Xenics has introduced a high-resolution liquid-nitrogen- (LN2) cooled SWIR detector, the XFPA-1.7-640-LN2. It has been specifically developed for R&D spectroscopy and photon emission in the semiconductor failure analysis industry, high-resolution spectroscopy and low-light-level SWIR and VisNIR imaging.
The detector, based on source-follower detector (SFD) read-out technology, offers high sensitivity at a resolution of 640 x 512 pixels with a pixel pitch of 20μm. LN2-cooling at 77K provides low noise (< 20 e-) and low dark current (< 5 e-/sec per pixel).
Optionally, the measurement realm can be extended into the visible spectrum. Easy focusing on the microscope stage is supported by the increased frame rate in windowing mode. Based on this new XFPA detector, Xenics will introduce a complete camera system, the Cougar, in the second half of 2012.
