Tech Spec Polarizing Cube Beamsplitters
Apr 2006
Edmund Optics Inc.Request Info
BARRINGTON, N.J., April 26, 2006 -- Edmund Optics, a manufacturer of optical and imaging components, has introduced a precision-grade cube beamsplitter for high-power Nd:YAG lasers. Tech Spec high-energy polarizing cube beamsplitters use multilayer dielectric film technology to minimize reflection and absorption losses. The result is a beamsplitter that puts maximum optical power where it's needed while handling high laser-power densities up to 5 J/cm2, the company said.

EOBeamsplitters.jpgDesigned specifically for high-power laser applications at 532 nm or 1064 nm Yd:YAG lasers, these beamsplitters feature a precision fused silica substrate and high-energy coatings. A unique optical contact bonding method eliminates the need for adhesive between the prisms, simultaneously improving the damage threshold of the beamsplitter and parallelism of incoming and exiting beams. A V-coat antireflective coating at the design wavelength virtually eliminates energy loss, according to Edmund Optics.

The company said the beamsplitters are an excellent complement to Edmund's full suite of laser optics and accessories, and can be easily integrated into applications with its precision positioning equipment.

General specifications:
  • Designed for 532 nm or 1064 nm Nd:YAG lasers
  • Damage threshold tested for 5 J/cm2, 8 ns pulses
  • Extinction ratio > 500:1
