Measuring method Pulse laser transmitter and image sensor with co-axial optics
Signal source (emittted beam) infrared laser diode (980 nm)
Class 1
(IEC60825-1 Ed. 2.0: 2007/FDA CDRH 21 CFR Part 1040.10 and
1040.11 (Complies with FDA performance standards for laser
products except for deviations pursuant to Laser Notice No.50, dated
June 24, 2007.))
Viewing angle ± 45’
Measuring range H: 360° (full transit)
V: Elevation angle 90° (when handle is attached: 70°) ,
Depression angle 41°

Auto Pointing measurement range
*11
360° Prism ATP1/ATP1S: 2 to 600 m (1,960 ft)
*3,14
Prism-5: 1.3 to 600 m (1,960 ft)
Prism- 2: 1.3 to 1,000 m (3,280 ft)
Reflective sheet RS10/30/50: 5 to 50 m (160 ft)
*12,*13
Reflective sheet RS90: 10 to 50 m (160 ft)

Time to completed Auto Pointing
*11
(When prism in field-of-view, at 100 m distance)/(using RS90N-K, at
50 m distance)
4 to 8 sec.
*15
Sighting accuracy (standard deviation)
*11
(fine measurement)
Prism: 1.2 mm or less (equivalent angle) (to 100 m),
(0.3 + 9ppm X D) or less (equivalent angle) (100 m and over)
Reflective sheet RS90N-K: 2 mm or less (equivalent angle)
*12,*13
*10 : Measurering time may be longer around elevation angle 90°, because the tilt compensation
is not in operation.
*11 : No haze, visibility over 20 km, slightly overcast (less than 30000 lx), no scintillation.
*12 : When using a reflective sheet for Auto Pointing, the size of sheet (10 to 90 mm) must be
selected to correspond to the distance being measured. Use smaller reflective sheets for
shorter distances.
*13 : Figures when the Auto Pointing beam strikes within 15° of the reflective sheet target.
*14 : Figures when the Auto Pointing beam strikes within elevation and depression angle 15° of the
360° prism.
*15 : Measurering time may be longer when search area is widely set and target is positioned far
from the sighting direction.
