Distance measurement (RL: reflectorless)
•
Type visible red laser
• Carrier wavelength 0.670 µm
• Measuring system special frequency system
basis 100 MHz 1.5 m
• EDM type coaxial
• Display (least count) 1 mm
• Laser spot size: approx. 7 x 14 mm / 20 m
ca. 10 x 20 mm / 50 m
• Range of measurement: 1.5 m to 80 m
(to target plate art.no. 710333)
• Prism constant: + 34.4 mm
Beam interruptions, severe heat shimmer
and moving objects within the beam path
can result in deviations from the specified
accuracy.
