Guest Posted January 5, 2020 Share Posted January 5, 2020 Now that is cool! Is this just the 980bp10 filter, or is it stacked with a longer wavelength cutoff as well? Link to comment
Andy Perrin Posted January 5, 2020 Author Share Posted January 5, 2020 980bp10 is a dichroic bandpass, so it does not need a longer wavelength cutoff filter - it passes from 970-990nm only. It's a Thorlabs filter, so it is blocked to OD4+. Link to comment
Stefano Posted January 5, 2020 Share Posted January 5, 2020 Maybe you can try with a 980 nm LED, or with a 976 nm laser diode (it almost seems like that they were made for this, they have the exact wavelength of the water absorption). Link to comment
Andrea B. Posted January 6, 2020 Share Posted January 6, 2020 Creepamondo! And I absolutely love both photos as photographs. The first one has excellent composition. Lines, squares, diagonals.And the 2nd one has excellent "story-telling". {{{ Or would that be excellent methaphorical qualities? }}} Link to comment
Andy Perrin Posted January 6, 2020 Author Share Posted January 6, 2020 Thanks so much, Andrea! Yes, the first one is my favorite of the two. I moved the light to a particular location near the floor and I went, "WHOA, HOLD IT RIGHT THERE!" Link to comment

Andy Perrin Posted January 6, 2020 Author Share Posted January 6, 2020 It is a one inch filter, yes. I have a 28-52mm step ring and the 1” filter is in a 28mm ring that screws into it. Link to comment
