Understanding Electron Multiplying Gain
Electron Multiplying CCD (EMCCD) cameras can be used to detect very weak signals, which would otherwise be lost within the noise floor of the camera. Using a conventional CCD to detect these very weak signals, usually requires both long exposure times and slow readout rates. However, EMCCD cameras can detect these same signals using much shorter exposure times and higher readout rates. This is done by applying EM gain to the signal before it...  Continue Reading..

Chemiluminescence Imaging Of Plants Using A Deep Cooled CCD
Chemiluminescence imaging combines the sensitive detection of chemiluminescence with the ability to locate and quantify the light emission. It requires high sensitivity combined with long exposure times in order to be able to detect the few photons emitted by the chemical reaction of interest with the living organisms. In a study of the circadian rhythm in plants, a deep cooled CCD camera was used with long exposure time to ensure excellent...  Continue Reading..

History And Development Of EMCCD Technology – What Is Gen III?
The earliest versions of EMCCD (Electron Multiplying CCD) sensors offered a new dimension in imaging that eliminated read noise from an image sensor. This application note provides a comparison between the first, second, and third generations of EMCCD technology.  Continue Reading..

PentaVac™ Vacuum Technology: Scientific CCD Applications
CCD imaging sensors are used extensively in high-end imaging applications, enabling acquisition of quantitative images with both high (spatial) resolution and high sensitivity. There are some photon-starved applications which require even these highly sensitive devices to be used with both long integration (exposure) times and high amounts of binning (on-chip charge summation) in order to obtain a detectable signal. For these type of...  Continue Reading..
Why Is A Backside Illuminated Sensor More Sensitive Than A Front Side Illuminated Sensor?
Why Is A Backside Illuminated Sensor More Sensitive Than A Front Side Illuminated Sensor?
Backside illuminated image sensors have fewer obstacles in incoming light's path as it reaches the pixel volume, where the conversion to charge carriers takes place. Thus, BI CMOS image sensors are able to convert more of the light into charge carriers, resulting in larger signals and better images.  Continue Reading..

Solving A Difficult Military Beam Alignment Task
Laser systems used in the periscope of a nuclear-powered submarine providing on-board instrumentation that offers accurate pitch, yaw, and roll data. As a result of the critical nature of this information, the burden is placed on the quality of the laser beam, its size, its shape, and its intensity.   Continue Reading..

The Hawk 252 is a cooled HD ultra-sensitive digital EMCCD camera offering back-illuminated EMCCD technology for enabling ultimate sensitivity imaging (<50μlux). The camera features high QE of greater than 95% at 600 nm, and GEN III image intensifier performance and enhanced blue response from 180 nm for low light UV with visible detection.

Raptor Photonics’ Kestrel is a digital monochrome scientific frame transfer EMCCD camera based on e2v’s CCD-60 back-thinned 1/3″ sensor with high sensitivity, speed and resolution, and QE up to 95%. With the EM gain on, it offers less than 0.01 electrons read noise.

The new Falcon III from Raptor Photonics is a EMCCD – GEN III camera based on e2v’s next generation CCD-351 back-thinned 1″ sensor offering 1 MP resolution with 10 μm square pixels. The Falcon provides outstanding sensitivity and speed through a single output amplifier, and is three times faster than previous generations with excellent linearity and low gain performance. Ideal applications include adaptive optics, astronomy, calcium signaling, fluorescence imaging, spectroscopy, genome sequencing, live cell imaging, and X-ray tomography.

Raptor Photonics introduces the Eagle series of -90°C 1MP and 4MP scientific CCD cameras. With featured back-illuminated CCD sensor from e2v (CCD42-40 and CCD47-10), and Raptor’s proprietary PentaVac vacuum enclosure and cooling it to -90°C, the Eagle is the perfect camera for long exposure applications.

Measurements include total luminous flux (down to 20 lm), spectrum and color parameters (CCT, CRI, TM-30-15), and flicker for a variety of applications, including automotive, traffic lighting, life sciences, and medical.

The ImagEM®X2 takes Hamamatsu’s 512 x 512 EM-CCD sensor-based camera and offers a version with four times the imaging area (without sacrificing resolution) for imaging applications with fewer than 10 photons per pixel. Its high-speed readout of 70 FPS at full resolution and 1076 FPS at sub-array 16 pixel resolution with 4x4 binning make it well-suited for capturing single images of larger molecules like proteins.

The SPOT Insight Gigabit CCD cameras combine high resolution, high frame rate, and low noise to provide superior performance for imaging applications. Recent SBIR/STTR grant recipients receive a discount on the Insight Gigabit and all SPOT cameras — learn more in the SPOT Imaging Solutions booth 131 at SPIE.

These high speed, low light imaging CCD cameras come in monochrome, color mosaic, and slider configurations. Each model features high sensitivity and fast frame rates, which helps greatly in preserving live cells and fading specimens for imaging and fluorescence applications.
