Thread: IR Torch options

What's out there in the 800-850nm range that has a really good output?

I'm finding my nightvision's onboard IR light is struggling to illuminate out far enough, however if I use a red filtered spotlight (EG visible red light) then I can see as far as I want, which tells me it's an illuminator issue rather than the limits of the optics.

I've tried 950nm illuminators but the scope is already struggling to get enough light, so I don't think that's a good solution.

I'd prefer to go with a true IR illuminator rather than keep putting red filters on regular lights.

I've been doing some digging and on the UK forums quite a few people recommend vcsel chip driven IR illuminators (basically a laser diode rather than plain LED), but they don't seem to be common in NZ, or I'm looking in the wrong places.

Any suggestions?
