FOCUS ON: Long exposure times optimization with C-RED 2

Long exposure time in short wave infrared (SWIR) imaging is complex. It allows to detect and image very weak signals, but most of the existing SWIR cameras are confronted to physical limits. C-RED 2 is a SWIR 640x512 InGaAs camera which offers smart parameters tuning possibilities and optimizes the acquisitions for long (over one second) and very long exposure (over one minute).

Characterization of the C-RED 2: a high-frame rate near-infrared camera

Abstract. A wave of precision radial velocity (RV) instruments will open the door to exploring the populations of companions of low-mass stars. The Palomar Radial Velocity Instrument (PARVI) will be optimized to detect RV signals of cool K and M stars with an instrument precision floor of 30 cm∕s. [...] We describe the performance of the PARVI guide camera: a C-RED 2 from First Light Advanced Imagery.

C-RED 2 : Imaging single carbon nanotubes (L.Cognet)

Abstract: Here, we show that the First Light C-RED2 InGaAs camera cooled to -40°C and mounted on a fluorescence microscope is capable of detecting single (6,5) SWCNTs immobilized on a glass slide at 25 frames per second, 125 frames per second and up to 250 frames per second (4ms exposure per frame).

SWIR Fluorescence in Life Sciences

SWIR Fluorescence in Life Sciences: a glimpse on new biomarkers imaging. Living tissues have capability to absorb and scatter photons at different depth, depending on light wavelength. Recently, the shift to higher wavelength fluorescence imaging in Short Wave Infrared (SWIR or NIR II i.e.1000 to 1700nm) region has drawn great attention worldwide.


SCExAO: Directly imaging exoplanets with large ground-based telescopes critically relies on high performance cameras to accurately measure atmospheric turbulence and detect the faint planet signal.

First Light Imaging’s C-RED One is looking at the sky!

MIRC-X, the 6-telescope beam combination instrument developed by the University of Exeter (UK) and the University of Michigan (USA), together with C-RED One, the world’s fastest low noise infrared camerafrom First Light Imaging, are opening new perspectives in Infrared Interferometry for Astronomy.
