Universal Beam Splitters

The most useful device in any laser lab; the Universal Beam Splitter*. Variable transmission from 10% to 98%. Variable reflectivity from 90% to 2%.


  • Constant 90 degree reflection     
  • Material: Fused Silica     
  • Clear aperture: 5mm    
  • Transmitted beam offset < 0.010mm     
  • Fits standard 1" diameter mirror mounts     
  • Nonpolarizing (S-P<2%)     
  • Adhesive Free    
  • Loss = 1%    


 * Not completely Universal, the light must be monochromatic and if the laser is pulsed then pulses cannot be shorter than 100 pico seconds in length.
