4. OVERVIEW
C13440-20CU / C13440-20CU01 is equipped with the new scientific image sensor, an advanced
CMOS device that realizes the multiple benefits of high resolution, high readout speed, and low
noise all at once.
The camera provides 4.0 megapixels resolution at 100 fps (frames/s) (and up to 25 655 fps by
sub-array readout) while achieving 1.0 electrons (median) 1.6 electrons (r.m.s) readout noise
performance. Moreover, the camera delivers high sensitivity through its on-chip micro lens, 37
000:1 high dynamic range that makes the camera suitable for almost any scientific application from
bright field imaging to low-light fluorescence imaging across a wide spectral range. 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) Readout noise
In the camera, the pixel amplifier is optimized: it has high gain from optimizing the semiconductor
process, and the difference among pixel amplifiers are greatly minimized. In addition, there is
on-chip CDS (correlated double sampling) circuit, which plays an important role in achieving low
noise. Moreover, the sensor features a split readout scheme in which the top and bottom halves
of the sensor are readout independently, and the data of each horizontal line is read by 2 lines of
column amplifier and A/D in the top and the bottom in parallel and simultaneously. As a result, it
achieves very fast readout speed while keeping very good low-noise performance.
The camera has lower readout noise (1.0 electrons (median), 1.6 electrons (r.m.s)) than the
conventional cooled CCD camera. Moreover, high-speed readout (100 fps with 2048 pixels ×
2048 pixels) with very low readout noise, which was impossible, can now be achieved.
In addition, the camera can achieve further lower readout noise (0.8 electrons (median), 1.4
electrons (r.m.s) with slow scan mode (30 fps with 2048 pixels × 2048 pixels).
(2) Cooling structure
In the camera, the CMOS image sensor is cooled down by a peltier element to suppress the dark
current. If the CMOS image sensor is exposed to the atmosphere, condensation of the moisture
from the air might occur. However the camera has a special hermetic chamber structure to isolate
the sensor from the atmosphere, and the chamber is filled with nitrogen gas.
(3) Pixel number and pixel size
CMOS image sensor has 6.5 µm x 6.5 µm pixel sizes that is equivalent to conventional CCD
image sensor (2/3 inch, 1.3 megapixels). Also, the camera can observe a wider field of view
because the pixel number is about 3 times that of the conventional CCD image sensor (2/3 inch,
1.3 megapixels)
(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
CMOS image sensor which this camera adopts realizes both low noise (1.0 electrons (median)
1.6 electrons (r.m.s)) and high speed readout (100 fps with 2048 pixels x 2048 pixels)
simultaneously, by a split readout scheme in which the top and the bottom halves of the sensor
are readout independently, and the data of each horizontal line is read by 2 lines of column
amplifier and A/D in the top and the bottom in parallel and simultaneously.
(6) Real-time correction functions
There are a few pixels in CMOS image sensor that have brighter or darker intensity, and a few
pixels that have slightly higher readout noise performance, when compared to surrounding pixels.
The camera has a real-time variant (defective) pixel correction feature to further improve image
quality. The correction can be performed in real-time without sacrificing any of the readout speed.
(7) Data reduction functions
The camera provides a maximum 4.0 megapixel resolution at a rate of 100 fps and with 16 bit
intensity levels per pixel. With these conditions, the camera outputs 800 MB of data per second,
making it necessary to store a large amount of data. With data reduction functions now
available in the camera, it is possible to select reduced areas of the image and/or reduced
intensity levels to transfer and store only the data of interest.

C13440-20CU / C13440-20CU01 Instruction manual_Ver.1.3

(8) Interface
This camera has both Camera Link and USB 3.0 interface.
Camera Link Interface:
The camera Link interface is able to transfer large volumes of data. It can transfer a 4 megapixels
image with 100 fps.
In order to realize such a large volume data transfer, the camera uses Camera Link "Full
Configuration Deca Mode" which is an expanded version of Camera Link "Full Configuration". It
enables a transfer maximum 85 MHz x 10 Taps (8 bit) image data to computer as fast as 100 fps.
In order to use this interface, a Camera Link interface board which supports "Full Configuration
Deca Mode" is required.
USB 3.0 Interface:
USB 3.0 interface is able to transfer a 4 megapixels image with 40 fps. It is versatile interface
which is suitable to use when fast data transfer is not required.
This interface does not require a Camera Link interface board. It transfers image with moderate
transfer speed.
• When a connection interface is changed from Camera Link to USB 3.0, and vice versa, the
application software must be closed and the camera must be turned off.
• Do not connect Camera Link and USB 3.0 interface simultaneously.
(9) Camera readout modes
The camera has four kinds of readout mode, Normal Area Mode, Lightsheet Readout Mode,
W-VIEW Mode and Dual Lightsheet Readout Mode. The camera also has two scan speed in
Normal Area Mode and W-VIEW Mode, and two readout direction in Lightsheet Readout Mode,
W-VIEW Mode and Dual Lightsheet Readout Mode.

(10)Camera operation modes
The camera has three operation modes: 1) Free running mode, in which the exposure and
readout timing are controlled by the internal microprocessor, and 2) External trigger mode, in
which the exposure and readout timing are decided by an external trigger. 3) Start trigger mode is
used to start operating the camera by a trigger input for a continuous imaging.

8. WATER COOLING
• Improper handling of the camera without observing these cautions could lead to
personal injury to the user or damage to property.
8-1 CAUTIONS
(1) Change the cooling method
The default setting of cooling method is Air-cooling. Cooling mode can be changed by software
which is called, “DCAM Configurator”. (refer to 9-5 “STARTUP DCAM CONFIGURATOR”).
(2) Cooling water
It is recommended to use soft water (except pure water) for cooling water.
If you plan on using water other than soft water as recommended for example antifreeze etc,
please refer to description of cooling water which is written in 12. “MAINTENANCE” or contact a
Hamamatsu subsidiary or your local distributor.
(3) Recommendation temperature
Hamamatsu recommends 20 °C for Circulating water temperature.
For the appropriate temperature range of the cooling water, confirm with the instruction manual of
your circulating water cooler.
(4) Condensation
Use the camera under the environment where condensation will not take place referring to the
following graph.
