  • Page 29: Chapter 7 Alignment

    7.1. Laser Source Alignment Verify the gross alignment of the laser source through the MPH16-UC emission port. Place an iris between the laser source and the MPH16-UC input to align the laser with the optical axis of the pinhole wheel.

  • Page 30: Mph16-Uc Fine Manual Alignment

    Switch off the laser source and remove the translucent material (tape) from the emission port. 7.2. MPH16-UC Fine Manual Alignment WARNING DO NOT adjust the pinhole size using software before performing the laser alignment. This may damage the motorized pinhole through exposition to focused laser beam.
  • Page 31 Motorized Pinhole Wheel, Uncoated Chapter 7: Alignment Beams That Require Adjusted Beam Adjustments To achieve a round beam of maximum intensity, adjust both lens and pinhole wheel. Pinhole Wheel Alignment: use the +/- button in the MPH16 Pinhole Control window to rotate the pinhole wheel in both directions until you achieve a maximum beam brightness on the white cardboard / white printer paper.

  • Page 32: Lens Alignment

    Repeat Step 3 until you align the smallest pinhole size (25 μm). Note: For optimal alignment, use a power meter (not included with the MPH16-UC unit) to measure the transmitted beam intensity. Adjust the pinhole wheel and lens alignment for maximum reading on the power meter.
