QE system provides electronics and software designed for fully automated measurement of external quantum efficiency of solar cells. All systems include probes and a fixed plate sample stage for samples up to 150 mm x 150 mm. The main system components include: custom designed software, measurement electronics, and computer system (Windows 8 operating system). The measurement involves focusing monochromatic light to a spot on the device under test, then accurately measuring the photon flux and current from the test cell. The system utilizes a dual beam configuration with lock-in detection, providing an absolute accuracy of ±3%. The QE system uses a grating monochrometer with silicon/InGaAs/Ge detectors. The system includes automatic order sorting filters and two light sources for monochromatic illumination (a Xenon- arc lamp and a halogen lamp). A single lock-in amplifier is used to measure both the reference detector and test device. The main system comes with all the hardware needed to measure quantum efficiency, a fixed plate sample stage and probes.

Photon Counting Cameras
-
Photek photon-counting camera systems are unique as they provide the ability to capture and integrate an image in real time. These systems are ideal for extremely low photon emission applications such as bio-luminescence, chemi-luminescence and weak fluorescence. The ability to accurately analyze transient events is a key feature of this product. The length of time that the image can be integrated is limited only by disc space, and allows the user to fully capture real-time events. X, Y and time co-ordinates for post acquisition analysis is also recorded. X-ray and vacuum imaging camera options are also available.

Intended for large-volume OEM applications, the id150-1x8 is the only multichannel solid-state single photon detector on the market. It consists of a CMOS silicon chip packaged in a standard TO8-16pin header with a transparent window cap. The chip combines 8 in-line single photon avalanche diodes that can be accessed simultaneously for parallel processing. square in center-to-center A fast active quenching circuit is integrated within each pixel in order to operate each diode in photon counting regime. The chip is mounted on a printed circuit board on top of a single-stage thermoelectric cooler (TEC). A thermistor can be used to measure the temperature of the chip. Only two low power supplies of +5V and -25V are needed for operation in photon counting mode. The fast active quenching circuit leads to a dead time of less than 50ns per channel. An outstanding timing resolution of less than 60ps allows high accuracy measurements.
