C-Mount, 10mm Length Tube (F)

Example here. (Stock No. #54-629)

C-Mount, Adjustable Length Tube (G)

Example here. (Stock No. #58-756)

3-D printed Optical Assembly Clamp

Example here.

3-D printed Raspberry Pi Camera Module mount

Example here.

Instructions

1. Screw Objective Lens (A) into DIN/C-Mount Adapter (B) so that the outer screw thread faces away from the lens.

2. Attach Adapter to female connector of C-Mount 40mm Tube (C).

3. Remove the retaining ring from the Lens Mount (D) - this may require a flat-head screwdriver to unscrew it from inside.

4. Place the Biconvex Lens (E) into the Lens Mount (D), being careful not to scratch it.

5. Reattach the retaining ring to the Lens Mount, ensuring it keeps the lens firmly in place.

6. Now attach the female connector of the Lens Mount (D) to the Objective and 40mm Tube assembly (A-C).

7. Attach the 10mm Tube (F) followed by the Adjustable Length Tube (G).

8. The Optical Assembly can now be attached to the microscope structure using the 3-D printed clamp.

9. The Raspberry Pi Camera Module (with lens removed) can be attached using the 3-D printed connector.

10. The Adjustable Length Tube can be adjusted until a focussed image is formed when the object is an appropriate distance from the objective.
