Links to sites and softwarePosted by Daddy-o Sep 10, 2013 07:50AM
Here is a link to a site that lists transmission curves of many color filters - e.g. Wratten filters.
It looks like Schott RG665 is most like VE2, and might be the long-pass filter we need on a modified SIgma SD100 camera. We need it with 58mm thread, though.
Wratten #25A is available from B&H with 58mm thread but has its cutoff at 620 nm.
B&H have a 58mm Polaroid that looks ok. Transmits from 720 nm and up.
