Technical Field
[0001] The utility model relates to the technical field of lasers, in particular to a VCSEL or LED emitting device with small-angle focusing. Background Art
[0002] VCSEL is a special type of laser whose working principle involves the movement of electrons in the vertical direction rather than the horizontal direction. Small-angle focusing VCSEL usually refers to the fact that the laser beam it emits is at a relatively small angle, which is important for some applications, such as optical communications or sensors. Small-angle focusing VCSEL has higher beam quality and narrower divergence angle, making it more advantageous in certain applications.

[0014] 1. The utility model is convenient for cleaning VCSELs with small-angle focusing through the installed arc plate. When cleaning the surface of the spherical lens, after adjusting the angle of the arc plate through the connecting component, the No. 1 brush, the No. 2 brush and the No. 3 brush will all contact the surface of the spherical lens, and then the rotating ring will be rotated to rotate inside the annular groove, which will drive the strip plate to move.
