Femtoline Broadband Laser Beamsplitters

  • Coated @ 720-880 nm or 750-850 nm
  • Designed for S or P polarization
  • Laser damage threshold: >50 mJ/cm2, 50 fsec pulse, 800 nm typical

The beamsplitter splits average polarized laser beam into two beams separated by 90° from each other.

The standard substrate thickness is 3 mm. If you need thinner substrate, please choose from Precision Thin Round Windows.
