Hamamatsu ORCA-Quest II qCMOS Camera C15550-22UP with Photon-Number Resolving Technology
Product Description
The Hamamatsu ORCA-Quest II (model C15550-22UP) is a cutting-edge scientific camera based on a proprietary quantitative CMOS (qCMOS) image sensor enabling photon number resolving (PNR) capability.
- Sensor: Custom back-illuminated qCMOS sensor with 4096 (H) × 2304 (V) pixels
- Pixel size: 4.6 μm × 4.6 μm
- Effective sensor area: 18.841 mm × 10.598 mm
- Quantum efficiency (QE): Typical peak of 85%, enhanced UV sensitivity (280–400 nm) via optimized anti-reflective coating
- Full well capacity: Approximately 7,000 electrons
- Readout noise:
- Standard scan mode: 0.43 e- rms (typical)
- Ultra quiet scan mode: 0.30 e- rms (typical), enabling photon number resolving
- Frame rate:
- Standard scan: Up to 120 frames/s at full resolution (CoaXPress), 17.6 fps (USB 3.1 Gen 1)
- Ultra quiet scan (PNR mode): 25.4 fps (CoaXPress), 17.6 fps (USB)
- Exposure time range:
- Standard scan: 7.2 μs to 1800 s
- Ultra quiet scan (PNR/Raw): 33.9 μs to 1800 s
- Cooling options:
- Forced-air cooling down to -20 °C (ambient 25 °C)
- Water cooling, down to -20 °C typical, max -35 °C (water temp 20 °C, ambient 20 °C)
- Dark current:
- 0.016 electrons/pixel/s (typical) forced-air or water cooling
- 0.006 electrons/pixel/s (typical) at max water cooling
- Dynamic range: Approximately 23,000:1 (RMS typical), 28,000:1 (median typical)
- Trigger and synchronization: Multiple external trigger modes (edge, global reset edge/level, sync readout, start), SMA connectors, programmable trigger outputs and delays (0 s to 10 s in 1 μs steps)
- Data output: Raw data output for customized photon event analysis, faster edge trigger mode allows exposure start during rolling shutter readout
- Interface: USB 3.1 Gen 1 and CoaXPress (Quad CXP-6)
- Lens mount: Standard C-mount (option for F-mount available)
- Power requirements: AC 100–240 V, 50/60 Hz, approx. 155 VA
- Operating environment: 0 °C to +40 °C, 30–80% humidity (non-condensing)
- Additional features:
- Emulation modes for ORCA-Quest and ORCA-Fusion cameras
- Defect pixel correction with hot pixel correction at three levels
- Applications include: Neutral atom and trapped ion quantum computing, quantum optics, life sciences, astronomy, high-energy physics, Raman spectroscopy
- Software: Bundled interface software supports exposure control, complex triggering, and multi-dimensional experimental orchestration
- Notable improvements over predecessor: Five times faster ultra quiet scan mode frame rate, improved UV quantum efficiency, raw data output, and faster edge trigger mode
- Related resources: White paper on qCMOS technology, webinar explaining sensor innovations, and comparative studies vs. EM-CCD cameras available
This camera is engineered for research requiring ultimate low-noise sensitivity and precise photon quantification at high spatiotemporal resolution.
