Hamamatsu ORCA-Quest II qCMOS camera C15550-22UP
Groundbreaking in concept and unprecedented in performance.
Since the 1980s, Hamamatsu Photonics has continued to develop high-sensitivity, low-noise cameras using its unique camera design technology and has always contributed to the development of cutting-edge scientific and technological research. The ORCA-Quest is a camera with a qCMOS image sensor developed using our unique design technology and the latest manufacturing techniques. It is also the world's first camera that achieves the ultimate in quantitative imaging by photon number resolving.
Evolution from ORCA-Quest
Faster ultra quiet scan mode
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!
UV QE improvement
ORCA-Quest possessed high quantum efficiency (QE) in UV region around 280 nm-400 nm, compared to most of conventional scientific cameras.
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.
Raw data output
The feature allows you to apply any algorithms to estimate the number of photoelectron from raw digital signal.
Faster edge trigger mode
The new edge trigger mode enables you to input an external trigger and start exposure during rolling shutter readout, resulting in a faster frame rate.
Four key features
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.

White paper
The evolution of imaging technology is directly linked to new scientific achievements. Scientific imaging has moved many experiments from relying on subjective recording into objectively documentable, repeatable, and quantifiable methods. Demanding and extremely valuable techniques such as single-molecule-based methods would not be possible without appropriate image sensors. The novel quantitative CMOS (qCMOS) technology finally reaches the physical limit: reliable quantification of photon numbers within each pixel, eliminating the influence of technology on the “triangle of frustration” (resolution, sensitivity, speed). This white paper discusses the new image sensor technology that is at the heart of the qCMOS camera. Topics include the semiconductor image sensor, the state of the art approaches to quantitative semiconductor image sensors, The qCMOS image sensor, and the challenges for photon number resolving.

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.

qCMOS camera vs. EM-CCD camera – Performance comparison of Photon counting cameras
The qCMOS camera is positioned as an ultra-sensitive camera that offers the ultimate in quantitative imaging because of its extremely low noise performance. Therefore, when comparing a qCMOS and EM-CCD camera it is necessary to judge which camera is best suited to your application.
The purpose of this article is to compare qCMOS and EM-CCD cameras to help you choose the best camera for your application.
Applications
Neutral atom, Trapped ion
Neutral atoms and ions are aligned one by one in an array to be utilized as Qubits for Quantum computing. The qubit states can be determined by observing the fluorescence from each of them. The measurement of the fluorescence needs to be done in short time and then photodetectors with very low noise and high speed are needed. ORCA-Quest 2 can do both of diagnosis of the whole qubit array and state detection of each qubit with very low noise characteristics and high speed readout. Also, the QE covers wide range of wavelength for major ion and atom species.

Quantum optics
Quantum optics uses single photon sources to make use of the Quantum nature of the single photon.The quantum optics research also uses single photon counting detectors, and now there are emerging needs of photon number resolving detectors to distinguish photon numbers coming into the detectors.A photon counting camera, a new concept in camera technologies, is expected to make a new discovery in this field.
