The LBTEK Near-Infrared Laser Alignment Disk IRDC3 features a circular infrared-visible coating with a diameter of Ø13 mm, used for determining the position of the near-infrared beam. The Ø1.5 mm center through hole is used to align the beam. After aligning the beam, the alignment disk can be removed without interfering with the optical path, and it can be placed back into approximately the same position later. The IRDC3 laser alignment disk is compatible with LBTEK's Ø25.4 mm fixed lens holders or Ø25.4 mm lens tubes.
