The imaging optics for this workstation version consist of the Raspberry Pi camera and the lens from the camera. To create a microscope, the lens is separated from the camera. This makes quite a good microscope objective with a field of view about 950μm across.
Take the lens spacer(fromstep){qty:1, cat:printedpart} and confirm that:
- It has been printed in black.
- It is dust free (You can blow air through to clean it)
- The central shaft is not obstructed by strings of plastic.
! Caution! The camera board is static sensitive. Before touching the Pi Camera, touch a metal-earthed object. If you own one, consider wearing an anti-static strap.
- Use nitrile gloves{Qty:2} to manipulate camera and lens.
- Take the Pi Camera{qty:1} out of the package. Make sure to hold it only by the sides of the board.
- Take the protective film off the lens.
- Take the Pi Camera lens tool{qty: 1} and place it over the lens
- Slowly unscrew the lens (About 4 full turns of the tool)
- Carefully lift off the lens.
- Save the lens and the camera.
- Place the Pi Camera lens on a clean surface with the side opposite the camera sensor on the bottom.
- Push the lens spacer down onto the lens until it clicks into place.
- Take the Pi Camera and place it on top of the pi camera platform(fromstep){qty:1, cat:printedpart}.
- Place the lens spacer over the camera.
- Use four M2x5mm cap head screws{qty:4} to secure the three parts together using a 1.5mm Ball-end Allen key{qty:1}
- Take an M3 nut{qty:1} and push it into the nut trap from the top
- Take an M3x10mm cap head screw{qty: 1} and screw it into the nut.
- Only screw it in a couple of turns. About 5 mm of thread should still be visible.
- Take the Pi Camera ribbon cable{qty:1}
- Pull the catch forward on the exposed Pi Camera connector
- Insert the ribbon cable with the contacts towards the board
- Close the catch on the connector
Set the [complete optics module]{output, qty:1} aside in a safe place.
