Laser Scanning Microscope from Blu-ray Player #3: Increasing the Resolution

This is part 3 of my series on building a laser scanning microscope from an optical pickup unit I salvaged from a defective Blu-ray player. This version fixes some issues I had with the prototype shown in part 2. In this project, I used 3D prints from PCBWay.
