Hi Yes exactly, I want to be able to project a collimated 10mm thick beam through a line generator lens with a fan angle of about 35 degree. So if I shine the laser on a wall 5m away I should see a 10mm thick line, about 3m wide. Thank you for the link olympus, I might buy that module to start...

Hey, I am trying to find a configuration for creating a thick (~10mm) laser line, fan angle around 35°. From what I understand the moulded plastic lenses or rod lenses need a narrow and focused beam to work. A powell lens is too heavy and bulky for me. Does anyone have any other ideas? I am...

Sorry maybe I was unclear The original configuration was: Collimating focus lens + line generating lens and now I switched to: Collimating focus lens + DOE 5 line lens However, instead of 5 parallel lines I generate maybe 50+ at very large angles

Hey, I have a PL520 520nm Osram module with a line generating lens (https://sites.google.com/site/dtrlpf/home/diodes/pl520-520nm-laser-diode) But instead of just one line I want to generate 5 parallel lines using this DOE: https://www.laserfuchs.de/de/doe-de-r252 So I just switched the lenses...

Another newbie question: Does diffraction lenses require a collimated focus lens or a converging focus lens? Basically I have a standard 12mm green laser module with a collimating focus lens and a line generator lens. I wanted to try replacing the line generator lense with a diffraction...
