Seeing invisible light (infrared light)
This filter transmit only infrared.
I haven’t found any datasheets.
where to buy
Infrared Filter x 1 / Fimeko Oy, Helsinki
Note
Remember infrared is invisible for your eyes so even if you look at the world through the filter, it shows only “Black”. You have to see it through a camera. Some cameras has the safety filter which cuts the infrared. In this case, your infrared filter won’t work. I found iSight and Nokia 6330 camera work well at least!
You need to chose one filter from several types of the infrared filters. It depends on which nano meter of infrared you want to transmit. Infrared LED generally emit 940nm light so the filter which transmits 940nm at maximum could be the most useful infrared filter.
