  1. Measuring Refractive Index of Liquids Inside Sealed Containers

    Metricon’s Model 2010/M accurately and rapidly measures refractive index of liquids inside sealed containers such as glass vials/bottles, allowing rapid and non-destructive measurement of solution concentration for quality control purposes. Matching liquids are not required between the measuring prism and the wall of the container. If a label is present, the only requirement is that there be a gap of...
  2. A History of ZYGO Optical Profilers

    Some brief notes on the systems and technology over the years: Heterodyne profiler Maxim 5700: Micro Fizeau, tip/tilt in the head, PSI (Phase Shifting Interferometry), HPUX system controllers. Maxim 3D: PSI, 2 wavelengths for rougher surfaces, HPUX system controllers. NewView 100: The first Scanning White Light Interferometer (SWLI) from Zygo, uses Frequency Domain Analysis (FDA) to achieve high resolution over...
  3. Energy Storage Application Note – Water Splitting

    Among the solar fuel technologies, water splitting is a relatively mature technology that uses renewable electricity and water to product H₂. Storing renewable energy as H₂ is a solution for the intermittency problem of solar cells and wind turbines. Moreover, a large amount of H₂ is produced in non-renewable ways every day for important industrial processes. Replacing that H₂ by...
  4. Catalysis Application Note – CO₂ Hydrogenation

    CO₂ capturing and utilisation technologies have the potential of decreasing the CO₂ emissions that cause climate change. Utilisation of CO₂ also allows to directly recycle the CO₂ produced in the industry to make the process carbon neutral and to produce value-added products (fuels and chemicals). Methanol is an excellent product for CO₂ utilisation, since it is already produced world-wide in large...
  5. Catalysis Application Note - Fuel Cells Research

    Fuel cells Storing electricity into fuels is a promising way to solve the intermittency problem of solar cells and wind turbines. However, in order to start implementing renewable fuels, the conversion process from these fuels back to electricity needs to be carried out efficiently and cheaply. Fuel cells are devises that can convert a great variety of chemical fuels into...
  6. Catalysis Application Note - CO2 Electroreduction

    CO2 Electroreduction CO2 electroreduction is a promising technology that uses intermittent renewable electricity and CO2 emissions to product fuels (e.g. methanol) and other economically relevant products (e.g. syngas). One of the great promises of this technology is to recycle the CO2 produced by factories, reducing CO2 emissions and its impact to climate change. In order for CO2 electroreduction to play...
  7. AN-117 Measuring Insertion Loss and Return Loss of Hybrid Cables in OPL-MAX

    Obtaining connector-level insertion loss (IL) and return loss (RL) for hybrid cables is complicated by the different connector types on either end of the cable. Hybrid cables cannot simply be flipped to test the reverse direction when the reference and device under test (DUT) connectors are no longer compatible. A test setup comprised of the OP940 IL and RL Meter...
  8. How Can You Accurately Test Performance of Hybrid Cables?

    Fibre patch cables, also known as patch cord or jumper cables, are fibre optic cables that are terminated with connectors on both ends. When the connector types on each end are different, the cable is aptly dubbed a HYBRID CABLE. These hybrid cables can serve to link otherwise incompatible infrastructure in existing fibre systems, such as those found in networks...
  9. The 3D scanner in a unique design for creating an anatomical baby bottle

    Today, the accessory industry for newborns and infants is a dynamically developing business sector. Manufacturers compete to invent increasingly sophisticated and creative products designed to help young parents in caring for their children. Among the many colourful and often unnecessary products, there are exceptional products that are designed to really help and support parents to create normality where it’s not...
  10. Full area topography and thickness of sub-micron films

    Precise, reliable, characterisation of thin film topography and thickness, and substrate topography. Thin transparent thin films are critical across a variety of markets and applications, including consumer electronics, semiconductors and optics. Precise monitoring and control of thin film processes is achieved by measuring top surface, thickness, and substrate surface characteristics – all of which are enabled by multiple thin film measurement and...
