Hi, i am using 919P-050-18HP and 918D-UV-OD3R detectors. Since there is a considerable difference in the power meter readings of these detectors (Ex: HP shows 79mW and OD3R shows 0.0138mW). I was wondering is there a factor that needs to be multiplied for the results in OD3R with Attn. ON state. I am using 2936R power meter. I am having issues while doing ZScan analysis, where is have to divide values from OD3R by 18HP.
