Breakthrough, Back-illuminated scientific CMOS camera
KURO™, from Princeton Instruments, is the world’s first backilluminated scientific CMOS (sCMOS) camera system with up to 2048 x 2048 pixel resolution and exceptionally low 1.3 e- read noise. The KURO 1200B delivers high frame rates of 82 fps (12 bits) or 41 fps (16 bits), whereas the KURO 2048B delivers 47 fps (12 bits) or 23 fps (16 bits). These cameras are controlled by our powerful, 64-bit LightField software and are capable of delivering hundreds of fps with custom ROI. They are ideal for many challenging high speed, low-light imaging and spectroscopy applications.
Applications include:
Hyperspectral imaging | Astronomy | Cold-atom imaging | Quantum imaging | Fluorescence spectroscopy | High-speed spectroscopy
key features include:
Back-illuminated sCMOS detector with >95% peak QE
The KURO features a back-illuminated sensor architecture just like that of the most
sensitive CCD detectors available. The back-illuminated technology utilized by the
KURO allows this next-generation sCMOS camera system to deliver >95% quantum
efficiency (QE) and 100%fill factor.
Reduced fixed-pattern noise
The KURO uses the latest sCMOS fabrication technology along with optimized
electronics. As a result, it has a significantly better noise profile than any previous-
generation, front-illuminated sCMOS camera.
No microlenses on pixels
Unlike front-illuminated sCMOS cameras, which claim ~80% peak QE, the KURO
does not use microlenses to recapture light from the masked area of the pixel.
Microlenses significantly degrade QE when light is incident at any angle other than
normal to the sensor surface.
Large pixels and wide dynamic range
The 11 µm2 pixel pitch of the KURO sensor captures 2.8x more photons than
previous-generation sCMOS sensors. Each pixel can also handle a large full well
of 80,000 electrons, allowing excellent dynamic range (61,500:1 or 95 dB).
Flexible trigger modes
The KURO provides a full suite of input-output TTL signals. These signals make it
easy to synchronize camera operation with external events or light sources.
Optimized for spectroscopy
Scientific CMOS sensors typically do not support on-chip binning. However, the
KURO camera’s low read noise and support of software binning (off-chip binning)
make it ideal for high-speed spectroscopy applications. Furthermore, the pixel
pitch of its sensor is a perfect match for optimal use with the award-winning,
aberration-free IsoPlane® spectrometer from Princeton Instruments.
Powered by LightField®
Designed for operation within the Princeton Instruments LightField software
ecosystem, the KURO is easy to control and can be integrated quickly in myriad
imaging and spectroscopy experiments.Camera integration for use with both
MATLAB® (MathWorks) and LabVIEW® (National Instruments)is also fast and simple.

Rolling Shutter
Like many sCMOS sensors, the KURO sensor uses a rolling shutter mode for exposure-readout operations. This mode allows lower read noise;
however, it does not allow “simultaneous” exposure of pixels. The following diagram and table describe the rolling shutter timing used by the
KURO camera.
Effective Global Shutter
The KURO provides programmable TTL output signals that can be employed to synchronize the camera with external events or light sources.
The EXPOSE OUT signal can be programmed as follows…
FIRST ROW EXPOSE: The signal is high as long as the first row of the frame is exposed.
ANY ROW EXPOSE: The signal is high from the start of the first row exposure to the end of the last row exposure.
ALL ROWS EXPOSED: The signal is high to indicate ALL sensor rows are exposed. This is useful as a strobe pulse to control an external light
source and obtain “effective global shutter” operation.
