Broadband beam splitter

  • The front surface of the beamsplitter plate is coated with beamsplitter coating, and the rear surface is usually coated with antireflective film to reduce the interference effect between beams and ghost images. The spectroscopic flat film is light in weight, moderate in price and relatively easy to make.
  • Borisun optics supports customization of a variety of beamsplitter coatings, including broadband beamsplitter coatings, aluminized dot matrix beamsplitter coatings, elliptical beamsplitter coatings and visible beamsplitter coatings.
