All telescopes use curved lenses to focus the light
from distant objects, such as stars. Generally, the
larger a telescope is, the greater its magnifying power.
Two different kinds of lenses can be used. Some
( 5 ) telescopes use a transparent lens that focuses light rays
as they pass through it. These telescopes are called
refractors. Other telescopes, called reflectors, use a
curved mirror shaped like a dish. The mirror focuses
light on a viewing lens placed between the opening of
( 10 )the telescope and the mirror. Because the viewing lens
is small, it does not interfere with the image.
The first telescopes, made during the sixteenth
century, were refractors. Their perfectly round lenses,
however, did not focus light sharply. Lenses made of a
( 15 )single piece of glass also bent light of different colors
differently, producing color distortions. Opticians
eventually overcame these problems by changing the
curvature of the lens and constructing lenses out of
layers of different kinds of glass.
( 20 )Meanwhile, the problems of refractors led some
telescope makers to experiment with reflectors. They
used mirrors that were not perfectly round, so that
light was sharply focused. Moreover, mirrors did not
produce color distortions. But these early reflectors
