Testing my new laser power meter with another ‘rescue’ from a scrapped CD drive. Scavenging laser diodes leaves a lot of ‘debris’.. 🤷🏼‍♂️😂

It’s an infrared laser so I can’t see it (besides a minor glow of deep red), but my phone camera shows it as an eerie purple tone with the characteristic speckle-pattern.

The power meter? It has an absolutely massive thermopile sensor, no wonder it’s quite heavy 🙂 I don’t know much about it’s absolute accuracy, but I think it’ll be ok for my experimental (hobbyist) use.

The lasediode produces some 50mW power at 100mA current, which isn’t uncommon so be careful when playing with invisible light ☝🏻🚨
