Sciencetech's Area CCD detector systems can be used in imaging spectroscopy applications, such as simultaneous multi-spectra spectrometry, or in typical spectroscopy applications such as fluorescence and Raman spectroscopy by operating in line binning linear mode. Being a complete detector system with easy to integrate Windows Active-X software, it can be adopted to new and existing spectrographs for applications that require low light level detection within the 200-1100nm(UV-Infrared) spectral range for Back Thinned Versions and 400nm-1100nm for Front Illuminated Versions. System Components Detector system includes sensor head by Hamamatsu, power supply, 16-bit A/D data acquisition board for PCs, Sciencetech's SCI-LDA Active-X real-time data acquisition software, cables and optional mechanical shutter Models Available Sciencetech's Area CCD detector systems are available in different sensor sizes (512 x 60, 512 x 124, 512 x 252, 1024 x 60, 1024 x 124, or 1024 x 252), with optional back-thinned versions (having slightly smaller pixel counts) that have high quantum efficiency (up to 90% compared to 40%) and high UV sensitivity, optional thermal electric Peltier cooler (to 10°C for superior low level light detection), and optional twin blade mechanical shutter (10 ms response time). Spectrograph Compatibility Sciencetech CCD detectors can be mounted on the exit port of any flat field spectrograph, and not just those manufactured by Sciencetech. Custom adapter plates for mating Sciencetech CCD detectors to non-Sciencetech spectrographs are available, making it a viable upgrade option. Sciencetech CCD detectors can be mated to all Sciencetech spectrograph models. Detector Data Acquisition Software Sciencetech's SCI-LDA software is an MS-Windows based Active-X data acquisition application that captures real-time spectral data from Sciencetech's linear photo-diode array detectors and CCD detectors. In CCD linear scan mode, all pixels are vertically binned together to produce one linear array of 512 or 1024 elements before they are acquired. In CCD area scan mode, the entire 2D array is acquired as separate pixels, but can be segregated in to individual or "groups" of pixel rows, each acting as a separate linear array channel for display and analysis purposes. The acquisition software displays the real-time spectral data in graphical format, which can be printed, saved as a bitmap image, or saved as a series of data points in ASCII format for importation in to a third party analytical software. Users can also customize the graphical display such as set scale factors, axis units (wavelength vs. wave number), magnification, and even centering of data around grating position. Detector functions such as integration time, input voltage scaling, shutter control and cooling (if available) can also be set through the software. Active-X based controls allows such features to be incorporated in to custom software applications. Optional Shutter Sciencetech's mechanical shutter is a modular component that mates right in front of the sensor head. It can also be placed inside the spectrograph if the focal plane alignment does not permit it to be mounted in front of the sensor.

Mating to Non-Sciencetech Spectrographs Sciencetech CCD detectors can be mounted to any flat field spectrograph using a custom designed adapter plate. Since knowing the exact location of the focal plane at the spectrograph exit slit is required, Sciencetech recommends sending the spectrograph to its facilities for CCD detector mating.
