Measurement of layer-by-layer self-assembly film using RAS-8000 grazing angle specular reflectance accessory

Introduction

Decent spectra cannot be obtained if thin films such as organic LB films are measured using a reflector with a small angle of incidence. This type of measurement however becomes possible if a grazing angle specular reflectance accessory is used. Introduced here is an example of thin film measurement using layer-by-layer self-assembly film to illustrate the effect of different incident angles on the spectrum.
