Princeton Instruments has launched the NIRvana:640LN, a scientific-grade camera for near-infrared and short-wavelength infrared (NIR/SWIR) applications. This new addition to the NIRvana line features a specially designed InGaAs focal plane array (FPA) that has extremely low readout and thermal noise that is ideal for ultra-low-light imaging and spectroscopy.

The NIRvana:640LN delivers a combination of less than 75 per cent quantum efficiency in the critical NIR/SWIR window along with liquid nitrogen cooling (83 Kelvin), permitting exposure times in excess of 60 minutes. The camera is suited to challenging applications in the NIR/SWIR wavelength region, such as semiconductor failure analysis, SWIR astronomy, emission microscopy and biological deep-tissue imaging.

Further features include linear, quantitative data readout as well as maintaining sensor temperature at 83K (-190°C) up to 36 hours without refilling. The NIRvana:640LN is fully compatible with Princeton Instruments’ LightField 64-bit application software; an optional package that provides complete control of camera features via a graphical user interface.

For researchers requiring a custom interface, toolkits for National Instruments’ LabView and MathWorks’ Matlab are available, as are free software development kits (SDKs). The new InGaAs camera has also been designed for easy integration with the Princeton Instruments IsoPlane 320 spectrograph.
