I remember having used a quartz exposed to the coating vapour in vacuum chamber , which frequency was directly linked to the coating thickness. This allowed us to precisely monitor the coating thickness and get interference filters at the needed wavelength. The same can be used for preparing antireflective coatings in vacuum chambers.
If you intend to measure the transmittance of an existing coating on a panel top glass cover , a transmission spectrometer is adequate to get the transmission spectrum. You may as well use two calibrated solar cells, one behind and the other in front of the glass cover, and measure the ratio of their output current.
Optical technique could be useful.

Hi Abhilasha
I think you can easily determine the coating thickness using SEM for the cross section of your sample.
It is accurate and you may sea not only thickness but also the quality of your coating; adhesion, compacting, ....
