  • TMD37003 cRGB Color and Proximity Sensor

    SEN-36004 - Playing With Fusion Inc

    Fully integrated carrier board designed to get the most out of the TMD37003 cRGB (color with IR compensation) and Proximity Sensor from AMS. This means that the board includes a 1.8V-5V input range LDO and high-speed signal voltage translation on all IO pins. In addition, we've added a high output white LED that is tuned to the light temperature range of the TMD37003 IC. This makes sensing color of close-proximity objects possible, such as in robotic color sorting operations. As on many of our boards, we've included 4-40 sized mounting holes to make installation easy. The IC functions are interfaced via a 0.1" header, which includes power (Vdd and GND), I2C interface (again, fully translated) and a 3.3V input to power the proximity (IR) LED. The on-board LED is turned on with a logic 'HIGH' applied to the LED pin and is powered with Vdd.

  • Tome & Probe Kit

    Daerim Electronics Co.

    Without direct metallic contact, this kit can quickly and accurately trace and identify the specific wires within a bundle, at a cross-connect point or remote end. It works with all types of wire and cable, including twisted pair, multiconductor cable, de-energized AC wire, speaker wire, coaxial, security & alarm cable and LAN cable. TRACER-A(DR-77A) is a tone generator, which applies its tone signal to a wire pair that the user want to identify at the far end or within a bundle. For the easy access to wires, it has test lead wires with ABN clips and modular plug(RJ-11). Belt clip is convenient for the easy carry. Independently it can work to test polarity and continuity. TRACER-B(DR-77B) identifies the specific pair through the bell sound and LED light. Its recessed on/off control button prevents the accidental push. TRACER-A & B can be purchased separately.

  • Cassegrain Antennas

    Sage Millimeter, Inc.

    Cassegrain antennas are offered with a 6”, 12”, 18”, 24”, 36” and 48” diameter main reflector dish. These antennas are designed and manufactured with the highest performance and quality. The main advantages of the Cassegrain antenna are its low loss, low profile and light weight compared to other high gain antennas, such as prime focus and lens corrected antennas. As a downside, this antenna has relatively high side lobe levels compared to other antennas due to the interference of the sub-reflector’s supporting structure. To ensure good performance, the supporting structures are specially designed to keep side lobe levels under 18 dB for narrow band operations and under 16 dB for broadband operation. The standard offering covers the frequency range of 18 to 110 GHz, but custom frequencies can be requested. The operating bandwidth of these antennas is mainly limited by the circular waveguide’s dominant mode operation. While standard models are equipped with a circular waveguide interface, a rectangular waveguide interface is also available.

Saint Gobain’s manufacturing process ensures high light output as well as excellent pixel to pixel uniformity with minimal crosstalk.  Linear arrays are used quite often in security type applications (airport baggage scanners) whereas 2D arrays are used more in medical imaging applications.  Both types are also found in non-destructive testing / inspection machines.  The type of material depends on the application, and the information being sought.

  • SWIR Microscopes with SWIR InGaAs Cameras

    Pembroke Instruments

    Our SWIR microscope cameras are designed to deliver superb image quality in real world conditions where intrascene dynamic range is quite high. This is accomplished through proprietary Wide Dynamic Range ROIC technologies and offer a Dynamic Range (DR) of more than 140dB in a single image without any external control. Other InGaAs cameras will suffer pixel saturation and deliver very poor image quality when the scene conditions demand high dynamic range from the camera. The internal Fixed Pattern Noise correction gives a high uniformity pictures in all light conditions with no need of Look-up table. The WDR InGaAs sensors use InGaAs photodiodes array operating from 900nm up to 1700nm with a high QE and coupled to a patented Read Out Circuit (ROIC).
