[Fluorite]
In theory, chromatic aberration cannot be completely
eliminated in standard optical glass, and a slight
chromatic aberration always remains. A material
called fluorite (CaF2) can be used to resolve this
problem in optical glass and enables ideal chromatic
aberration correction. Fluorite has been known to
have an anomalous dispersion characteristic (which
optical glasses do not have), which is effective in
eliminating chromatic aberration. Fluorite lenses have
been used in a number of Canon lenses and
effectively correct the chromatic aberration.
Spherical lens refracts more in the periphery portions than in the center.
For that reason, it is impossible to collect a beam of light at the optimal
one point. This is called spherical aberration, and this aberration can be
corrected by combining multiple lenses. On the other hands, the
aspherical lens can collect the light that passes through both the center
portion of the lens and the periphery portion of the lens at one point. The
performance obtained by using several spherical lenses can be achieved
using a single aspheric lens. Therefore, the number of lenses in the entire
lens configuration can be reduced. This technology contributes to a
reduction in the size and weight of the lenses and at the same time
makes it possible to produce sharp images owing to its outstanding
optical performance. Canon produces high-performance aspherical lenses
by means of advanced manufacturing technologies such as aspherical
surface grinding and glass molding processes.
The CN7x17 KAS S has adopted the inner-focus-type lens formed by a three-lens group, which is a highly proven configuration for
broadcast and cinema applications. The lens reduces changes in angle of view that are caused by focusing.
[UD and Hi-UD glasses]
The development of glass materials with an anomalous dispersion
characteristic similar to fluorite has been progressing recently. These efforts
have produced Ultra-low Dispersion (UD) glass. Since UD glass has low
dispersion as well as an anomalous dispersion characteristic, effects similar
to those of fluorite can be achieved by selecting the proper combination.
Furthermore, Hi-UD glass offers high refraction in addition to low and
anomalous dispersion characteristics of UD glass, which enables spherical
aberration correction as well as chromatic aberration. Hi-UD glass is used
for Canon lenses and effectively functions to reduce aberration fluctuation
caused by focusing and zooming, in addition to the chromatic aberration
that occurs on the telephoto side.
