X-ray sCMOS 37.7MP Detector

18 Feb 2021

The detector offers a round 61.44 x 61.44 mm active area, fibre optically coupled to a single chip with 37.7-megapixel resolution. A custom scintillator is deposited onto the fibre optic input to allow 1keV up to 100keV operation. 

The X-ray sCMOS detector delivers up to 11 fps full-resolution allowing real time acquisition routine. A built-in electronic shutter allows shutterless acquisition even with exposure time down to  less than 100 microsecond range. Frame rate of greater than100 fps can be achieved when used in local sub area mode or line scan mode. 

A soft X-ray version with detection down to VUV will be made available for low energy applications down to few 100eV. 

A device server driver control allows remote acquisition through existing GUI interface, allowing easy integration within existing synchrotron or laboratory software.  

The detector is part of a larger product range featuring the same very low noise performance and small pixel size achieving very high-resolution imaging. 

The active area offered by these new devices ranges from 22.5 x 22.5mm, 36.8 x 36.8 mm up to 61.5 x 61.5mm with resolution from 2048 x 2048, 4096 x 4096 up to 6144 x 6144 pixels respectively using 1:1 fibre optic coupling between the sensors and scintillator material. 

All these X-ray sCMOS detectors will achieve single-photon detection sensitivity. A larger active area can be reached using demagnifying tapered fibre optic and/or detector tiling. 

Scintillator CsI:Tl materials with needle-like structures offer very good absorption efficiency whilst maintaining good spatial resolution up to 100keV. Other conventional materials such as GdOS:Tb is used for low energy applications up to 50keV.
