Product Details

Product Model: 61-6949-39
Product Brand: SIGMAKOKI CO., LTD.

Features

  • Zoom-type laser beam expander for high power variable up to 1~3 times.
  • The diopter correction function allows fine adjustment of collimation.
  • It can be ***d for high-precision optical systems such as interferometers and laser machining by lens design that takes wavefront aberration into consideration.
  • The optical system of the beam expander has an air gap configuration without gluing lenses together. This allows it to be ***d with high-power lasers.
  • The Galileo lens configuration reduces the number of aberration correction lenses and shortens the total length of the beam expander.
  • By turning the diopter ring in the center of the beam expander, you can change the beam from foc***d to collimated to divergent.
  • Use this when you need a strict collimating adjustment or when you want to change the position of the beam waist.
  • Laser beam expander holder (BE-M22 H, BE-M34 H) with fine aori adjustment to fix the beam expander is available.
  • * The beam expander cannot be ***d in the opposite direction to produce collimated light with reduced beam diameter.
  • * Determine the divergence angle of the laser beam and the position of the beam waist, and *** an appropriate optical system.
