  • Radiometic and Photometric Concepts Based on Measuremet Techniques (.pdf)
    Application Note No. 6. April 1982. Radiometric and Photometric Concepts Based on. Measurement Techniques. C. Richard Duda. Senior Scientist, United Detector Technology. 3939 Lanmark Street, Culver City, Cal. 90230. Abstract. The value of the fundamental quality in radiometry, the bution of optical radiation
  • Water Processing: Control Cost and Improve Efficiency With Real-Time Monitoring
    optek photometric analyzers help to control cost and improve efficiency in any type of water processing. Real time monitoring improves processes and quickly alerts operators to non-compliant conditions. Industrial Water Treatment Processing Applications by optek. English | Deutsch | Español. Home
  • Modeling Phototransistor Optocouplers Using PSPICE Simulation Software
    While designed for measurement parameters like Voltage and Current, PSPICE programs are not comfortable with evaluating or simulating components in photometric units. This application note provides guidelines for using PSPICE to model phototransistor optocouplers
  • Chromatographic Separation
    optek UV sensors can be optimized for both high OD and low end resolution for monitoring real time protein concentration. optek AF45 or AF46 sensors have proven time and again to provide accurate measurements, better repeatability, and linear response. Inline photometric analysis can save time
  • Malema M-VF Series Adjustable Velocity Fuse
    Ionization (FID) and Flame Photometric (FPD) detectors. Spark discharge analyzers, total hydrocarbons measurements also use hydrogen mixtures. Using hydrogen as a carrier gas speeds up the process of analyzing the component. Microsoft Word - Application note-VF _5_.doc. 5/11/2005. Application note
  • Massive Black Holes Dwell in Most Galaxies, According to Hubble Census
    on a census of 27 nearby galaxies carried out by NASA's Hubble Space Telescope and ground-based telescopes in Hawaii, which are being used to conduct a spectroscopic and photometric survey of galaxies to find black holes which have consumed the mass of millions of Sun-like stars. The findings, being
  • Water in Acetic Acid On-Line Monitoring with a ClearViewTM Photometer
    . Results: The resulting spectra are shown at the top right. Minimum temperature sensitivity is found at 1420 nm. (vertical line). Excellent linearity is achieved (shown middle right) in the range tested, up to 15% water. The photometric drift (~2-4 weeks) of ClearViewTM is 1 mAU (0.001 Absorbance Units
  • Cold Cathode Fluorescent Lamps (CCFLs)
    . For an understanding of 3.0mm diameter CCFLs, which are increasingly found in LCD display modules, and to aid in the selection of a lamp diameter for a particular application, a comparison of photometric, electrical, and temperature characteristics are given for a 3.0mm and a 6.5mm lamp.
