Space X-ray Detector

Compact digital spectrometer

SXD is a space-rated silicon detector of ionizing radiation that serves as both a dosimeter, as well as a spectrometer. It was designed for Space and Aviation industries as a compact device for radiation measurements. Its small size, low mass, and extreme energy efficiency make SXD suitable for utilization in CubeSats, SmallSats, drones, or various handheld applications.

Availability: 12 weeks
