Spectra Precision FOCUS 35 Robotic Total Station

The Spectra Precision FOCUS 35 is a motorized total stations providing high speed, accuracy and precision in measurement.

The FOCUS 35 robotic instrument moves the power of the observer from the instrument to the range pole, improving efficiency. The speed of observation and precise positioning of the FOCUS 35 Robotic Total Station is provided by patented StepDrive motion technology, which controls the horizontal and vertical motion of the motors, eliminating the need for traditional motion locks.

The FOCUS 35 includes a tracking sensor that uses LockNGo FastTrack tracking technology, enabling the instrument to constantly lock onto the prism. The FOCUS 35 RX extended operation models feature market-leading battery life.

The FOCUS 35 is available in 1”, 2”, 3” or 5” accuracies and is controlled by the Spectra Precision Survey Pro™ field software using an onboard Windows CE touchscreen interface. The FOCUS 35 is also designed to be controlled externally by Spectra Precision Ranger™, Nomad™ or T41® data collectors running Spectra Precision Survey Pro field software, Spectra Precision Layout Pro or Spectra Precision FAST Survey on the Ranger or Nomad.

The speed of observation and precise positioning of the FOCUS 35 robotic total station is provided by patented StepDrive ™ technology. StepDrive controls the horizontal and vertical motion of the motors, so there is no need for traditional motion locks. Using the motorized drives it is possible to precisely turn to, and repeat angle measurements. This results in quick and reliable measurements which substantially increases your staking productivity. The Robotic, RX and LockNGo™ FOCUS 35 models include a tracking sensor that uses LockNGo technology enabling the instrument to constantly lock onto the prism. The benefit of LockNGo technology is the ability to follow the prism at all times and reduces downtime from not having to re-point the instrument on every observation.

To maintain contact between the FOCUS 35 instrument and the remote observer with the range pole and prism, the robotic solution must include a communication link. The FOCUS 35 uses an integrated 2.4 GHz radio modem as does the Spectra Precision Ranger™ 3 data collector. The 2.4 GHz radio modems provide interference free robotic data communications.

Once your robotic communications have been established you can control all the functions of the FOCUS 35 from the range pole as you move through the job site making measurements. This makes it possible for a single surveyor to perform high accuracy stakeout, layout or topographic surveys by themselves. From high-order control surveys to topographic data collection or fast-paced construction layout, you can rely on a FOCUS 35, even in harsh outdoor conditions.
