NIRvana 640
The NIRvana family of InGaAs focal plane array cameras consists of NIRvana LN, NIRvana 640, and NIRvana HS. All are designed for unrivalled performance in low light quantitative imaging and spectroscopy applications in the SWIR spectral region. The NIRvana 640 builds on Teledyne Princeton Instruments decades long experience designing the highest performance scientific cameras.
Troublesome dark noise is minimized in the NIRvana 640 with thermoelectric cooling to -85° C, enabling exposures up to 10 minutes. It offers 16-bit digitization and low read noise for outstanding dynamic range. An integrated cold shield further reduces noise by limiting the ambient thermal background.
Overview
Scientific Cooled InGaAs SWIR Camera
- Deeply cooled InGaAs detector
- 20 µm x 20 µm pixels
- 0.9 to 1.7 µm spectral range with 85% QE
- Frame rates to 110fps
- Integration times down to 2µs
- 16 bit digitization
- -85°C thermoelectric cooling
The NIRvana 640 from Teledyne Princeton Instruments is the premier thermoelectrically cooled scientific grade InGaAs SWIR camera for quantitative imaging and spectroscopy.
With deeper cooling technology than the NIRvana HS, the NIRvana 640 is the next step in sensitivity and dynamic range; enabling exposures of up to 10 minutes. With decades of experience building robust scientific cameras, the NIRvana 640 follows this tradition with an AR coated brazed vacuum window backed up by a lifetime vacuum guarantee.
