xPIN-TM Diode Metrology Detector

RITE completes its portfolio of detectors by offering users a metrology PIN diode detector called the xPIN™.  The xPIN™ features a compact and flexible design ideal for applications ranging from alignment and testing of laboratory devices to long term precision monitoring of X-ray intensity and is the ideal solution when intensity monitoring or beam alignment is of importance.

The detector can be easily used as a hand-held monitor or can be used with the sensor head fixed to the optical bench.  The detector has its own long life internal battery. The recharging or power supply operation can be done through a standard USB cable from any USB device.  While connected to the PC, the USB cable also serves to transfer data.  Various sensor types and filter foils enable the xPIN™ to be used for a broad range of energies covering EUV to X-ray radiation.

The xPIN™ is available to cover a wide range of energies from EUV/XUV to Hard X-rays. While the xPIN™ typically gives a relative intensity value, a calibrated version is available.  Finally, for EUV applications both pulsed and continuous versions are available.
