Evaluation of Transmittance/Reflectance Spectra of Dielectric Multilayer Films - Utilizing a Variable Angle Measurement Unit -

Introduction

Dielectric multilayer films are coated on various optical elements such as lenses, mirrors and filters. They are also applied to items familiar to us such as cameras and binoculars. In addition, they are often utilized in photometers and are a very important optical element. Here, we describe using a UV-VIS spectrophotometer with a variable angle measurement unit to measure the transmittance and reflectance spectra of filters coated with dielectric multilayer films.
