InGaAs Camera for Spectroscopy and SWIR Imaging - NIRvana®

The NIRvana® family of focal plane array (FPA) cameras, offered by Princeton Instruments, consists of the NIRvana, NIRvana LN, and NIRvana ST cameras. These are the only scientific-grade InGaAs cameras on the market particularly designed for quantitative near-infrared (NIR) / shortwave-infrared (SWIR) imaging and spectroscopy applications.

The NIRvana: 640

The NIRvana: 640, the world’s first deep-cooled, scientific grade, large format InGaAs camera available from Princeton Instruments, is designed for low-light scientific SWIR imaging and spectroscopy applications. This camera uses an InGaAs 640 x 512 array with response from 0.9 µm to 1.7 µm. The detector is Peltier cooled to -85 °C to achieve improved signal-to-noise ratio and to reduce thermally generated noise for the extremely challenging SWIR applications. It provides 16 bit digitization and low read noise for excellent dynamic range.
