Overview
The first detector to bring 0D-1D-2D and 3D data to your diffractometer
The PIXcel3D is a unique 2D solid-state hybrid pixel X-ray detector. Each pixel is 55 microns x 55 microns and the detector array is 256 x 256 pixels. The detector, now based on Medipix3 technology, brings unrivalled signal to noise with its point spread function of one pixel and multiple energy discrimination levels.
Medipix3 technology brings:
- An increase in range of detection energies from Cr to Cu
- Improved energy resolution
- Increased linearity range
- Improved detection efficiency
- Documented (published) radiation hardness studies.
