Where can I get this laser modules?

[open94]

I am planning a DIY similar to the link.
http://www.csksoft.net/blog/post/lowcost.laserkbd_part1.html (recommend Google translation)

Links use laser modules that project keyboard patterns. Where can I buy this?
Can I customize pattern? (Can I change the image of the lens and order it?)


I used a lot of time because I didn't know the exact search word, but I didn't get any results.

Thank you for your help.

Thank you so much for your kind reply.

However, rather than technical problems, Link said they purchased hologram equipment directly from the Internet used to create keyboard screens. I searched for similar keywords to find these modules, but I couldn't find them. Where can I find it?

Can you tell me the exact search word?
