Hi Folks!
We at the Walters are coming to the end of our supply of old-style incandescent bulbs that we have been using for near infrared photography with our multiband modified Z8 camera setup. I've found several vendors online from whom we could by the same or similar incandescent bulbs, but I am curious to know if anyone out there is using infrared LED sources for infrared photography. My understanding is that they tend to have rather spiky emission peaks, but perhaps there are arrays combining several that could be useful in the 700-1100 nm range?
If there is a workable infrared LED alternative, I would be interested in it from a sustainability perspective, as I imagine it would use less energy and last longer than old incandescents.
Would be very happy to hear from anyone with thoughts or experience with infrared LEDs.
Thanks!
