Abstract: First Light Imaging’s C-RED One infrared camera is capable of capturing up to 3500 full frames per second with a subelectron readout noise. This breakthrough has been made possible thanks to the use of an e-APD infrared focal plane array which is a real disruptive technology in imagery…
C-RED One is honoured in “l’Usine Nouvelle“, the French weekly magazine, specialized in Economy and Technologies in the Industry.
The C-RED One team has received the new version of the e-APD sensor from our partner. They have integrated it into the camera, and results are fantastic:
C-RED One offers now new functions and reading modes such as correlated double sample, that were not possible before!

On October 28th 2015, at the Adaptive Optics for Extremely Large Telescopes international conference held in Lake Arrowhead, USA, First Light Imaging showed for the first time images captured by C-RED. A world record of 3507 images per second full frame with sub-electron readout noise has been achieved, while competitors are more than four times slower.
Using a revolutionary e-APD (Avalanche Photodiodes) sensor which allows noise free signal multiplication, C-RED is now the fastest scientific infrared low noise camera in the world. With its state-of-the-art high-reliability pulse-tube cooler, C-RED is completely autonomous and does not need complex cryogenics instrumentation. Its fully integrated system can operate in extreme environmental conditions and only requires simple electric power supply and water cooling. With its infrared wavelength coverage from 0.8 to 2.5 microns and unprecedented performances, C-RED can make the invisible visible.
C-RED is currently opening a new era in Astronomical, Biomedical, Industry and Defense imagery. Its commercialization is scheduled by 2016.

First Light Imaging is very proud to be on the cover of LASER FOCUS WORLD for its September 2015 issue!
Discover Jean-Luc Gach and Philippe Feautrier’s very interesting article on e-APD technology, used for C-Red One, the fastest low noise Infrared camera in the world :
Today is a big day: our team has received C-RED One’s sensor, a unique Avalanche Photodiode (e-APD) detector, 320×256 pixels HgCdTe with 24 microns pixel pitch.
Thank you to our partner!
We can’t wait to install it on C-RED’s first prototype and share our first results!
Our engineers have designed and produced the Acquisition Board, which will drive the complete system of C-RED.
Many tests are performed to check the video acquisition, without the sensor at the beginning.
We will obtain final results, and check if adjustments are needed, at the reception of the sensor.
After validating the hydraulic cooling system, and confirming the total lack of leaks and the good heat exchange between C-RED and its environment, it was time to push the limits of our cryostat.
We know now that the mechanic of C-RED is ok to be cooled down.
Our goal is to cool it down to cryogenic temperature using an integrated pulse tube: 70 kelvins (-203 Celsius degrees)
Goal achieved: our first tests with C-RED’s Cryostat show a possible cooling at 50 K (-223°C).
We now look forward to receiving our sensor, and start tests!
The team used a turbomolecular pump and made several tests to create a vacuum in the cryostat, and avoid any leak.
We succeeded and achieved expected secondary vacuum: 1.10¯⁶ (secondary vacuum goes from 1.10¯⁴ to 1.10¯⁷)
This is a huge milestone as it allows us now to check the hydraulic cooling system, and start cryogenic cooling tests.
Concurrently with the mechanical development of C-RED, our team is working hard on developing C-RED’s software, and we have now a prototype version of the soft.
All First Light Imaging’s team is really excited:
After several weeks of conception and design, we have finalized C-RED’s cryostat assembly.
We will start to test it for vacuum and cooling very soon, without sensor, nor thermal load.
These tests will allow us to validate our first mechanical prototype.

The recent discovery of electron initiated avalanche photodiodes (e-APD) using mercury cadmium telluride (MCT) semiconductor materials permitted a significant breakthrough in short wave (1-2.5 µm) infrared imaging. These diodes have an avalanche gain of up to 100 with an excess noise factor near 1, showing that the avalanche process is quasi deterministic. The hybridization of 320×256 e-APD arrays on silicon read-out circuitry permits to build imagers with fast readout rates (in the kHz range) while having at the same time a subelectron readout noise , which is a major improvement compared to previous infrared imaging technologies. The technology used to manufacture e-APDs is similar to the one used for standard HgCdTe diodes with a 100% fill factor, therefore a high quantum efficiency (typically QE=70-75 %) is maintained.
Today First Light Imaging makes this technology available to everybody: C-RED is opening a new era in terms of sensitivity and speed in the SWIR scientific cameras domain.
C-RED is using a unique 320×256 pixels HgCdTe e-APD array with 24 microns pixel pitch. The sensor cutoff wavelength is 2.5 microns and it allows sub-electron readout noise, taking advantage of the e-APD noise-free multiplication gain and non destructive readout ability. C-RED is also capable of multiple regions of interest (ROI) readout allowing faster image rate (10’s of KHz) while maintaining unprecedented subelectron readout noise.
The sensor is placed in a sealed vacuum environment and cooled down to cryogenic temperature (70K) using an integrated pulse tube, with a high reliability (MTBF > 90 000 h) much higher than standard stirling coolers used usually with cooled infrared arrays.
Initially named OCAMIR (from its big sister OCAM), the C-RED Project was born in 2014, from the idea to create the fastest low noise infrared camera in the world.
Designed and produced in France in First Light’s premises, C-RED will revolutionate the world of SWIR cameras with its unprecendented performances, identical to what OCAM² is offering in the visible.
The innovation of the C-RED project is to propose to end-users a revolutionary near-infrared camera that combines incredible frame rates (2000 fps for a 320×256 pixel format) and sub-electron readout noise at the same time by taking advantage of the revolutionary Avalanche Photo Diode (APD) detector technology made of HgCdTe (MCT) photodiodes offering noiseless amplification of the signal by single electron multiplication.
Usually, SWIR cameras are based on InGaAs technology or classical MCT technology. This does not allow to decrease the noise below a certain level (about 10 e for a double readout mode) and only at the expense of very low readout speed. Our innovation is based on the use of the new e-APD MCT technology.
First Light Imaging’s C-RED is the first camera to propose this technology.
The majority of infrared cameras use InGaAs sensors which have the advantage to be used with low cooling (higher temperatures) but are not sensitive after 1.5 µm and have a readout noise several ten times higher than C-RED. Another advantage is for C-RED to propose an embedded cooling system with no maintenance needed; most of existing cooled IR cameras are liquid nitrogen cooled and need to be refilled every 4 to 10 hours.
This means that C-RED is able to detect events that remain literally invisible for them: C-RED will make visible the invisible.
There is no existing solution providing such incredible performances. Infrared e-APD is like EMCCD in the visible, making a real technological breakthrough and permitting unexpected uses of infrared light.
