Promis Electro-Optics introduces Centronic mid infrared detectors, hybrid silicon photodiodes, electron photodiodes and semi conductor radiation detectors

applications

• gas sensing
• optical pyrometry
• flame measurement
• eyesafe designator detection
• radiometry
• scanning electron microscope backscatter (SEM) detection
• scanning transmission electron microscope (STEM) detection
• electron beams 1keV-30keV

midrange infrared detectors

The Centronic 9IR infrared photodiode is suitable in a 1.8-2.3 µm range by using GaAsSb/GaInAsSb hetero structures during the production process.

Packaging options include standard TO housings with or without thermoelectric cooling as well as chip on board.

hybrid silicon photodiodes with integrated preamplifier

PEO introduces the new generation hybrid silicon photodectectors (Amplified Single Element Detector – ASD) of Centronic. The ASD combines a high performance single element photodiode with a high input impedance op-amp for signal detection with high gain and low noise.

When light hits the detector this results in directly measurable voltage.

charged particle detector

Centronic charged particle detectors are silicon diodes fabricated with a specially minimized dead layer to ensure maximum charge is deposited in the depletion region of the device.

For electron detection in microscopy applications a quadrant geometry is offered with a 140μm diameter hole trough which the primary electron beam can pass.

We are interested in your geometry, active area configuration and detector hole size for your specific application

semiconductor radiation detectors

Centronic expanded her expertise from the silicon photodiodes into detection of x-ray.

X-ray detectors utilize silicon photodiode technology and with the addition of a scintillation crystal or membrane of scintillation material. This combination enables to shit the higher energy x-ray into the visible spectrum, which is directly detectable by a photodiode.

There are a variety of scintillator materials available such as Caesium Iodide (CsI), Cadmium Tungstate (CdWO4) crystals and Gadolinium Oxide membranes.

• Scintillators are optionally available in one of the following available materials with thickness adapted to the energy field.
• It is possible to shield the detectors from ambient light by adapting the design of the housing to your application.
