808- 850 nm

[Edbux]

Need advice on how to get close to a round dot instead of a rectangle. I would also like to build my own module with an 808, 830, 850 diode. What board should I get and housing. No host needed. Power < 100mw

Which diode? It's going to be pretty round already if you're using a low power single mode diode.
