  • Spectroscopic Reflectometer

    SR Series - Angstrom Sun Technologies, Inc.

    Spectroscopic reflectometer (SR) series are relative low cost and easy to use tools. To enusre accurate measurement on spectra, a long working distance and also adjustable working distance set up are professionaly desgined and considered. Since reflection spectra measurments require to use known reference to calibrate light intensity, it is hard to image user could get accurate spectra without optimizing signal step during such calibration because reference thickness is different from sample substrate's thickness in most of cases. Adjusting power output to lamp is our another consideration in ensuring a good measurement by reducing non-linearity effect of the detector

  • Polarimeters

    PCE Instruments

    The polarimeters of PCE are measurement devices in the field of photoelasticity to determine the mechanical stress in transparent solid bodies.

  • Deep Ultraviolet Spectrophotometer System

    VUVAS-10X - McPherson, Inc.

    A new ultraviolet spectrophotometer system for optical metrology just arrived at NASA Goddard! The VUVAS-10X spectrophotometer works best in the 90 to 160 nanometer wavelength range, also known as deep or vacuum ultraviolet (VUV) region. It uses a windowless hydrogen plasma light source and differential pump section to reach many wavelengths beyond those of conventional deuterium lamps. The source also works with other gases, or gas mixtures, for atomic spectral line emission from about 30 nanometers (double ionized Helium gas) up to the Visible light range. The new spectrophotometer system, McPherson VUVAS-10X, uses a one-meter focal length high-resolution monochromator with the special light source, scintillated detector and Model 121 goniometric sample chamber. The system is ideal for optical transmission, absorbance and specular reflectance at incident angles up to 60 degrees. This McPherson spectrophotometer system will help develop, inspect and qualify optical materials and coatings used for very high altitude and extraterrestrial space flight missions.

  • UV Cameras

    Inframet

    Solar blind UV cameras are imaging devices optimized to detect ultraviolet light of wavelengths below about 280nm. Such cameras are insensitive against sunlight due to negligible sensitivity to visible and long wavelength UV light. Solar blind UV cameras are used in a series of applications like corona detection, fire detection, combustion analysis, plasma research, testing UV lamps, etc. However, highly sensitive corona detection is the main mass application and these devices are of crucial importance in electric power industry. These imaging devices enable easy detection of degraded insulators of high voltage transmission lines, distributions and substations. They can see the emission of UV light when discharges occur at defect insulators. From design point of view solar blind UV cameras are actually bispectral imaging systems built by combining true UV camera with typical visible camera. These bispectral imaging system generate output image as overlay of typical visible image with UV image of analyzed UV source.

  • Mid-Range Gas Filter Correlation CO2 Analyzer

    Model T360M - Teledyne Advanced Pollution Instrumentation

    The Model T360M CO2 analyzer measures Carbon Dioxide by comparing infrared energy absorbed by a sample to that absorbed by a reference gas according to the Beer-Lambert law. Using a Gas Filter Correlation Wheel, a high-energy IR light source is alternately passed through a CO2 filled chamber and a chamber with no CO2 present. The light path then travels through the sample cell, which has a folded path of 1.28 meters.The energy loss through the sample cell is compared with the reference signal provided by the filter wheel to produce a signal proportional to concentration, with little effect from interfering gases within the sample. This design produces excellent zero and span stability and high signal to noise ratio, allowing excellent performance over a wide concentration range, making this instrument an ideal choice for CO2 reporting requirements associated with dilution CEMS.
