Filter measurements data base

Post by christian viladrich » Sun Jul 19, 2020 4:39 pm

Hi,
I don't know whether this is the right place to post this ... We (Fred Jabet, Alexander Lhoest and myself) have measured a number of filters with a spectrometer from 300 to 1050 nm:

This is not specific to solar astronomy, but it can be occasionaly helpfull for various uses.
We also have a number of LPR filters measured. I'll try to post these later on.

Christian,
Good resource.
I'm a little surprised with the Baader D CCD result.
I use this as an ERF for the CaK filter set up, and thought the transmission at 393nm was higher.
