I have come across a project which used this Chinese laser module. Apparently from someone who worked with the mentioned laser, it emits IR light (noise) even though it's a green laser. While I was browsing for alternatives on Digikey, I have a hard time finding an alternative that has an IR filter built in to get rid of the noise. Here are my questions.
- From your experiences working with the laser modules ordered from Digikey, have you encountered any issues with IR noise?
- Should I be looking at lasers with similar wattage to ensure similar brightness?
Thanks in advance for your help!
