Measurements methods
M-line spectroscopy (Metricon Prism Coupler)
The Metricon Model Prism Coupler utilizes advanced optical waveguiding techniques to rapidly and accurately measure both the thickness and the refractive index/birefringence of dielectric and polymer films as well as refractive index of bulk materials at five wavelenghts (473, 633, 964, 1311 or 1552 nm). The method offers unique advantages over conventional refractometers and instruments based on ellipsometry or spectrophotometry.
