👉Total Station

✅ Mainframe: The central body of the instrument housing optics, electronics, and controls. It’s the core unit that performs angle and distance measurements.
✅ Tripod: Provides stable support for the total station, ensuring accurate readings by minimizing vibrations or movement.
✅ Prism (on Prism Pole): Reflects the instrument’s laser/infrared beam back to the total station, enabling precise distance measurement.
✅ Prism Pole Tripod: Holds the prism pole upright for stable alignment during surveying.
✅ Vertical Clamp: Locks the telescope in the vertical plane, allowing fixed angle measurements.
✅ Horizontal Tangent Screw: Fine adjustment screw for precise horizontal angle alignment. Appears twice for different control points.
✅ Foot Screw: Used to level the instrument by adjusting the base plate.
✅ Mirror: Assists in sighting and alignment, often part of the optical system.
✅ Horizontal Circle Clamp: Locks the instrument’s horizontal circle, stabilizing angle measurements.

📌 Importance
The total station combines electronic distance measurement (EDM) and angle measurement, making it indispensable for civil engineering, construction layout, and land surveying.

It ensures accuracy in plotting points, measuring elevations, and setting out designs.
