4. Setup
4.1. Assembling the Camera and Adapters
- Identify the 0.5X C-mount adapter. This adapter can be separated into two parts: an 'A tube' for 23.2mm mounting and a 'B tube' for C-mount size.
- If using a C-mount microscope, twist the 'B tube' directly into the microscope's C-mount port.
- If using a 23.2mm eyepiece port, twist the 'A tube' into the 'B tube' first, then insert the assembled adapter into the 23.2mm eyepiece port.
- For 30mm or 30.5mm eyepiece ports, use the corresponding adapter rings provided. Insert the 0.5X C-mount adapter (with or without the 'A tube' depending on the microscope type) into the appropriate adapter ring, then insert into the microscope.
