For this reason, the GEPARD™ M4 continues to be the first choice when easy and fast alignment and measurement work is involved and the highest precision is demanded. Using the real-time measurement display, objects can be aligned, adjusted and measured on-line. The user-friendly WIN-GEPARD application software automatically recognises GEPARD™ measuring devices in the vicinity and logs the results of the measuring task.
GEPARD™ Transmitter S4K (cubic)
The GEPARD laser transmitters are the reference for an exact measurement. They therefore use a highly stable fibre-coupled semiconductor laser which emits in the visible range. Because of the ingenious calibration mechanism inside the casing, fast and precise align-ment of the laser beam for measurement is ensured and the WIN-GEPARD user software makes it very easy to adjust the laser. The cubic GEPARD laser systems are extremely well suited for the measurement of planar systems (guides, surface plates etc.)
GEPARD™ Receiver E4K (cubic)
In the receiver, an optoelectronic position sensor detects the position of the focal point of the laser beam with the highest precision (1ppm resolution). Because of the use of digital signal processing, most disturbance variables from the measurement environment can be eliminated through optimum processing of the measurement data. The measurements detected in this way are transmitted to the data evaluation computer over a serial interface (using Bluetooth or fibre optics).
