产品简介

详细介绍

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.



FEATURESBENEFITS
640 x 512 InGaAs arrayHigh 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 μmExcellent 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 shutterProvides 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
