Princeton Instruments (Trenton, NJ) has introduced the NIRvana:640LN, a high-performance 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 for ultra-low-light imaging and spectroscopy.

The NIRvana:640LN delivers a combination of >75% quantum efficiency in the critical NIR/SWIR window along with the deepest liquid nitrogen cooling (83 Kelvin) currently achievable for an advanced InGaAs FPA, permitting exposure times in excess of 60 minutes. The camera’s performance facilitates such challenging applications in NIR/SWIR wavelength region as semiconductor failure analysis, SWIR astronomy, emission microscopy, and biological deep-tissue imaging. Other features beneficial to scientific researchers include linear, quantitative data readout, as well as maintaining sensor temperature at 83 K (-190°C) up to 36 hours without refilling.
