P.S In this application, smallness is critical, the entire laser device needs to be less than one inch or preferably smaller. Low cost of course is always important.
Hi
I am new and have a question that perhaps some laser guru can help out with.
I need a very small and minimally divergent beam, preferably IR, transmitted via a single fiber, to remain virtually non divergent from 0 to 6 inches from the end of the fiber.
I am working in a very small space...
