  • Made from BK7
  • Cemented for low power applications
  • Typical damage threshold: >0.1 J/cm2, 10 Hz at 1064 nm
  • Broadband anti-reflection coated: R<1% @ 450-700 nm or R<1% @ 750-1100 nm

 

Non-polarizing cube beamsplitters are made of two right angle prisms cemented together with a partially reflecting surface on the internal (protected) face. Four sides of the beamsplitter cubes are broadband anti-reflection coated. The coatings are designed for 450-700 nm or 750-1100 nm range.

 

Cubes provide 50:50 split ratio and come in four different sizes. Cubes can be supplied unmounted or mounted, mounted cubes have codes with M2Ps or M2P suffixes.
