Frequently Asked Questions

How does a prism pole work?

A prism pole features a bracket that attaches prisms and other targets to the top of the pole for distance measurement. Because of this pole’s graduations and alternating red and white bands, it can also be used with optical levels for measuring elevations and grades.

How do I plumb a prism pole?

Most surveying prism poles come with level vials. Before using a level vial, you have to ensure that it is calibrated. After checking its calibration, try to plumb your pole until the bubbles are at the center.

How do I calibrate a prism pole’s vial?

  1. Find a doorframe with a top jamb and a sill into which you can drill holes.
  2. Drill a small hole into the top jamb of the doorframe.
  3. Use a plumb bob to find a point in the door sill directly below the hole in the top jamb.
  4. Place the prism pole’s tip in the sill’s hole.
  5. Extend the prism pole until its top fits into the top jamb’s hole, and lock the pole’s height in place.
  6. Turn the vial’s adjustment screws until its bubble is centered.
  7. Rotate the pole to check if the bubble remains at the center.

How do I adjust a prism pole?

After mounting the prism on the pole, release the pole’s lock mechanism and extend it to your preferred prism height. Then, lock the pole’s height in place. Finally, make sure that it is plumb by checking the level vial.

Can a retroreflector be placed on a prism pole?

Yes. In fact, prism poles have brackets that are designed for mounting retroreflectors or corner cubes.

Prism Poles

Setting the boundaries of areas calls for the task of surveying, and this task needs the use of surveying instruments. One of these instruments is a prism, which can reflect light back towards the source, such as total stations. Prisms are usually mounted on poles for added visibility, but these poles also offer many other functions. Because of their graduations and bright, alternating colors, they can be used with optical levels and help in measuring distances, elevations, and grades. Prism poles that can be ordered here on Engineer Warehouse are constructed with different kinds of durable materials. Some are made of carbon fiber, which provides these poles with pure black color and strength without adding weight. Some poles are constructed with aluminum, which is also durable and lightweight, while others have a fiberglass construction. Compared to aluminum, fiberglass prism poles are heavier but they are more durable and temperature-resistant, making them suitable in settings with inconsistent and extreme temperatures. For a comfortable and firm hold, some offer soft, ergonomic grips. For portability, most of these poles are conveniently lightweight, and there are also prism poles of the telescopic type and those that can be disassembled.
