measuring IR

[tacomanmcjab]

Hi Guy this is my first post here :wave:

What is a cheap and easy way to somewhat reliably measure IR?

The easiest way to DETECT IR is with a camera, most cheep webcams and X10 cams can see IR (to find out if yours can, turn it on and point your TV remote at it) You can then see the IR in a laser fanning out from the beam, though this is horribly INNCURATE it will let you see to some extent the ammount of IR. Really you need a spectrometer (?) to meaure it.

The only two practical ways to nondestructively measure IR that I'm aware of are:

1: Use 532nm blocking glasses or goggles and use a laser power meter to measure the remaining power (if any).

2: If you have access to a spectrometer (most people do not, but some do), use the instrument to check both the 532nm and 808nm laser lines.
If the 808nm laser line does not show at all, you're probably alright from an IR standpoint.
