  • The Nanoworkbench

    Klocke Nanotechnik

    In light microscopy it is natural to use toolsets like tweezers, knives, probes and several different measurement tools. Without this many present-day products and methods would not exist. The operators of SEM/FIB-Systems generally work without toolsets, although the wavelength limit of light is no physical boundary. It can be imagined how technology would be pushed when a SEM/FIB Workbench reaches the same degree of practicability and utilization as toolsets for light microscopes. The Nanoworkbench is the first system substituting the eye-hand coordination effectively with nm precision in a SEM/FIB-system. The Nanoworkbench features a set of applications including TEM lamella preparation, nano probing, nano cutting, nano cleaning, force distance measurement, particle sorting and material preparation. Every application supports automated processes so almost no user interaction is needed. Even complex processes can be done within seconds and even by untrained users. Applications can be combined to create new and more complex processes. Expanding the SEM/FIB to a material processing system and a nano-analytical workbench by utilizing the Klocke Nanoworkbench enables new applications in research and production of material research, live sciences, tribology, environmental & forensic research and semiconductor technology.

  • 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


    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.

  • Lux Meters

    PCE Instruments

    Lux meters for measuring brightness in lux, fc or cd/m². Some lux meters are equiped with internal memory or a data logger to record the measurments. The measurment of light intensity with these lux meters is becoming increasingly important in th Lux meters for measuring brightness in lux, fc or cd/m²e workplace where protective screens are needed to avoid risk. Lux meters with data loggers as shown in our online store, are highly regarded especially due to their cosine correction of the angle of incident light. These lux meters have memory to store measured values, and moreover software in addition to different interfaces which make it possible to transfer measured data to a computer. On the computer, further analysis can take place. We also offer a meter for measuring UVA radiation.

  • 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.
