Telescope parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.
#PartQtyWhat it does
1 Objective Lens 1× Coated achromatic objective, around 32–40 mm aperture, that forms the image of the staff.
2 Internal Focusing Lens 1× Negative lens sliding inside the telescope tube to focus from about 0.3 m to infinity while the tube stays sealed.
3 Focus Knob 1× Side-mounted knob driving the focusing slide through a rack and pinion.
4 Helical Gear Pair 1× Focusing rack and pinion
5 Reticle Plate 1× Glass plate etched with the horizontal crosshair plus upper and lower stadia lines for optical distance measurement at a 1:100 ratio.
6 Eyepiece Group 1× Focusable ocular giving around 30× magnification and a dioptre ring for the reticle.
7 Peep Sight 1× Notch-and-bead sight on top of the telescope for coarse aiming at the staff before fine pointing.
