Optical Glass Ball Lenses and Half ball lenses
Ball lenses are commonly used for laser collimating and focusing, laser-to-fiber coupling, fiber-to-fiber coupling, and fiber-to-detector coupling. It is used in such devices as endoscopes, microscope objectives or fiber optics couplers.

Also, what
are machine vision lenses? That is, the lens captures the image and
transmits it to the image sensor in the camera. Lenses vary in optical
quality and price, and the lens used determines the quality and
resolution of the images captured. Most vision system cameras offer two
main types of lenses: interchangeable lenses and fixed lenses.
The micro
ball lens is used to improve the signal coupling between the
transmitter, fiber optics, transmitter, receiver and detector, depending
on the application. They can achieve a very high level of surface
finish. In terms of visual appearance, our micro ball lenses can have a
scratch/hole-free surface finish (depending on the diameter of the micro ball lens) at multiple magnifications.
