HXP51y2 Online Sensor EPG
The HXP51y2 Online EPG Sensor Head allows measurement of thinner layers than the standard HXC55yn Online Sensor Head. With higher bandwidth, and higher signal to noise, the EPG opens new applications to terahertz process control.
When connected to a T-Ray® 5000 Control Unit (TCU), the HXP51y2 provides excellent waveform response, providing detailed single-sided measurement of layered products. The HXP51y2 Online EPG Sensor Head allows measurement of thinner layers than the standard HXC55yn Online Sensor Head. With higher bandwidth, and higher signal-to-noise performance, the EPG opens new applications to terahertz process control.
The transmitter and receiver are securely mounted inside the sealed metal housing. The umbilical for the transceiver, containing the electrical and optical connections, is constructed with high flex rated electrical cable to allow continuous scanning. Coatings on metal or composite substrates and free-standing films can be measured down to 10 microns (0.5 mils).
