this is just a very small part of my project. I would consider it is a good-to-have feature. I know what I want but I just dont know where to get the right items.
Weight is quite important for my project so I hope the whole device can be very light. Do you know which stores sell this kind of device and I don't need to select the optics myself?
Thanks!
Hi all, I am new to lasers and optics in general.
I am currently working on a project and I need to focus a laser to a very small dot(around .1mm, smaller is better). the focal length should be around 100 mm(min) to 300mm (max).
I am willing to spend around 50 - 200 bucks.
Also, I wonder what...
