Chemiluminescence Imaging Of Plants Using A Deep-Cooled CCD
6/9/2020
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 to detect the few photons emitted by the chemical reaction of interest with the living organisms.

Understanding Electron Multiplying Gain
5/28/2020
Electron multiplying CCD (EMCCD) cameras can detect very weak signals that would otherwise be lost within the noise floor of the camera. While a conventional CCD requires both long exposure times and slow readout rates, EMCCD cameras use much shorter exposure times and higher readout rates.

History And Development Of EMCCD Technology – What Is Gen III?
5/28/2020
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.

PentaVacâ„¢ Vacuum Technology: Scientific CCD Applications
5/28/2020
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 applications the CCD sensor must be deep cooled in order to reduce the noise component associated with dark signal. PentaVac™ Technology from Raptor Photonics is available for a range of sensor types and formats, with a range of TECs and cooling methods which can be tailored for specific application requirements.

Why Is A Backside Illuminated Sensor More Sensitive Than A Front Side Illuminated Sensor?
10/16/2018
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.

Solving A Difficult Military Beam Alignment Task
4/1/2016
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.

Detecting And Defeating Subversive Night And Fog Activities
4/8/2013
Around-the-clock surveillance capability in any weather is a decisive operational ad-vantage for military and emergency services. In these and similar applications, SWIR cameras are well-suited for everyday use because they show good results when compared with other imaging technologies. To recognize and track objects of light-reflecting as well as self-radiating natures, SWIR cameras can be easily combined with thermal LWIR cameras and their images overlaid to enhance their content and validity.

UV Measurement Of Sunglasses Using A Back-Thinned CCD Spectrometer
1/22/2013
In assisting thousands of customers over the years, we’ve discovered that everyone has a slightly different idea of what constitutes ultraviolet light. For some, it’s the light just beyond human vision that some animals can see (300-400 nm). For others, it’s ionizing radiation that propagates only in a vacuum, below 120 nm. What we can all agree on, however, is that UV light is not good for our eyes, and that a proper pair of sunglasses needs to block these harmful rays.
