Hi, this is my first post on the forum (I didn't see anywhere to introduce myself, although maybe I missed the thread, since this forum is gigantic).
I found this post while searching for a MWIR light source for my Agema Thermovision 470 MWIR camera, but I also have a cooled germanium-on-CMOS SWIR cam, the NoblePeak TriWave camera, which works from 350-1600nm or so (give or take if you push it a bit).
On the topic of the post, I recently got an Arcadia Deep Heat Projector bulb, which puts out copious amounts of light in NIR, SWIR, and MWIR (roughly 1000nm to 2500nm or so is the range, but I don't have an exact spectrum). The bulb is for keeping reptiles warm, but it works nicely for illumination in those bands.
Greetings to the community, and if there's a better place to make an intro, do tell me!
