Default [UVIR] tried out the wideband dual profile filter

purchased the XDP (dual profile) filter from MAXMAX.. here is a result.. preset WB shot from subject.

Nikon D200 UV-VIS-IR, XDP filter ,Nikkor 20mm f/3.5 Ai-S, 1/25s f/8.0 at 20.0mm iso200



and it has a window in the UV... here is the filter with the Baader U-filter

Nikon EL-Nikkor 150mm f/5.6A, 1/25s f/11 iso320, Baader+XDP



good thing i saved that sunflower.. it has about had it though.

any thoughts on what this filter is?

too funny!...

yeah... MAXMAX won't provide the transmission spectra or tell me what it is... but it passes UV and IR as well as some visible.... kinda like the Schott UG-5 1mm thick glass.. http://www.optical-filters.com/ug5.html but this glass is 2.5+ mm thick...
