multifunctional lens for otorhinolaryngology head and neck. Through the structural setting of the positive light group and the negative light group of the lens, the working distance is longer, which is convenient for operations such as picking up objects and operations. At the same time, the present invention By integrating the imaging device and the lighting device on the lens device, it is more convenient to use, more practical, and more functional. However, this arrangement cannot collimate and couple the light during imaging, and the imaging effect is not good. Moreover, the existing The lens has no adjustment function, the distance between the specimen and the lens cannot be adjusted, and the color of the light source cannot be adjusted, so the best imaging quality cannot be guaranteed.
