I would like to make an infrared flashlight for sony camcorder night shot?
Would it be as easy as an infrared filter and place it on a flashlight? You need a certain type of bulb? How can this be done? Would you use it to improve making the night on my camcorder Sony HDR-SR11. Thank you for any information. I think using a flashlight to 830nm. Is this ideal? Thank you for any information.
You can get specialist IR lights for recording bats – these have a peak output of 810nm, so 830nm should be OK. I don’t know that it’s “ideal” though – the “bat lights” are a compromise so as not to disturb the bats, and the cut-off for the IR detector is around 1000nm. I don’t know where the peak sensitivity is, though.
I’d have thought that IR emitting LEDs would be a better option than using a filter.
