Ultra Broadband Dielectric Mirrors > Dielectric Mirror BK7

Introduction

Ultra Broadband Dielectric Mirrors are manufactured using all dielectric multi-layer coatings of alternating high and low index layers. These are specifically designed for use at 45 degrees angle of incidence. The mirrors are designed to achieve broad reflection like never before. Visible near infrared and other multiple wavelengths are covered with single mirror.
