Latus Rectum
::
Latus
rectum
() The line drawn
through
a focus of a conic
section
parallel
to the
directrix
and
terminated
both ways by the
curve.
It is the
parameter
of the
principal
axis. See
Focus,
and
Parameter..
Sunglow
::
Sunglass
(n.) A
convex
lens of glass for
producing
heat by
converging
the sun's rays into a
focus.
Focal
::
Focal (a.)
Belonging
to,or
concerning,
a
focus;
as, a focal
point..
Focimeter
::
Focimeter
(n.) An
assisting
instrument
for
focusing
an
object
in or
before
a
camera.
Concentrate
::
Concentrate
(v. t.) To bring to, or
direct
toward,
a
common
center;
to unite more
closely;
to
gather
into one body, mass, or
force;
to fix; as, to
concentrate
rays of light into a
focus;
to
concentrate
the
attention..
Aberration
::
Aberration
(n.) The
convergence
to
different
foci, by a lens or
mirror,
of rays of light
emanating
from one and the same
point,
or the
deviation
of such rays from a
single
focus;
called
spherical
aberration,
when due to the
spherical
form of the lens or
mirror,
such form
giving
different
foci for
central
and
marginal
rays; and
chromatic
aberration,
when due to
different
refrangibilities
of the
colored
rays of the
spectrum,
those of each color
having
a
distinct
focus..
Hyperbola
::
Hyperbola
(n.) A curve
formed
by a
section
of a cone, when the
cutting
plane makes a
greater
angle with the base than the side of the cone
makes.
It is a plane curve such that the
difference
of the
distances
from any point of it to two fixed
points,
called
foci, is equal to a given
distance.
See
Focus.
If the
cutting
plane be
produced
so as to cut the
opposite
cone,
another
curve will be
formed,
which is also an
hyperbola.
Both
curves
are
regarded
as
branches
of the same
hyperbola.
See
Illust.
o
Focalize
::
Focalize
(v. t.) To bring to a
focus;
to
focus;
to
concentrate.
Collimator
::
Collimator
(n.) A tube
having
a
convex
lens at one end and at the other a small
opening
or slit which is at the
principal
focus of the lens, used for
producing
a beam of
parallel
rays; also, a lens so
used..
Directrix
::
Directrix
(n.) A
straight
line so
situated
with
respect
to a conic
section
that the
distance
of any point of the curve from it has a
constant
ratio to the
distance
of the same point from the
focus.
Eccentricity
::
Eccentricity
(n.) The ratio of the
distance
between
the
center
and the focus of an
ellipse
or
hyperbola
to its
semi-transverse
axis.
Focalization
::
Focalization
(n.) The act of
focalizing
or
bringing
to a
focus,
or the state of being
focalized..
Focus
::
Focus (n.) A point in which the rays of light meet, after being
reflected
or
refrcted,
and at which the image is
formed;
as, the focus of a lens or
mirror..
Myopia
::
Myopia
(n.)
Nearsightedness;
shortsightedness;
a
condition
of the eye in which the rays from
distant
object
are
brought
to a focus
before
they reach the
retina,
and hence form an
indistinct
image;
while the rays from very near
objects
are
normally
converged
so as to
produce
a
distinct
image.
It is
corrected
by the use of a
concave
lens..
Focus
::
Focus (v. t.) To bring to a
focus;
to
focalize;
as, to focus a
camera..
Emmetropia
::
Emmetropia
(n.) That
refractive
condition
of the eye in which the rays of light are all
brought
accurately
and
without
undue
effort
to a focus upon the
retina;
--
opposed
to
hypermetropia,
myopia,
an
astigmatism..
Image
::
Image (n.) The
figure
or
picture
of any
object
formed
at the focus of a lens or
mirror,
by rays of light from the
several
points
of the
object
symmetrically
refracted
or
reflected
to
corresponding
points
in such
focus;
this may be
received
on a
screen,
a
photographic
plate,
or the
retina
of the eye, and
viewed
directly
by the eye, or with an
eyeglass,
as in the
telescope
and
microscope;
the
likeness
of an
object
formed
by
reflection;
as, to see one's image in a
mirror..
Focused
::
Focused
(imp. & p. p.) of Focu.
Reticule
::
Reticule
(n..) A
system
of wires or lines in the focus of a
telescope
or other
instrument;
a
reticle.
Polar
::
Polar (n.) The right line drawn
through
the two
points
of
contact
of the two
tangents
drawn from a given point to a given conic
section.
The given point is
called
the pole of the line. If the given point lies
within
the curve so that the two
tangents
become
imaginary,
there is still a real polar line which does not meet the
curve,
but which
possesses
other
properties
of the
polar.
Thus the focus and
directrix
are pole and
polar.
There are also poles and polar
curves
to
curves
of
higher
degree
