Miniature 8-channel photon counter
id150 SERIES
-
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.

Photonic Hall Effect
HMS7000
-
Classic hall effect measurement system is to read voltage difference made between both diagonal sides, when flowing current and applying magnet field strength, in perpendicular to flowing current direction. - Photonic hall effect measurement is to read various electrical properties by illuminating light of “various range of wavelength” on the sample, in addition to flowing current and applying magnet field strength. - It is great to see “RGB (Red, Green, Blue), Light intensity vs carrier density, carrier mobility, resistivity, hall coefficient”

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.

Frequency Counters
-
Frequency counter models can be direct or reciprocal counters. Direct counting models count signal cycles for a specified period, called the gate time, and resolution is in Hertz. Reciprocal counters provide faster, higher resolution performance, with resolution listed is in digits/second. When shopping for a counter, remember to review resolution and accuracy as separate specifications. The resolution of a frequency counter is the smallest change it will detect between closely spaced frequencies.

Counters and Timers
-
Orbit Controls counters and timers are designed for connection to practically all industrial sensors and pulse sources . They can be used as process monitors to display the process variable to be measured or as process controllers for control and monitoring tasks. The devices display and process pulses and frequencies, as well as quadrature signals from incremental and absolute encoded rotary encoders. In addition to information on the display, the devices also generate data and analog outputs and monitor preselected limit values. The process parameters are entered via the keyboard so that the display is calibrated in the required units and the output signals, serial interfaces and limit values are optimized.

VLT-E9700
-
Modern diesel engines are quite clean, provided the soot filter is present and working properly. A soot filter can get clogged, or even malfunction. In that case the filter has to be cleaned or replaced. Unfortunately, sometimes the vehicle owner has the filter removed altogether. When the filter has been physically removed, it is ‘programmed out’ of the vehicle software, so that the removal of the filter remains undetected during an (E)OBD check. This is why in ever more countries a particle count is mandatory during a periodic inspection of e diesel vehicle.
