New, Large-Format X-Ray Cameras for In-Vacuum Applications

Princeton Instruments, the world’s leading developer and supplier of ultra-low-noise, deep-cooled scientific CCD cameras, is proud to offer our popular PI-MTE series for in-vacuum x-ray imaging and spectroscopy applications.

NEW! PI-MTE3 - Large-format, in-vacuum cameras with up to 4k x 4k sensor formats

PI-MTE3 cameras provide the following key features:

  • Back-illuminated CCDs, with up to 4k x 4k resolution and without antireflective coating
  • Sensitivity in the x-ray energy range from ~10 eV to 30 KeV
  • 100% in-vacuum testing, including cables and cooling tubes
  • High frame rates with multi-port, 16 MHz effective readout
  • Lowest dark current for long integration time
  • Advanced thermal design for 24/7 operation in-vacuum
  • Full experiment control via optional LightField software


Breakthrough In-Vacuum Performance

PI-MTE3 in-vacuum CCD cameras are engineered for direct detection in VUV, EUV, and x-ray imaging applications from ~10 eV to 30 keV.

The back-illuminated CCDs (large 2k x 2k or 4k x 4k formats) utilized by the PI-MTE3 platform offer >95% peak quantum efficiency. Efficient liquid cooling results in low dark current, facilitating long integration times.

Due to their four-port readout architecture, these low-noise, 16-bit cameras provide frame rates up to 7x to 10x higher than previous-generation two-port cameras.

X-Ray Plasma Diagnostics
Hot and dense plasmas are of enormous interest in basic physics research because of the multitude of interesting phenomena that arise from them.

Soft X-Ray Microscopy
Soft X-ray Microscopy is used for imaging and researching the elemental composition and structure of biological samples and more.

EUV Lithography
EUV lithography is gaining popularity because it retains the look and feel of the traditional optical lithography process (i.e., utilizes the 13.5 nm wavelength) and uses the same basic design tools.

X-Ray Spectroscopy
X-ray absorption spectroscopy is an element-specific probe of the local structure of elements in a material.
