The instrument contains visible and invisible laser sources:
• A laser diode for distance measuring in DR mode and laser pointer function operating at 660
nm (visible light), with a beam divergence of 0.4 x 0.4 mrad and an output power of <5 mW,
while the emission is coaxial with the telescope. This mode operates in LASER CLASS 3R.
• The laser diode for distance measuring in prism mode operates at 660 nm (visible light), with
a beam divergence of 0.4 x 0.4 mrad and an output power of <0.017 mW, while the emission is
coaxial with the telescope. This mode operates in LASER CLASS 1.
• An Autolock laser diode operates at 785 nm (infrared, non-visible light), with a beam
divergence of 38.5 mrad and an output power of < 0.35 mW, while the emission is coaxial with
the telescope. This mode operates in LASER CLASS 1.
