Description
The ORCA-Quest is the world’s first camera that achieves the ultimate in quantitative imaging by photon number resolving, with a qCMOS image sensor developed using Hamamatsu’s unique design technology and the latest manufacturing techniques. ORCA-Quest had achieved the level to realize photon number resolving owing to ultra-low noise characteristic in ultra quiet scan mode. However, this availability was limited for users because the ultra-low noise was available only when the camera operated in 5 frame per second (in full resolution).
ORCA-Quest 2 has achieved 5 times faster framerate with a similar ultra-low noise characteristic by optimizing the sensor operation. Photon number resolving feature has become available for most of users now! Inspired by market needs, ORCA-Quest 2 has achieved even higher UV QE by optimizing AR coating of the sensor window, with no change of visible, near infrared wavelength region. The QE improvement expands the versatility of ORCA-Quest series in many kinds of application such as trapped ion quantum experiment. In order to detect weak light with high signal-to-noise, ORCA-Quest 2 has been designed and optimized to every aspect of the sensor from its structure to its electronics. Not only the camera development but also the custom sensor development has been done with latest CMOS technology, an extremely low noise performance of 0.30 electrons has been achieved.
The ultimate quantitative imaging with the qCMOS cameras is expected to find applications in various fields, including quantum technology, astronomy, semiconductors, and life sciences.
Webinar
We are at the dawn of a new era in CMOS and scientific imaging technology. To fully appreciate why the release of our new ORCA-Quest quantitative CMOS (qCMOS) camera with photon-number resolving technology is an engineering feat that can enable new paths of discovery in biology, physics, astronomy and quantum research, we invite you to watch our launch-day webinar by Dr. Peter Seitz.　Dr. Seitz will briefly review the history of semiconductor image sensors and the principles of sensor design and show how applying the principles of photon and camera noise combined with advances in semi-conductor manufacturing culminated in the world’s first qCMOS technology. Laurin Publishing Company, Inc. are producers and owners of the recording from May 19, 2021.
