Thanks for your reply.
I didn't change my thoughts, my initial target was maximize transmission at one wavelength and minimize at others because simply the device will work along a wavelength range.
When you say ''you can first get the average transmission at all other wavelength except that specific wavelength, say T_ave; then you have the transmission at the specific wavelength T_singe. you can define your FOM as
FOM=T_singe/T_ave''
do you mean by writing a script in ''Figure of merit script''? I tried to add any conditions but I couldn't. I believe that the only way to specify any conditions is by using a script, is it right?
