The very
best in wave front-sensing technology
With a recent history in working with big astronomical projects
in Europe, First Light's engineering team have combined their expertise
to offer the OCAM 2K camera - currently the fastest, low-light camera
of its type on the market.
Based in the Marseilles Astrophysical laboratory in France, and
describing themselves as a "small, reactive company",
First Light's engineers have access to two of the best photonics
clusters producing the most current technical developments in the
world, which they have translated into the design of the flagship
OCAM 2k camera.
Why is it so good?
With applications in the aeronautical, space and life science imaging
industries, the OCAM²k offers more speed, more pixels and additional
infrared sensitivity options, all contained in a compact, robust
package built for reliability.
With a speed above 2000 frames-per-second, OCAM²k is the fastest
OCAM² to date, offering 33% more speed than its progenitor,
the OCAM²-1500, and achieved by optimising and redesigning
the electronics of its predecessor to achieve this astonishing speed
without compromising the compelling, pre-existing characteristics
of the OCAM 2 family. Readout noise is still just as low with values
down to 0.1e-, Dark Signal is negligible, and latency has improved
at 43µs between exposure and first pixel availability. And
in the event that 2000 full-sized (240 x 240 pixels) images per
second not be fast enough, an optional 2 x 2 binning mode providing
120 x 120 pixels at an even more neck-breaking 3700 images-per-second
can be added. |
A unique attribute of the OCAM²k
is the inclusion of Deep Depletion Silicon feature for enhanced red
sensitivity - the only EMCCD camera to offer
this distinctive feature. |

What is EMCCD?
EMCCD sensors were designed to respond to a growing need for significantly
higher levels of sensitivity. An Electron Multiplying Charged Coupled
Device (EMCCD) is a relatively new technology platform that is capable
of detecting single photon events, without an image intensifier, whilst
maintaining high Quantum Efficiency. It is achieved with the unique electron-multiplying
structure built into the sensor. It is the combination of minimal noise
floor and high Quantum Efficiency that makes an EMCCD sensor the most
sensitive detector technology currently available.
