Integraf PFG-03C exposure time?

Post by tonyr »

What is the best exposure to use for PFG-03C plates at 532nm? The website says 3µJ/cm² for "exposure peak sensitivity", it looks like 4mJ/cm² in the first plot below, and in the second plot it looks like -2 log(cm²/µJ) = 0.01 cm²/µJ = 100 µJ/cm²?

Am I interpreting these right? Got any advice based on actual experience?

Found some better info on the Slavich website https://www.slavich.com/holo_ufg-panchromatic. They quote 3mJ/cm² for green and red and 2mJ/cm² for blue. Here are the correct plots.

Found some other useful info while researching this. Here is an optical density plot from this paper https://doi.org/10.1364/AO.40.000622.

This paper http://publicaciones.eafit.edu.co/index ... 75/html_13 has the relative ratios for each color.
