FOCUS ON... Hyperspectral imaging with C-RED 3
Hyperspectral imaging combines conventional spectroscopy and imaging to simultaneously gather spectral and spatial information. The sensitivity and speed of the C-RED 3 camera are key assets to optimize the throughput of such systems. A system running at 1200 Hz is designed and tested on standard use cases to demonstrate the feasibility of high-speed hyperspectral imaging. (In collaboration with ATIS 2.0)
FOCUS ON... C-RED 2 SWIR Extended Range
C-RED 2 ER is a highly sensitive extended short wave infrared (1300 nm – 2200 nm) camera. It is based on a VGA (640x512 pixels) ER-InGaAs detector array and offers framerates up to 600 Hz. This camera is a real breakthrough, as it is the only one with such technology on the market.
FOCUS ON... Free Space Optical Communications with C-RED 3
FSO communications are limited by a series of factors, that can be overcome by using SWIR wavelengths. C-RED 3 is a compact SWIR InGaAs camera particularly well suited to be used in an Adaptive Optics loop for wavefront sensing in a complete Free Space Optical communication system.
FOCUS ON... Understanding C-RED 3: Use cases for uncooled SWIR imaging
Numerous applications of Short Wave Infra-Red (SWIR) imaging require short exposure times, typically below 10 ms. C-RED 3 is an uncooled, compact, and cost-optimized VGA (640x512) InGaAs camera which offers high imaging performances for short exposure time imaging.
FOCUS ON: In vivo NIR-II Small Animal Imaging with C-RED 2
In vivo molecular imaging in pre-clinial animal models is key to a better understanding of physiological mechanisms. To expose the many possibilities offered by our C-RED 2 camera, an experiment in a pre-clinical imaging context was performed to dynamically map the in vivo distribution of IndoCyanine Green (ICG) in a nude mouse.
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 NAOJ -SUBARU Telescope
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.
