T-Ray® 5000 Control Unit for Industrial, Nondestructive Testing, and Scientific Applications

The T-Ray® 5000 Terahertz Control Unit is best suited for scientific applications and industrial, non-destructive testing. The system is capable of monitoring and controlling all aspects of terahertz (THz) generation and detection.

The control unit offers accurately controlled optical signals to the terahertz transmitters and receivers, or the T-Gauge® Sensor Heads. This allows them to produce and receive terahertz signals. The control unit processes the measured data at a rate of 1 kHz, which makes the T-Ray® 5000 one of the fastest terahertz systems currently available.

The data produced by the T-Gauge® Sensor Heads and processed by T-Ray® 5000 Control Unit facilitates simultaneous, multiple measurements of products.

One T-Gauge® Sensor is designed to measure the caliper thickness, basis weight, density, multi-layer thickness and moisture content of a sample in a single measurement.

The T-Ray® 5000 Control Unit is attached to a separate transmitter and receiver, enabling it to perform not just spectroscopic measurements but also transmission and reflection imaging.

The T-Ray® 5000 Control Unit and its accessories are connected with robust connection points and interfaces well suited for the industrial environment. The system is assembled with enough connections to facilitate smooth integration with a majority of the QC systems or experimental applications. The industry-standard interface connections ensure easy integration with the T-Gauge® Sensor.
