Capacity data enable spotting scopes to be compared with one another.

More information:

  • Exit pupil
    The diameter of the beam of light, which enters the eye through the eyepiece. The larger the exit pupil, the brighter the image.
  • Focusing system (1)
    System for the focusing of objects. Usually a focusing wheel or a rotating ring.
  • Front lens diameter
    Determines the light intensity or brightness of the image. The larger the front lens diameter, the better the spotting scope performs in low light conditions.
  • Glass material (2)
    There are different types of glass that offer certain advantages due to their specific characteristics.
  • Lens coating
    Optical surfaces are metallized with coatings to increase the optical performance of the instrument.
  • Magnification
    Specifies how much larger an object appears compared to when viewed with the naked eye. For most spotting scopes, variable magnification zoom eyepieces are available.
  • Type of build (1)
