NIRvana: 640LN

??????The NIRvana: 640LN from Princeton Instruments is a scientific-grade, deep-cooled, large format InGaAs camera for low-light scientific SWIR imaging and spectroscopy applications. The camera uses a 640 x 512 InGaAs array with greater than 75% response between 1.3 μm and 1.55 μm. The detector is liquid nitrogen cooled to 83 K (-190° C) to minimize thermally generated noise and to improve signal-to-noise ratio for the most demanding SWIR applications. It offers 16-bit digitization and low read noise ??for outstanding dynamic range.????????

FEATURES	BENEFITS
640 x 512 InGaAs array	High resolution imaging in the SWIR region;Offers 4X more pixels over 320 x 256 sensor
20 mm x 20 mm pixels	High spatial resolution
Response from 0.9 μm to 1.6 μm with 70% (typical) peak quantum efficiency between 1.3 μm to 1.6 μm	Excellent SWIR sensitivity for demanding imaging applications, e.g. SWIR astronomy, semiconductor failure analysis
Liquid nitrogen (LN) cooling	Delivers lowest dark noise and allows integration time of > 60 minutes
Integrated cold-shield	Special “cold-shield" limits the ambient thermal background
Electronic shutter	Provides integration times from 100 μs to ~ 60 minutes
Two readout modes	Standard readout mode Non-destructive readout mode (NDR)
F-mount	Standard lens interface compatible with numerous lenses (spectrometer adapters available)
Fused silica window	Fused silica window for high transmission in SWIR range
GigE interface	Industry standard for fast data transfer over long distances, up to 50 m
Optional:LightField (for Windows 8/7, 64-bit) Or WinView/Spec (for Windows 8/7/XP, 32-bit)	Flexible software packages for data acquisition, display and analysis; MATLAB and LabVIEW support. LightField offers intuitive, cutting edge user interface, IntelliCal and more.
SITK for LabVIEW	Easy integration into complex experimental setup
PICAM (64-bit) / PVCAM (32-bit) software development kits (SDKs)	Compatible with Windows 8/7/XP, and Linux; Universal programming interfaces for easy custom programming.
