"Prism Pole" refers to a surveying pole equipped with a prism or other target for use with total stations or surveying instruments. 
 
If you meant to ask about a "Prism Pole" in general, here’s a description:
 
 Prism Pole (General Description):
 
A Prism Pole is a surveying accessory used to mount prisms or targets for precise measurements with total stations. Here are the key features and components typically associated with a Prism Pole:
 
1. Construction:
   - Material: Usually made of lightweight but durable materials like aluminum or fiberglass to withstand outdoor conditions.
   - Sections: Can be telescopic, allowing height adjustment for different surveying tasks.
   - Locking Mechanism: Equipped with clamps or twist locks to secure the extended sections at the desired height.
 
2. Prism Mount:
   - Top Adapter: Includes a mount or adapter at the top to securely attach prisms or other targets.
   - Threaded Mount: Often features a standard 5/8" x 11 threaded mount to screw onto the base of the prism.
 
3. Height Markings:
   - Graduations: Markings along the length of the pole to indicate height, essential for precise elevation measurements during surveys.
 
4. Base and Foot:
   - Pointed Foot: The bottom of the pole typically ends in a pointed foot or spike to anchor the pole securely in the ground.
   - Level Vial: Some models may include a built-in level vial to ensure the pole is plumb (vertically aligned) during measurements.
 
5. Compatibility:
   - Total Stations: Designed to be compatible with various total stations and surveying instruments that use prisms for distance measurements.
 
6. Portability:
   - Collapsed Length: Telescopic poles can collapse to a shorter length for easier transport and storage.
 
 Usage:
 
- Setup: Extend the prism pole to the desired height and secure it using the locking mechanism.
- Mounting: Attach a prism or target securely to the top adapter of the pole.
- Surveying: Use the total station to send signals towards the mounted prism for distance measurements, ensuring the prism pole remains stable and plumb for accurate results.
 
 Applications:
 
- Construction Layout: Used for precise layout work, setting out points, and measuring distances during construction projects.
- Topographic Surveys: Essential for elevation measurements and establishing accurate benchmarks in topographic surveys.
- Monitoring: Used in deformation monitoring of structures over time by precisely measuring movements relative to fixed points.
 
 Conclusion:
 
A Prism Pole is an indispensable tool in surveying, facilitating accurate distance measurements and height determinations with total stations. Its design features ensure stability, precision, and compatibility with surveying equipment, making it essential for various surveying applications in both construction and engineering projects.
