Thank you so much for your reply.
I have a query about the setting up of FWHM.
you have mentioned that width must be larger than the source wavelength.
As we have used 532 nm laser for our experiment, what should be the value of FWHM and time delay?
one more question..As i am interested for calculation of transmittance spectra and reflection spectra, which parameters i should care for?
As you mentioned the design described in No. 1 is correct for my study, i am also curious to know about the design provided in no.2. Is it wrong?
Hope you will get my point.
