New ideas for even better visibility
Leica represents
innovation. Our own outstanding achievements in terms of lenses
and mechanics are being continuously monitored and the standards
set even higher. Which is why Leica binoculars and spotting scopes
Fluoride lenses
With the help of new
fluoride (FL) glass, in Leica HD and APO
models the color fidelity and contrast
of images is further improved. Optical
FL lenses are to a large part made up
of calcium fluoride, a mineral with a
crystalline structure. Unlike convention-
al optical lenses, this creates a very
low level of dispersion (light scattering)
and corrects aberration (imaging errors)
significantly better. So as a result, the
viewing experience is more natural and
impressive than it has ever been before.
Without fluoride lenses, troublesome color
fringing can occur, and so contrast and
sharpness appear weakened.

optical Leica FL lenses reduce color effects
to a minimum – and so nature is rendered
clearly and without distortion.
Consistently smooth focusing – whatever the temperature
The mechanics
for the Ultravid HD focusing have been further refined. As a result, focusing is even
smoother and remains free of play across the entire range. Optimized material pair-
ings and gliding discs made from extremely tough, high-performance plastic are
used. In cold conditions, the conventional greased focusing mechanisms sometimes
only work with difficulty, and at higher temperatures they
move too freely. Furthermore, these focusing mechan-
isms can feel “sticky”, and at higher temperatures there
is even the danger that grease can escape and run on
the lens. With the optimized Leica focus, these risks
have been eliminated. In the new Ultravid-HD
models, it works practically without any
lubricants. So even in extreme
temperatures, it is always fully
functional – with a
constantly optimum
degree of smooth-
ness.
Excellent image quality – even in
awkward light conditions
Stray or
false light can significantly reduce the
viewing experience. To eliminate this
effectively, Leica is taking a great num-
ber of steps which, in awkward side-
lighting and backlighting situations in
particular, ensure a high-resolution,
clear image without any reduction in
contrast or constraints due to milky
fogging. Specially developed software
simulation allows stray light to be seen
during development stage. Consequent-
ly, thanks to an optimized housing
shape, improved light-absorbing paint,
apertures and stray light traps, the
construction of the new HD and APO
models have been optimized to such
a degree that stray light is (almost) no
longer of any significance. Because
after all, you cannot select the position
of the sun when you are observing
nature.
