7.1. Laser Source Alignment Verify the gross alignment of the laser source through the MPH16-B emission port. Place an iris between the laser source and the MPH16-B input to align the laser with the optical axis of the pinhole wheel.
Switch off the laser source and remove the translucent material (tape) from the emission port. 7.2. MPH16-B 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.

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