  • Observing and Measuring Visual Double Stars
    The classic image of the double-star observer as a professional scientist with a large refractor and a brass filar micrometer is no longer valid.

    15 The Filar Micrometer . . . . . . . . . . . . . . . . . . . .
  • Double and Multiple Stars and How to Observe Them
    All observatory telescopes were supplied with filar micrometers for measuring binary stars,for then as now they provided our only direct means of determining stellar masses.
  • Biographical Encyclopedia of Astronomers
    Adrien Auzout is known primarily for his work in astronomy, mathematics, and physics, with his main contribution to astronomy being his efforts in the development of the filar micrometer and telescopic sights.
  • Handbook of Practical Astronomy
    Other observational tools include color and polarization filters and also, for instruments with ?-in. or larger apertures and clock drive, filar micrometer .
    In the course of perfecting a new type of x-y filar micrometer , we have come upon a form of construction for precision mechanisms that is adaptable in a wide range of applications.
  • Celestial Shadows
    In the era before the filar micrometer was teamed with giant refractors, the eclipse-timing method proved the most practical method for estimating the diame- ters of the satellites.
  • Uveal melanoma
    For comparison, a related visually measured nucleolar feature (MLN) was obtained from hematoxylin and eosin stained sections using a filar micrometer .
  • ZMALT1983pg075
    The changes in length on heating between equilibrium temperatures were measured with filar micrometer eyepieces.
  • Precise Measurement Of Fibre Geometry By Image Shearing
    With the microscope focused on .a cleaved end face of the fibre, a movable hairline in the eyepiece (termed a filar micrometer eyepiece) is positioned to lie in turn tangentially to the various fibre boundaries and readings are taken at each setting �
