    AMS Technologies AG

    Dual sandwich detectors or two color detectors are mostly employed for remote temperature measurements. The temperature is measured by taking the ratio of radiation intensities of two adjacent wavelengths and comparing them with the standard black body radiation curves. The advantages of optical remote measurement have definitely made these devices the perfect match for this type of measurements. They are independent of emissivity and unaffected by contaminants in the field of view or moving targets. In addition, measurements of targets out of the direct line of sight and the ability to function from outside RF/EMI interference or vacuum areas are possible. They also have the advantages of overcoming obstructed target views, blockages from sight tubes, channels or screens, atmospheric smoke, steam, or dust, dirty windows as well as targets smaller than field of view and/or moving within the field of view. These detectors can also be used in applications where wide wavelength range of detection is needed.

  • Security/Detection

    Dexter Research Center, Inc.

    If your design challenge is to create the best motion sensor or motion detector - fire sensor or fire detector, smoke sensor or smoke detector - you've come to the right company.  Dexter's sensor technologies are at multiple fronts today, reducing the threat of combat on land, sea and air.  Yet the industry leading advantages of Dexter sensors - low cost, high sensitivity, low energy consumption and long life - make them the perfect motion sensor for home, office and facility applications. Dexter thin-film and silicon detectors can target precise threats, whether defined by movement, temperature or body mass.  Intensive MIL-STD-883H testing performed by Trialon Corporation, an independent testing facility, confirm that Dexter Research's silicon-based temperature sensor detectors meet the same rugged requirements of 1,000G's for mechanical shock and 30G's in random vibration for which our thin-film detectors are famous.  Download Dexter's report here (PDF).

    Ducommun's frequency converter families include waveguide detectors (FAS), passive and active multipliers (FMP and FMA), up and down converters (FUB and FDB), harmonic mixers (FDH), subharmonically pumped up and down converters (FUS and FDS) and phase detectors and single sideband modulators (FPB and FSS). These devices are offered in 7 waveguide bands to cover entire 18 to 110 GHz frequency spectrum. These converters employ high performance GaAs Schottky beamlead diodes and DLT's proprietary circuit configuration to produce superior performance, such as low conversion loss and up to full waveguide instantaneous operation bandwidth.

  • Laser Pyroelectric Energy Sensors

    Ophir Photonics

    Pyroelectric sensors for measuring repetitively pulsed energy at up to 25 kHz. These sensors use a pyroelectric crystal that generates an electric charge proportional to the heat absorbed. The response time of the pyroelectric sensor depends on the time it takes for the heat to enter the crystal and heat it up. For metallic type pyro detectors, this time is tens of μs and thus the metallic type can run at a high repetition rate. For the BF and BB type, the response time is milliseconds with a correspondingly lower repetition rate. Ophir pyroelectric detectors have unique and proprietary circuitry that allow them to measure long pulses as well as short pulses and work at a high duty cycle, i.e. where the pulse width is as much as 30% of the total cycle time.
