Ultra Broadband > Dielectric Plate Beamsplitters BK7

Introduction

Ultra Broadband Dielectric Beamsplitters are all dielectric multilayer beamsplitter coatings manufactured with alternating high and low index coating layers. These mirrors can be used over a broad wavelength range. Available to split beam R:T=50%:50%,the rear surface is coated with anti reflection coating minimizing back reflections and second surface reflections.
