Guidelines for Correct Results
General
TPS1200 instruments measure a distance using an invisible infrared laser beam
which emerges coaxial from the telescope objective. For application programs
without reflector a visible red laser beam is used which emerges in the same
manner. The visible red laser beam is available for reflectorless instruments.
)
Very short distances may be measured reflectorless with the infrared EDM to well
reflecting targets. Note that the distances are corrected with the additive constant
defined for the active reflector.
