单词 Galilean telescope
释义

Definition of Galilean telescope in English:

Galilean telescope

noun
  • An astronomical telescope of the earliest type, with a biconvex objective and biconcave eyepiece.

    Example sentencesExamples
    • A 3x afocal Galilean telescope has a separation between the objective and ocular lens of 2cm.
    • The Keplerian telescopic system is heavier than the Galilean telescope because the eyepiece and objective are composed of two plus lenses.
    • The reverse Galilean telescopes are tilted relative to each other.
    • Equations have been derived for Galilean telescopes and telemicroscopes that make it unnecessary to find pupils and ports, or to know the powers of the lenses.
    • Actually, the Galilean telescope was quickly abandoned for other types, in particular the design suggested by Johannes Kepler.
    • For instance, consider a Galilean telescope with a + 2.00 objective and a - 8.00 ocular.
    • Examples of refracting afocal systems include an ordinary Keplerian telescope, a Galilean telescope, and a lens-erecting telescope.
    • In 1611 Johannes Kepler invented the ‘astronomical telescope’, which had a much larger field of view than the Galilean telescope and a much brighter, although inverted, image.
    • When in alignment, the Galilean telescopes provide an increase or decrease in magnification, depending on orientation of the telescopes.
    • I actually have two on that replica Galilean telescope, so I made certain both were covered.
    • While the pupil of the Keplerian telescope can be matched to the observer's eye, the pupil of the Galilean telescope is always mismatched.
    • The main obstacles to the acceptance of these devices are cosmetic considerations, the ring scotoma caused by the magnification, and the limited field of the smaller Galilean telescopes.
    • A typical Galilean telescope with which Jupiter's moons could be observed was configured as follows.
    • The Astronomy Group built Galilean telescopes and used them to study the same heavenly bodies that Galileo did 375 years ago.
    • Eschenbach Galilean telescopes for distance are available in monocular or binocular systems.
    • The Galilean telescopes in the IMSS have rather strong ocular lenses, and unfortunately such lenses were not available from the department.
    • A variation on the Galilean telescope was suggested by Johannes Kepler in his 1611 book Dioptrice.
    • Reading systems can be fabricated which combine a Galilean telescope with a plus lens cap to focus at near.
    • The film does rather off-handedly allude to the fact that scientific innovations were important for the art of that time, particularly the camera obscura and the Galilean telescope.
    • During this activity we will concentrate on Keplerian and Galilean telescopes; telescopes made with two lenses instead of a combination of lenses and mirrors.
