Microscopic light path laser coupling repeated positioning device

Abstract

The invention discloses a microscopic light path laser coupling repeated positioning device. The device comprise an upper glasses frame (10) and a base (20) which are arranged up and down, three balls(30) are arranged between the upper mirror bracket (10) and the base (20); three upper grooves are formed in the upper surface of the base (20); the three upper grooves are distributed in a triangular shape; the bottom surface of the first upper groove (21) is a conical surface; the bottom face of the second upper groove (22) is a V-shaped face, the bottom face of the third upper groove (23) is aplane, three lower grooves are formed in the lower surface of the upper mirror frame (10), the upper portions of the balls (30) are located in the lower grooves, the lower portions of the balls (30)are located in the upper grooves, and the centers of the three balls (30) are located in the same reference plane. The microscopic light path laser coupling repeated positioning device not only can realize high-repeatability microscopic light path laser coupling, but also can facilitate subsequent expansion and increase of a laser light path.

Description

technical field [0001] The invention relates to the field of optical equipment, in particular to a microscopic optical path laser coupling repeat positioning device. Background technique [0002] In micro-laser test equipment, such as micro-Raman, micro-fluorescence and other test systems, multiple lasers need to be configured, and different optical filters are required to couple the laser light path to the micro-light path, such as figure 1 As shown, it contains a detector 1, a laser 2, a microscopic illumination 3, a sample 4, a microscope 5, a camera 6, a laser coupling filter 7, a spectrometer coupling optical path 8 and a spectrometer 9. [0003] When switching the laser, it is necessary to switch the corresponding optical filter. If the installation and repeat positioning accuracy of the optical filter is not good, it will seriously affect the laser light path in the microscopic light path. In severe cases, the laser will not be able to pass through the microscope. Th...

AI Technical Summary

Problems solved by technology

[0005] The disadvantage of using the turntable to switch the optical filter to switch the laser light path is that if the design of the turntable is finalized, the number of filter components installed on the turntable will also be determined. Therefore, the number of laser light paths that can be coupled is also determined. It is determined that if it is necessary to expand and increase the laser light path in the future, it will not be possible

In addition, the technical solution of using the turntable requires the use of a high-precision turntable, and its cost is relatively high
