PIN Diodes
-
The SemiGen SGP7000 series of PIN Diodes are processed with a high-resistivity epi that have intrinsic layers that range in thickness from 4 micron to 200 micron depending on performance specifications. These devices are typically manufactured with either a robust thermal-oxide passivation or ceramic glass for durable high-power applications. These diodes are made with a grown junction P++ layer that yields abrupt junction structures that provide low punch through voltages and minimize autodoping. They are available as chips or in your choice of packages.

Current Pulsers and Laser Diode Drivers (Pulsed Current)
-
These instruments generate current pulses whose amplitude is largely independent of the load voltage. This makes them ideal for pulsing device whose voltage may vary with time (for instance, the voltage drop of laser diodes may vary with temperature, or explosive squibs which change impedance during ignition). This voltage independence is a trade-off with speed. If faster rise times are required, consider using pulsed voltage instruments instead.

Contactless Laser Extensometers
-
Jinan Testing Equipment IE Corporation
Model LE-05 and LE-15 extensometers measure strain optically, without contacting the specimen, using laser diode technology. The extensometers are self-contained and portable. They may be interfaced with a variety of testing machines and data acquisition systems using the ±10V analog output or bi-directional RS-232 serial port. Operation may be local or remote. A digital display is included. The scanning beam is always perpendicular to the specimen, unlike most laser extensometers. This eliminates errors when viewing through windows in chambers. It also minimizes sensitivity to the distance between the extensometer and the sample. Because the unit measures reflected light, no receiver is required behind the sample.

Deep Submersible Particle Size Analyzer
LISST-Deep
-
The LISST-DEEP instrument obtains in-situmeasurements of particle size distribution,optical transmission, and the opticalvolume scattering function (VSF). Using ared 670nm diode laser and a customsilicon detector, small-angle scatteringfrom suspended particles is sensed at 32specific log-spaced angle ranges. Thismeasurement is post-processed to obtainsediment size distribution, volumeconcentration, optical transmission, andVSF. The electronics and opticalconfiguration in the LISST-DEEP are verysimilar to Sequoia’s workhorse, the LISST-100X. However, because of the extremedifficulty associated with keepingalignment under high pressure, the LISSTDEEPhardware design is radically differentfrom the LISST-100X. This allows theLISST-DEEP to be deployed down to 3000m and obtain reliable measurements ofthe in situ particle size distribution andvolume concentration in waters withoptical transmission up to 98.5%.

MT
-
The MT cooler has been in production since 2003 and is based on the CT cooler design. It was developed for the customer who did not need the lift of the CT cryocooler and wanted size and weight reduction for their application. The MT has been used successfully in applications such as High Temperature Superconductivity (HTS) filters, high altitude balloons, refrigeration, germanium detectors, IR detectors, radio telescopes, laser diode cooling, and research among others. We believe the customer will agree that the CryoTel® MT is the smallest 5W @77K cooler available at an attractive price point with a Mean Time to Failure of over 200,000 hours.

Materials Development Corporation
A comprehensive set of analyses for junction diode or Schottky barriers begins with C-V data gathering that adjusts the voltage step to the slope of the C-V characteristics. This assures an optimum set of C-Vdata whether the voltage range is small or large. Doping profile and resistivity profile are both available at the touch of a key. Plots of 1/C2 - V or Log(C) - Log (V+ phi) show doping uniformity and doping slope factor. Exclusive recalculation options allow adjustment of stray capacitance and area to facilitate calibration using a standard reference wafer of known doping or resistivity.

Volume production oscillators utilize either high performance GaAs Gunn diodes with high Q cavity designs or state-of-the-art FET devices with dielectric resonators to yield excellent phase noise and stability. These oscillators are free running with extremely high frequency and power stability. The oscillators are generally designed and manufactured for fixed frequency applications. However, fine frequency adjustments can be achieved by mechanically tuning the provided self-locking screw. While the below standard models are offered for immediate production release, custom models are also available.
