测量棱镜、反射片与三脚架

Survey Prisms, Reflectors & Tripods — Surveying & Geomatics Equipment

Prisms, targets, tripods and tribrachs decide whether a total station actually delivers its stated accuracy. We supply single circular prisms with holders, 360° prisms for robotic stations, retro-reflective target sheets for monitoring, heavy-duty aluminium tripods and tribrachs with optical plummet. Prism constant, centring accuracy, stability and thread compatibility decide the choice. Tripods are specified in ISO 12858-2 and tribrachs in ISO 12858-3, while prism constants are verified during EDM checks to ISO 17123-4.

How to specify

  1. Set the correct prism constant in the instrument; a 30 mm error is common.
  2. Check tribrach plummets regularly; a worn one causes centring errors.
  3. Use heavy wooden or aluminium tripods for long sights in wind.
