Wink Unable to focus

Hi all, I am a newbie to laser field. Currently I am doing a laser based engraving project for my university course where I have to use the laser to engrave words on woods.

I have did some research and bought a LPC-826 laser diode alongside with a module for 5.6mm diameter.

After installing the laser diode into the module and tested with a laser driver circuit I build on my own and began the testing it seems that the laser beam produced is not focused AT ALL.



I am wondering whether did I broke my laser diode or the lens is not good. I learnt to install the diode through some of the youtube video so I don't think it's the installation process error. Any guidance will be appreciated.

Thanks in advance.

Default Re: Unable to focus

To me it seems like you lens or your diode window is dirty.

Try checking if those are clean. The smallest dusts and dirt can have a very big effect.

If they are both clean your diode may be gone. But first things first
