  • Finline Detectors

    950 Series - Milimeter Wave Products, Inc.

    Mi-Wave’s 950 Series Detectors convert incident RF energy into a DC voltage signal. The function of these detectors is similar to power sensors, with two exceptions. The 950 Series detectors perform measurementsmore quickly and have a greater dynamic range than that obtainable from comparable power sensors.

  • Cable Detectors

    PCE Instruments

    With certain models of cable detectors you can locate open power cables, either live or dead (without current), with voltages up to 300V. Cable detectors can locate cables, circuits, short circuits and ground points. To perform these functions it is not necessary to disconnect electrically sensitive devices or to disconnect theCable Detectors to locate open power cables, either live or without current, up to 300V. power from the cable which is being tested. Cable detectors can also locate ferrous and non-ferrous metals, wood and plastic with a high level of accuracy.

  • Broadband Detectors

    Pacific Millimeter Products

    These waveguide bandwidth detectors use silicon beam lead diodes on a planar stripline circuit to obtain an extremely rugged and compact device. Most millimeter wave broadband detectors have very poor VSWR due to the difficulty in obtaining a good wideband impedance match to the diode. To overcome this problem, these detectors utilize two diodes and an internal matched termination and 3 dB hybrid as shown below. This circuit allows a VSWR of 2.0 or better over a full waveguide bandwidth for most of these detectors. Detectors for waveguides WR-8 and smaller use a single zero bias GaAs diode.

  • Waveguide Detectors

    Keysight Technologies

    These GaAS planar-doped barrier diode detectors have standard negative output polarity.

  • IR Detectors

    Opto Diode

    Opto Diode manufactures high performance infrared detectors with a wide variety of active area sizes, cooling alternatives, packaging, windows, lenses, and filters options. These detectors are ideal for gas analysis, emissions monitoring, spectroscopy, process control, flame and fire monitoring. Our A Series lead sulfide (PbS) detectors provide the highest sensitivity in the 1µm to 3µm wavelength region. Our B Series lead selenide (PbSe) detectors deliver the best overall performance in a wider spectral range from 1µm to 5µm. Our multichannel (MCDs) devices are ideal for simultaneous detection of multiple gases including CO2, CO, and other hydrocarbons.

  • Pyroelectric Detectors

    Laser Components IG, Inc.

    Pyroelectric detectors are thermal detectors; i.e. they create an electric signal due to temperature changes in the chip. This temperature change is caused by absorption of light. We do use LiTaO3 and DLaTGS as pyroelectric materials. Basically such detectors cover the whole spectra. However, they are mainly used for mid-wave and long-wave infrared detection (MWIR and LWIR). In addition, the usage in the THz region seems to become more popular these days.

  • RF detectors

    Fairview Microwave Inc.

    RF detectors from Fairview Microwave are available with N Type or SMA connector series inputs and BNC or SMA connectors for outputs. Fairview RF detectors are zero bias Schottky diode and have negative video out. These zero bias Schottky diode detectors for RF have a minimum frequency between 10 MHz and 2 GHz and maximum frequency range between 2 GHz and 26.5 GHz.

  • Event Detectors

    STD Series - Analysis Tech Inc.

    The STD Series Event Detectors offer test specifications associated with solder joint reliability testing but can also be used for testing other types of interconnects accordingly. Like other Event Detectors, the STD series provides continuous transient resistance detection referenced to a selected threshold resistance with a high degree of electrical noise immunity.

  • Radiation Detectors

    ORTEC

    High Purity Germanium (HPGe) DetectorsSilicon Charged Particle DetectorsScintillation DetectorsORTEC is a leading supplier of solid-state, high resolution, semiconductor radiation detectors. These radiation detectors are used in research, commercial industry, environmental protection, health and medical physics, as well as homeland security to detect gamma-rays, X-rays, and charged particles.

  • Special Detectors

    B.Hagner AB

    A Range of Special External Detectors for use with the Hagner Universal Photometers, the Hagner E4-X Digital Luxmeter or the Hagner MCA-1600 Multi-Channel Amplifier is available for various types of special measurements. Items currently available from the range are listed below but new detectors are being additionally developed.

  • Metal Detectors

    Moduloc

    Metal Detectors operate by generatinga pulsed flux and monitoring its rate of collapse when the metal bar passes overhead.

  • RF Detectors

    ZTS Technologies Co., Ltd

    ATJ8 coaxial detectors are used in kinds of military or civil electronic equipment,such as communication, radar, navigation microwave, measurement.

  • Event Detectors

    105/106 Series - Analysis Tech Inc.

    The 105/106 Series Event Detectors are the most versatile Event Detectors in the product line. These Event Detectors monitor the electrical resistance of up to 128 simple continuity loops, each comprised of single or multiple specimens under test. Each test specimen is continuously monitored while a selectable DC sense current is passed through each channel test-loop; resistance changes exceeding the selected threshold are recorded as an event. Minimum Event Duration, Channel Current, and Threshold Voltage settings can all be independently configured. 105 and 106 Series instruments are electrically identical, with the difference simply that the 105 offers four, 32-channel board slots and the 106 offers only one. Thus the 128-105 is equivalent to four 32-106 Event Detectors.
