  • Binoculars-Image
    Binoculars - (72 companies)
    Prismatic binoculars are constructed with eyepiece lenses, objective lenses, and a series of prisms to shorten the optical path. A small wheel mounted in the center between the two tubes focuses the image. Another adjustment usually in one...

    Gradient Index Lenses - (12 companies)
    Gradient index (GRIN) lenses focus light through a precisely controlled radial variation of the lens material's index of refraction from the optical axis to the edge of the lens. How to Select Gradient Index Lenses. Image credit: Thorlabs | Grintech...

  • The Urban Astronomer’s Guide
    An achromatic refractor, i.e., a telescope with a two-element objective made of crown and flint glass, the most pop- ular design of refractor objective lens for the last couple of centuries, cannot bring all colors of light to focus at …
  • On-sky observations with an achromatic hybrid phase knife coronagraph in the visible
    The refractor objective lens is an achromatic doublet opti- mized for the 560 nm wavelength.
  • PISCO2: the new speckle camera of the Nice 76-cm refractor
    The on-sky pixel scale of the whole instrument (telescope and PISCO2) can be calibrated in an absolute manner with a grating mask placed in front of the refractor objective lens .
  • Binocular Astronomy
    It is normally considered to consist of the tube itself, the focuser and the optical train from the objective lens ( refrac- tor ), primary mirror (reflector), or corrector plate (catadioptrics) up to, but not including, the eyepiece.

  • Reflecting Telescope Optics I
    As was so often the case in the fascinating history of the development of the telescope, the advance of the reflector to surpass the single lens objective refractor (above all because of compactness) was accompanied by a major breakthrough in the refractor.
  • Comparative analysis of the lidar receiving objectives
    Lens objectives ( refractors ) A lens with the spherical faces is the most simple objective for the single wave lidar.
  • Blazing a Ghostly Trail
    Therefore, a Newtonian of a certain aperture has less of a light- gathering surface than a refractor with an objective lens of equivalent diameter.
  • Mars and How to Observe It
    Refractors have an objective lens and an eyepiece at either end of a closed tube.
  • The Moon and How to Observe It
    Refractors have an objective lens and an eyepiece at either end of a closed tube.
