  • Fine alignment with kinematic opto-mechanical mounts to achieve collimation of a free-beam laser, utilizing polarization optics, spatial filters, and reflectors (plano and parabolic).
  • Format correct geometry with precise angles to produce the desired VPH. Typically producing specific line spacing for gratings.
  • Trained in processing of exposed (written grating) in chemistry (fixer, water and isopropyl alcohol).
  • Verifying grating efficiency and performance through use of spectrometers and other equipment.
  • Tune, cure, and seal grating in preparation for product use.
  • Performing any cutting, scribing, or grinding operations as needed.
  • Perform final QC using the developed procedure.
