Finding the Most Effective Telescope Eyepiece
Review Online
Though it is impossible to correct all known aberrations in
man-made lenses, they can be effectively masked by the combination
of several precision lenses. These may be cemented together
with Canada balsam, a resin from the North American balsam fir
tree. Some lenses are coated to prevent “ghosting”
or reflections from forming. Complex systems are also employed
in telescopes, binoculars and microscopes. These apply the principle
of a convex objective lens for casting an image in the microscope
or telescope tube, which is not shown on any screen but is made
to fall within the focal length of an eyepiece. The image formed
there is then viewed through the eyepiece, giving a magnified
view of the object.
The inverted narrate of the image does not really matter in
the microscope. (The slide being viewed can be turned upside
down first.) But no ship’s captain would be happy with
his binoculars or telescope if his next port of call appeared
inverted. For this reason a correcting set of lenses or prisms
is introduced between the objective lens and the eyepiece to
rectify that problem. Lens making by intelligent men involves
a thorough knowledge of optics, refraction-of-light mathematical
formulas and then patient skill, learned and accumulated over
many years of training by another skilled in these arts.
