4. OVERVIEW
The Digital CMOS camera (C16240-20UP / C16240-20UP01) utilizes a image sensor (scientific
CMOS image sensor: sCMOS) using the latest CMOS design technologies and ultra-small
semiconductor technologies and realizes low readout noise.
The camera provides 10.5 megapixels resolution at 115 fps (frames/s) while achieving 1.0 electrons
(rms) readout noise performance.
Moreover, the adoption of the back side illuminated sensor improves quantum efficiency over a wide
wavelength range from blue to near-infrared that realizes high quantum efficiency of 86 % at the
peak wavelength. It makes the camera more suitable for high quality image acquisition in low light
level imaging than conventional the front side illuminated sensor.
Various external trigger functions and timing output functions ensure proper timing control with
peripheral equipment to cover a wide range of applications. The camera is the new scientific digital
camera for life science microscopy, semiconductor inspection, X-ray scintillator readout or industrial
imaging.
5. FEATURES
(1) Pixel number and pixel size
The Digital CMOS image sensor has 10.5 megapixels. the pixel number is about 1.98 times that
of the conventional scientific CMOS image sensor. The pixel size is 4.6 µm × 4.6 µm for high
resolution imaging and is smaller than that of the conventional scientific CMOS camera (6.5 µm ×
6.5 µm).
(2) Readout noise
The Digital CMOS camera adopts the CMOS image sensor using the latest CMOS design
technologies and ultra-small semiconductor technologies and realizes low readout noise (1.0
electrons (rms)).
(3) Quantum efficiency
The adoption of the back side illuminated and deep trench isolation technologies between pixels
improves the quantum efficiency over a wide wavelength range from blue to near-infrared with
minimum crosstalk achieving a high quantum efficiency of 51 %, 86 % and 33 % at 300 nm, 460
nm and 900 nm wavelength, respectively.
(4) Readout methods
The camera has a variety of readout modes. In addition to full resolution readout mode (1×1), sub-
array readout and binning readout (2×2, 4×4) are supported.
(5) Frame rate
This camera realizes both low noise (1.0 electrons (rms)) and high-speed readout (115 fps with
10.5 megapixels) simultaneously, by optimized and accelerated column amplifier and A/D.
(6) Cooling structure
In the camera, the CMOS image sensor is cooled down by a peltier element to suppress the dark
current. This achieves a low dark current of 0.6 electrons/pixel/s.
