The XPIN®-BT X-ray Detector from Moxtek represents one of the most capable Si-PIN detector solutions available for analytical X-ray instrumentation. Built around a 625 µm thick silicon PIN diode with an ultra-low-noise JFET preamplifier and a multi-layer collimator, this detector achieves high energy resolution and sensitivity for accurate elemental analysis in demanding applications.
Key Features & Technology
- High-Performance Si-PIN Diode: The thick silicon PIN diode delivers enhanced photon absorption and energy resolution, enabling precise detection of X-ray signals across a broad energy range.
- Internal Two-Stage Thermoelectric Cooling: Built-in thermoelectric cooling eliminates the need for external cryogenics (no liquid nitrogen), ensuring stable performance and low noise over time.
- DuraBeryllium® Window: A thin, corrosion-resistant beryllium window with proprietary DuraCoat® protects the detector while maintaining efficient low-energy X-ray transmission.
- Compact & Portable Design: The BT (“Benchtop/Temperature-controlled”) package is designed for easy mounting in portable and benchtop systems, with simple integration and automatic internal temperature control.
- Vacuum-Sealed Construction: Vacuum encapsulation enhances thermal stability and detector longevity, supporting consistent performance in industrial or field environments.
