Spectra Precision FOCUS 35 Robotic Total Station

A powerful solution for all Forensics Applications with 1”, 2”, 3”, or 5” Angular Accuracy

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 delivers a powerful solution for all forensics applications. Packaged in a modern, sleek, streamlined design, it is easy to use, affordable and tough.

Key Features

• Available in 1”, 2”, 3” and 5” angle accuracies
• Long-range, reflectorless distance measurement
• Available RX models with extended operation dual battery system
• Trimble Forensics MFX software on-board (available models)
• GeoLock GPS-assist technology

StepDrive

The FOCUS 35 robotic total stations use patented StepDrive technology to increase the speed and precision of data collection at the scene. StepDrive controls the horizontal and vertical motion of the motors, so there is no need for traditional motion locks. The motorized drives allow users to precisely turn to, and repeat, angle measurements. The result: quick and reliable measurements, which substantially increase staking productivity.

LockNGo

The Robotic and LockNGo FOCUS 35 models include a tracking sensor that uses LockNGo technology. This enables the instrument to continuously lock onto the prism, reducing downtime, since there’s no need to repoint the instrument for every observation.

Communications Link

To maintain contact between the FOCUS 35 instrument and the user, the robotic FOCUS 35 and Spectra Precision Ranger 3 data collector use an integrated 2.4 GHz radio modem for interference-free robotic data communications. Once robotic communications have been established, you control all functions of the FOCUS 35 from the range pole as you move through the scene. This makes it possible for asingle user to efficiently create highly accurate forensic maps.

Spectra Precision GeoLock

This innovative technology enables the robotic total station to perform an aided search for an optical target using an initial GPS position. The remote instrument can then be directed towards the robotic roving operator using the GPS position and a subsequent search is quickly performed to re-acquire the target at the robotic rover. This technique greatly reduces wasted time, improving your field work efficiency. The FOCUS 35 delivers a powerful solution for all forensics applications. Packaged in a modern, sleek, streamlined design, it is easy-touse, affordable and tough.
