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.

Light is a collection of many photons. Photons are converted into electrons on the sensor, and these electrons are called photoelectrons. “Photon number resolving*” is a method of accurately measuring light by counting photoelectrons. In order to count these photoelectrons, camera noise must be sufficiently smaller than the amount of photoelectron signal. Conventional sCMOS cameras achieve a small readout noise, but still larger than photoelectron signal, making it difficult to count photoelectrons. Using advanced camera technology, the ORCA-Quest 2 counts photoelectrons and delivers an ultra-low readout noise of 0.27 electrons rms (@Ultra quiet scan), stability over temperature and time, individual calibration and real-time correction of each pixel value.
* Photon number resolving is unique and quite different from photon counting (More precisely the method resolves the number of photoelectrons. However, since single photon counting instead of single photoelectron counting has been used for a comparable method in this field, we will use the term “photon number resolving”).

High QE is essential for high efficiency of detecting photons and achieved by back-illuminated structure. In conventional back-illuminated sensors, crosstalks occur between pixels due to no pixel separation, and resolutions are usually inferior to those of front-illuminated sensors. The ORCA-Quest 2 qCMOS's sensor has back-illuminated structure for achieving high quantum efficiency, and trench structure in one-by-one pixel for reducing crosstalk.
What is a trench structure?
Measurement result of MTF
Modulation Transfer Function (MTF) is a type of resolution evaluation. It is the value of how accurately the contrast of an object can be reproduced.
ORCA-Quest 2 realizes ultra-low noise with 9.4 megapixels (4096 (H) × 2304 (V)). ORCA-Quest is capable of capturing a larger number of objects, compared to conventional scientific cameras like Gen Ⅱ sCMOS and EM-CCD camera.
In addition, ORCA-Quest 2 has outstanding performance in terms of its readout speed. Here, we refer to “data rate (number of pixels × frame rate)”, which represents how many pixels a camera read out in 1 second, for comparison among scientific cameras. ORCA-Quest 2 with Standard scan realizes higher data rate even with lower readout noise than conventional sCMOS cameras. Also, ORCA-Quest 2 with Ultraquiet scan realizes photon number resolving imaging with 10 times faster data rate than single photon counting imaging by EM-CCD cameras.

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.
Find detailed information in our White Paper below.
Webinar

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.

Bioluminescence
Bioluminescence microscopy has been gaining attentions because of the unique advantages against the conventional fluorescence microscopy, such as no need of excitation light.The major drawback of the bioluminescence is its very low light intensity, resulting in long exposure time and low image quality.The bioluminescence research needs highly sensitive cameras even in long exposure.

Delayed fluorescence in plants
Plants release a very small portion of the light energy they absorb for photosynthesis as light over a period of time. This phenomenon is known as delayed fluorescence. By detecting this faint light, it is possible to observe the effects of chemicals, pathogens, the environment, and other stressors on plants.

Lucky imaging
When observing stars from the ground, the image of the star can be blurred due to atmospheric turbulence therefore substantially reducing the ability to capture clear images. However, with short exposures and the right atmospheric conditions, you can sometimes capture clear images. For this reason, lucky imaging is a method of acquiring a large number of images and integrating only the clearest ones while aligning them.

Adaptive optics
Adaptive optics is a method where systems immediately correct the wavefront of incoming light which is disturbed by atmospheric fluctuations. In order to perform real-time and highly accurate wavefront correction, a camera needs to get images with high speed and high spatial resolution. In addition, the camera also needs high sensitivity because the wavefront correction is performed in a very dark condition where a laser guide star is measured.
