  • Scanning Electron Microscopy

    SEM - Materials Evaluation and Engineering

    JEOL JSM-6610 LV LaboratoryScanning electron  microscopy (SEM) uses electrons for imaging to obtain higher magnifications and greater depth of field than light microscopes. The instruments at MEE are capable of variable-pressure, or low vacuum, SEM (VPSEM), as well as traditional high-vacuum conditions for sample observation. VPSEM is a specialized method using a variable-pressure sample chamber that allows direct evaluation of samples that are not readily examined with a traditional high-vacuum SEM. Nonconductive or vacuum sensitive samples that would typically require additional sample preparation can be directly analyzed in VPSEM without the need for additional sample preparation, such as carbon or metallic conductive coatings. This reduces both sample preparation time and distractions in microanalysis. Our laboratory also has a field emission SEM (FESEM) for critical high-magnification work and low-voltage (LVSEM) applications. Each instrument has a spacious sample chamber that can accommodate large and irregularly-shaped specimens and accessories for feature dimensional analysis and chemical microanalysis.

  • Adjustable Clamshell Bed of Nails Testers

The AdjustaBON competes with the Flying Prober. There are many advantages over the flying prober. Setup is simple and intuitive and can be much quicker than programming a flying prober. Small size provides versatile bench top operation right where you need it. Maintenance costs are insignificant in comparison. The total cost of this fixture is in many cases less than the yearly maintenance cost of a flying prober. It would be possible to buy one of these fixtures every year for the price paid just to maintain one flying prober and it is about 1/20th the purchase price

  • Surveyor Thickness Gauge

    Multigauge 5650 - Tritex

    The Multigauge 5650 Surveyor Thickness Gauge is a simple, robust ultrasonic thickness gauge designed specifically for ship and small craft surveyors, but can also be used in applications where different measurement modes are required.

The gauge can be used for metal, GRP or plastic measurement and it automatically switches modes and settings depending on the type of probe fitted. The easy to use keypad on the Surveyor Thickness Gauge allows operator interface whilst the bright LCD display can be used in all light conditions. All probes have Intelligent Probe Recognition (IPR), which automatically adjusts settings in the gauge at the same time as transmitting recognition data the result is a perfectly matched probe and gauge for enhanced performance. Additionally, the Automatic Measurement Verification System (AMVS) used with multiple echo ensures only true measurements are displayed, even on the most heavily corroded metals.

  • 6000 Series Digital I/O Modules

    Pacific Instruments, Inc.

    Series 6000 digital I/O modules record signals from frequency counters, flow meters, encoders, discrete transducers, IRIG time, etc. which are often part of the test environment. These digital signals are time aligned and recorded alongside the system’s analog measurements. High density digital inputs provide an opportunity to easily include facility controls like switches, valve positions, relays, lights, etc. along with the test data. Series 6000 digital I/O modules also provide outputs generated by user command or automatically by Sequence, Alarms or DSP. User generated outputs are accomplished in software while sequencers can be programmed prior to a test and initiated by program or hardware control. Alarm conditions preprogrammed on the analog side can automatically generate digital outputs which are typically connected to facility control systems or PLCs. A DSP adds powerful real-time processing and is appropriate for PID control loops, derived parameter calculations and a variety of other real-time operations.

  • Fourier Transform Optical Spectrum Analyzer, 600 - 1700 nm

    OSA202C - Thorlabs, Inc.

    Thorlabs' Optical Spectrum Analyzers (OSAs) perform highly accurate spectral measurements. Compatible with fiber-coupled and free-space light sources, these compact benchtop instruments suit a wide variety of applications, such as analyzing the spectrum of a telecom signal, resolving the Fabry-Perot modes of a gain chip, and identifying gas absorption lines. Many commonly available OSAs use grating-based monochromators, which have slow acquisition times due to the need to mechanically scan the grating and average out noise at each wavelength. Thorlabs' OSAs acquire the spectrum via a Fourier transform using a scanning Michelson interferometer in a push/pull configuration. This approach dramatically improves the acquisition time, enables a high-precision wavelength meter mode with 7 significant figures and ±1 part-per-million accuracy, and allows the included software to provide robust statistical analysis of the acquired spectra, as explained in the Design tab.

  • 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).
