  2. Optical manufacturing and testing - Wikipedia

    en.wikipedia.org/wiki/Optical_manufacturing_and...

    Optical manufacturing and testing is the process of manufacturing and testing optical components. It spans a wide range of manufacturing procedures and optical test configurations. The manufacture of a conventional spherical lens typically begins with the generation of the optic's rough shape by grinding a glass blank. [1]

  3. Surface metrology - Wikipedia

    en.wikipedia.org/wiki/Surface_metrology

    Surface metrology is the measurement of small-scale features on surfaces, and is a branch of metrology.Surface primary form, surface fractality, and surface finish (including surface roughness) are the parameters most commonly associated with the field.

  4. Equipment rental - Wikipedia

    en.wikipedia.org/wiki/Equipment_rental

    Equipment rental was first developed in Anglo-Saxon countries. It emerged in the UK after the First World War and has now become a multi-billion euro business providing a wide range of construction and industrial equipment for customers globally.The American Rental Association was founded as early as 1955, [1] and the first waves of consolidation took place in the 1970s in North America ...

  5. Optical time-domain reflectometer - Wikipedia

    en.wikipedia.org/wiki/Optical_time-domain...

    It is the optical equivalent of an electronic time domain reflectometer which measures the impedance of the cable or transmission line under test. An OTDR injects a series of optical pulses into the fiber under test and extracts, from the same end of the fiber, light that is scattered (Rayleigh backscatter) or reflected back from points along ...

  6. Maskless lithography - Wikipedia

    en.wikipedia.org/wiki/Maskless_lithography

    Direct laser writing is a very popular form of optical maskless lithography, which offers flexibility, ease of use, and cost effectiveness in R&D processing (small batch production). The underlying technology uses spatial light modulating (SLM) micro-arrays based on glass to block laser pathway from reaching a substrate with a photoresist (in ...

  7. Tensiometer (surface tension) - Wikipedia

    en.wikipedia.org/wiki/Tensiometer_(surface_tension)

    In surface science, a tensiometer is a measuring instrument used to measure the surface tension (γ) of liquids or surfaces.Tensiometers are used in research and development laboratories to determine the surface tension of liquids like coatings, lacquers or adhesives.

  8. Optical cage system - Wikipedia

    en.wikipedia.org/wiki/Optical_cage_system

    An optical cage system is an optomechanical system that is used to mount optical elements such as lenses and mirrors together in a rigid assembly. Optical systems built this way can be more compact than can be achieved using an optical table , and the system provides more flexibility than an optical rail .

  9. Starfire Optical Range - Wikipedia

    en.wikipedia.org/wiki/Starfire_Optical_Range

    The range is a secure lab facility and is a division of the Directed Energy Directorate of the Air Force Research Laboratory. SOR's optical equipment includes a 3.5 meter telescope which is "one of the largest telescopes in the world equipped with adaptive optics designed for satellite tracking" according to the Air Force, a 1.5 meter telescope ...
