No imaging system is complete without a digital camera
In order to complete an PTI EasyRatioPro system, a digital camera must be selected. There are a large selection of cameras to meet your performance and budget.
Electron Multiplier CCD Cameras
The principal difference between a charge multiplying CCD and a traditional CCD is the presence of a special extended serial register called the multiplication register. This special, signal boosting process occurs before the charge reaches the readout amplifier, effectively reducing the CCD read noise by the on-chip multiplication gain factor, which can be greater that 1000x. The main benefit of the technology is a far better signal to noise ratio for signals below the CCD read-noise floor.
You would select one of these types or cameras for applications like:
- Single molecule fluorescence
- Live cell GFP imaging
Traditional CCD Cameras
These CCD’s offer excellent resolution and price/performance. High QE across visible spectrum into NIR make them excellent for monochrome imaging. A megapixel array, 20 and 10 MHz operation, Turbo 1394T interface available (FireWire®) make them a good choice for high special resolution applications.
Select one of these cameras for the following applications:
- Live-cell imaging
- High-speed emission ratio imaging
- Low-copy gene analysis and gene expression profiling
- Quantitative FRET, FRAP, FISH
Supported CCD Cameras
Many other cameras are also supported, check with your HORIBA Sales Represntative for compatibility.
High Definition Imaging Camera
The new HORIBA Lightning sCMOS camera is a breakthrough in scientific imaging cameras, due to its distinctive ability to simultaneously deliver extremely low noise, fast frame rates, wide dynamic range, high quantum efficiency, high resolution and a large field of view – all in one image.
Supreme Image Quality
The new HORIBA Lightning sCMOS camera (with scientific CMOS image sensor) features outstanding low read out noise of 1.4 electrons (e-) rms. Even at maximum speed of 100 frames/s at full resolution of 2048 x 2048 pixel the noise is less than 1.5 e- rms. Moreover, the camera provides an excellent homogeneous pixel response to light (PRNU, photo response non-uniformity) and an excellent homogeneous dark signal pixel behavior (DSNU, dark signal non-uniformity), which is achieved by a sophisticated electronic circuit technology and firmware algorithms. The lower figure shows a comparison of a scientific grade CCD and the new HORIBA Lightning sCMOS image sensor under similar weak illumination conditions. This demonstrates the superiority of HORIBA sCMOS over CCD with regards to read out noise and dynamic, without any smear (the vertical lines in the CCD image).
A 4.2 Mpixel resolution in combination with a moderate chip size (13.3 mm diagonal, 6.5 μm pixel pitch) benefits microscopy applications with low magnification factor and large field of view, thereby reducing processing times and increasing throughput. The figure compares the potential of the new field of view of the sCMOS to the 1.3 Mpixel image resolution which is widely used in microscopy applications for scientific cameras
The new HORIBA Lightning sCMOS camera offers in fast mode a frame rate of 100 frames/s (fps) at full resolution of 2048 x 2048 pixel. As in many CMOS based cameras the frame rate increases significantly if smaller regions of interest (ROI) are used. The reduction of the image area works as well in favor of the frame rate of CCD sensors, but here unwanted regions still need to be read out at the expense of the total readout speed. The typical frame rate for a 1.3 Mpixel scientific CCD camera (6 e- read out noise) is 10 fps. The new HORIBA sCMOS camera provides at 1.3 Mpixel resolution (< 1.4 e- read out noise) a frame rate of 210 fps in comparison.

Eight Page buttons and Five Rotary Encoders
Each page button can have five assignable parameters that can be edited using the rotary encoders. Page 1 encoder 1 controls the electron multiplier gain on the EMCCD camera. Other parameters can be mapped such as frames per second, experiment duration, or camera binning. Plug-In parameters can also be edited from these encoders.
