Dichroic Beamsplitters
and Coated Windows
TABLE OF CONTENTS

Dichroic Beamsplitters and Coated Windows:

U.S. Laser beamsplitters are generally used with our model N1001 beam delivery systems to reflect the laser wavelength, while allowing sufficient visible light to be transmitted for CCTV viewing. Beamsplitters are fabricated using u.v. grade fused silica substrates, which are polished to > 1/4 wave flatness. Substrates are then highly damage resistant multi-layer dielectrically coated for the appropriate reflectivity and wavelength. Unless otherwise specified, substrates are 2 1/8" diameter x 5/16" thick, and are coated for 45o incidence angle, and random polarization.  

When used to describe our beamsplitters, the following abbreviations and definitions apply:

  • Visible: 450-650 nm
  • HR: high reflectivity (>99.9 % reflectivity)
  • HT: high transmission (>~70 % transmission)
  • A/R: Anti-reflective (<.5 % reflection)
