Beam Splitters

Overview

Polarization, Energy or Wavelength

Beamsplitters are used to split light by polarization, energy, or wavelength. Foreal offers both plate and cube beamsplitters.

Polarization Based Beamsplitters:

  • Tp:Ts > 200:1

  • Tp:Ts > 500:1

  • Tp:Ts > 1,000:1

  • Tp:Ts > 10,00:1

Energy Based Beamsplitters:

  • T/R = 20/80

  • T/R = 30/70

  • T/R = 40/60

  • T/R = 50/50

  • Tolerance: +/-1%

Wavelength Based Beamsplitters

  • Tavg > 90%

  • Ravg > 99%

  • AOI: 45deg
