Re: Using a 660nm laser to expose legacy AgX Agfa, Ilford, HRT (BB) plates
Hi Jody Have you tried exposing the old red sensitive plates to green laser light? Obviously they don't have the correct dyes to be sensitive to green but given modern green lasers are fairly powerful I wonder if the emulsion would respond anyway? And a similar thought.... Were you ever to experimen...

Re: Spectrometer
Hi Joe It was a while ago now... but there was an open source project, by a group called "myspectral" https://labrigger.com/blog/2012/06/25/introducing-the-spectrino/ I just purchased the linear CCD and did the software myself. It was a struggle to prevent the CCD from saturating. I also r...

Re: Spectrometer
Hi Joe Thanks for reporting on this. I am trying to build the same thing but from component parts... similar to what you mentioned: a linear (one dimensional) CCD and a reflection grating software I wrote myself... but I am not sure if I could resolve the fine splitting of modes from the diode I was...
