Description

This light microscope (Olympus BX51M) can be used to observe patterns and samples optically via 5x, 10x, 50x and 100x objective lenses. It also is equipped with a spectroscopic reflectometer (Filmetrics model F40) that can measure the thickness of transparent and translucent thin films. Spectroscopic reflectometry works by comparing the spectral amplitude and periodicity of light that is reflected at normal incidence from a thin film against the light that is reflected from a known reference sample; the results are fit to a mathematical model that takes into account estimated values for n (refractive index), k (absorption coefficient), and thickness.

Applications
