K9 wedge beam splitter

  • The wedge angle of the wedge-shaped beam splitter and the antireflection film on the back can reduce the ghost image interference reflected on the back surface. Ensure high precision of transmitted light and reflected light.
  • Borisuns optics supports the customization of wedge-shaped beam splitter with various beam splitting ratios, and the antireflection film includes UV, vis and NIR.
