| Abstract | ||
| 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 | ||
