Pin Diode Based X-ray Detector

    From alignment of laboratory devices to long term monitoring of X-ray intensity

    The Rigaku xPIN metrology detector is a PIN diode based EUV / X-ray detector featuring compact and flexible design ideal for various applications ranging from alignment and testing of laboratory devices to long term precision monitoring of X-ray intensity. Due to its affordable price and user friendly operation, it is an ideal professional tool that shouldn’t be missing in any X-ray laboratory or X-ray service engineer’s tool bag. 

    xPIN Overview

    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. Recharging or power supply operation can be done through standard USB cable from any USB device. While connected to PC the USB cable serves also for data transfer. Various sensor types and filter foils enable to use the Rigaku xPIN for a broad range of energies covering EUV to X-ray radiation.

    Several diodes types available:

    • X-ray range air version
    • X-ray range vacuum compatible detector housing
    • EUV range – pulsed source
    • EUV range – continuous source
    • Other diode types available upon request
