Neutron Detectors
-
As a neutron has no charge, a neutron detector incorporates a neutron-to-ionisation particle converter.The incident neutrons are captured by the converter material which then produces (detectable) ionising particles by means of a nuclear reaction.Photonis gas-filled detectors are designed to detect thermal neutrons (En < 0.025 eV), so the capture cross-section of the detecting material must be as large as possible for this low energy. We therefore use 235U (580 barn at 20 °C) for our fission chambers, and 10B (3840 barn at 20 °C) for our boron-lined proportional counters.

RMS Responding Power Detectors
-
Recognized as the pioneer and leader in RF detectors, Analog Devices offers a broad portfolio of high performance logarithmic amplifiers and TruPwr™ rms responding detectors. ADI logarithmic amplifiers measure signals up to 100 dB dynamic range, from dc to microwave, and accuracies of ±0.2 dB, and are well-suited for both RSSI and transmit power level detection. The TruPwr rms detectors address the challenge of measuring complex waveforms found in spread spectrum CDMA/W-CDMA and higher order QAM modulation systems and provide an accurately scaled dc voltage, which is the rms equivalent of the input waveform.

Metal Detectors

In our ever-changing landscape, important assets are buried or paved over making finding for them both difficult and time consuming. Valve and manhole covers are often lost after ground work activities, re-surfacing or after heavy snow falls. Buried boundary markers can also be difficult to find. Most of these items are manufactured using magnetic or ferrous materials. These can be detected using the VM-880. As it detects only ferrous materials, aluminum cans, bottle caps, etc. are rejected. The simple audio and visual user interface has been designed to minimize training requirements while the latest technologies are employed to ensure maximum sensitivity and depth range. Particular attention has been made to ensuring the weight of the VM-880 is minimized, at just 1.54lbs (0.7kg), it is by far the lightest in its class. This has been achieved without compromise to strength. The submersible carbon fiber antenna tube is both lightweight and provides maximum protection to sensitive sensors.

Radiation Detectors
-
A radiation detector is a device for measuring nuclear, electromagnetic or light radiation. A nuclear radiation detector identifies nuclear radiation by measuring the emission of ionizing radiation of alpha particles, beta particles and gamma rays. Also referred to as a geiger counter, a nuclear radiation detector consists of two main elements: the processing electronics and the geiger tube. The geiger tube is filled with low-pressure inert gas like helium, argon or neon. If radioactive radiation occurs, the inert gas is ionized. An anode within the geiger tube registers the quantity of ionized particles numerically correlating with the strength of the radioactive radiation. The radioactivity measurement is then displayed on the LCD screen of the geiger counter or nuclear radiation detector.

Besides the described types Inphora can supply detector-filter combinations with parameters matching the customer's special requirement, with different sized housing, without housing. If the application determines the detector's spectral responsivity, we can achieve that with a filter designed exactly to the specifications. CCD cameras with unusual spectral sensitivity functions can be matched with filters to obtain CIE tristimulus response or photopic response. Similarly, photmultiplyers can be matched also with INPHORA filters. When determining parameters for a custom detector-filter combination several details have to be considered:
