LDT50
Theodolite

Highlights

• Laser beam reaches over 400 meters in cloudy daylight conditions and even further dark environments such as tunnels or underground sites
• Switchable between focused and parallel beams
• The telescope unit is fully transiting
• The laser beam spot is extremely close to a perfect circle, making the spot center easy to determine for quick and accurate results.

  The LDT50 integrates breakthrough technology with a highly reliable digital theodolite. Standing in harsh operating conditions, its dependable laser dramatically enhances your job efficiency by providing a bright sharp beam.

Dual-axis compensator

The DT210/DT510 automatically compensate both Vertical and Horizontal angles by monitoring the tilt of the instrument in X&Y two directions

Long-life laser diode

By employing a laser diode instead of an H-Ne laser tube, the telescope has been made compact and fully transmitting.

Sharp beam - round spot

Breakthrough technology has achieved a laser beam spot extremely close to a perfect circle.

One-touch switching focused beam / parallel beam

Focused beam - beam spot becomes smallest at the focused position. Parallel beam- as the diameter remains constant over any distance, the parallel beam is convenient for direction control during excavation. With the LDT50, a parallel beam can be emitted without the need of accessories by simply adjusting the focusing ring to the parallel beam mark, resulting in a bright circular beam reaching up to 200 meters (656 feet).

Laser range over 400 meters

The laser output power can be set to either 1.W or 2.5mW as required. The instrument employs a safe Class 3A laser so there is no need for special safety precautions during use. Angle Measurement Accuracy (DIN18723) 5" Display Resolution 1" / 5" (0.2 mgon / 1 mgon), selectable Laser Range Output power 1mW Over 656 ft. (200m) Output power 2.5mW Over 1,312 ft.
