NIRvana LN
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 LN builds on Teledyne Princeton Instruments decades long experience designing the highest performance scientific cameras.
Troublesome dark noise is all but eliminated in the NIRvana LN with cooling to -190° C, enabling exposures of over 1 hour. 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 1.5 µm spectral range with 87% (max)QE
- Frame rates to 2.77 fps
- Exposure times of over one hour
- 16 bit digitization
- -190°C cooling
The NIRvana LN from Teledyne Princeton Instruments is the premier cooled scientific grade InGaAs SWIR camera for quantitative imaging and spectroscopy.
With deeper cooling technology than either the NIRvana HS, or NIRvana 640, the NIRvana LN is the next step in sensitivity and dynamic range; enabling exposures of over 60 minutes. With decades of experience building robust scientific cameras, the NIRvana LN follows this tradition with an AR coated brazed vacuum window backed up by a lifetime vacuum guarantee.
