  • Uniform Light Sources

    SphereOptics GmbH

    An internally illuminated integrating sphere provides spatially uniform luminance and illuminance which is perfect for flat-field correcting and calibrating imaging systems, calibrating photometers and spectroradiometers and for testing detector arrays and remote sensing instruments. Integrating sphere-based sources, also known as uniform light sources, exhibit luminance uniformity at the 98-99% level over the full exit port area, which is significantly higher than can be achieved using alternative techniques.Labsphere´s uniform light sources are coated with high reflective Spectraflect coating. A number of different optical accessories like optical attenuators, filter wheels, different types of detectors and the option of Spectralon coating allow an easy adaption of standard uniform light sources to almost any application. All light sources are controlled by a user friendly software interface.

  • Terahertz Source

    Optilab, LLC.

    Optilab’s Terahertz Source is a set of fully integrated optical heterodyne signal sources packaged in a 1u rack mount configuration. Based on Tunable Wavelength Laser (TWL) systems, the Optical Heterodyne Source series produce optical heterodyne signals up to 10 Terahertz. An optical heterodyne is a signal produced by the frequency beat of two optical sources. The beating makes the optical signals detectable by GHz and slower, square-law detectors such as PDs and finds varied uses in LIDAR, spectroscopy and other high phase-sensitivity applications. The Optical Heterodyne Source series provides high accuracy and high stability optical heterodyne signals over large signal range. The integrated GUI software gives the user full control of the optical heterodyne signal.

The same wide range of slits, gratings and other options available in the mainline spectroscopy lineup are also available for the ULSi.

  • Spectrometer

    Model 207 - McPherson, Inc.

    The Model 207 offers the user the most throughput and fastest aperture in a long focal length monochromator. This is ideal for photoluminescence and Raman spectroscopy applications. It is also available in a vacuum compatible version. Used in air and with a selection of gratings, the spectral range of the 207 extends from 185 nanometersm to 20 microns or more. Under vacuum range is extended down to 105 nm (depends on the grating.) Multiple ports are available for mounting accessories or CCD detectors, etc. McPherson SNAP IN gratings allow the alignment-free use of many different gratings. Easily view a wider spectral range or obtain higher resolution! You can retrofit years later and not have to worry about alignment with the McPherson SNAP IN approach. Our dual grating turret also accepts these easy to exchange gratings.

  • Full Band Scalar Network Analyzer Extenders

    Sage Millimeter, Inc.

    Full band scalar network analyzer extenders are designed to extend low frequency scalar network analyzers to higher millimeterwave frequency ranges. These extenders offer a low cost means of producing millimeterwave scalar network analyzers while preserving the functionality and features that industry standard models offer. These extenders deliver a superior performance since they are assembled with SAGE Millimeter’s instrumentation grade frequency extenders (STE series), Faraday isolators (STF series), direct or programmable attenuators (STA series), directional couplers (SWD series) and waveguide detectors (STD series). The below standard offering covers the frequency range of 26.5 to 170 GHz. Specifications other than those listed below are available upon request.

  • Antenna Analyzer

    AIM-4300 - Array Solutions

    It measures the complex impedance (magnitude and phase) at each frequency of interest in the range of 5 kHz to 300 MHz. A PC is used to calculate all RF parameters, including R +/-jX, Magnitude and Phase, SWR, Return Loss, TL loss, and more and plot the results in an easy to read graph and interactive Smith Chart.The test frequency is generated digitally and bandpass filters are used to reject stray signals (like broadcast stations) that are more than a few KHz from the operating frequency. A 12 bit analog to digital converter digitizes the raw data. This avoids non-linearities associated with diode detectors, and results in very good dynamic range and linearity for accurate magnitude and phase measurements.
