Broadband Cavity Enhanced Absorption Spectroscopy (BBCEAS) is
employed in this study as a sensitive technique for measuring the
absorption of thin films deposited onto a glass substrate. A thin film of the
analytic Rhodamine B was deposited on glass microscope coverslips. Drop
coating method was used to deposit a thin film over the microscope
coverslips. The most sensitive measurements as determined by the
minimum detectable loss per pass (?Fmin(t)) at 397 nm and the R ? 0.99
ultra violet mirror set. A value of ?Fmin(t) = 5.2×10-6 was obtained.
