Hey all,
When it comes to arc lamps, it looks like the safety concern everybody talks about is in regards to UV exposure. This, however, seems to be more suited for Hg sources instead for Xe sources. My question is in regards to whether there should be any concerns with the IR portion of the spectrum. Xe arc lamps have several high intensity peaks in the NIR, so I was wondering if this is of any / should be of more concern in regards to lab safety? My understanding is that NIR light is just as well focused by the human eye as visible light (even though you can't see it) thus making my question even more prevalent.
Just a quick background: I'm coming up with a setup that includes a Xe arc lamp. The arc itself isn't exposed, but the light will be propagated through free space. Of course, there is also the light that leaks out of the enclosure containing the bulb.
If anyone has some experience with this or other useful thoughts, I'd love to hear them!
For quick reference:
