(where q wave length, qo – preselected wave length);
antireflection band if qo=590 nm
420760;
spectral position wavelength
of the antireflection band center qc, nm

Innovative Aspect and Main Advantages
Achromatic antireflective coating could be used in optical and
quantum electronics with preset spectral characteristics. Due
to the new technology of their preparation the cost of these
devices is lower and the quality is comparable with the best
world analogous.

Stage of Development
Areas of Application
Achromatic antireflective coating intended for increasing the
efficiency and economy of optical and laser devices operation
by decreasing the losses value of light reflection from surfaces
of the optical elements with different value of refractive
indices, including the standard dispersion law in the range:
2.772.55 (silicon carbide), 2.442.2 (paratellurite, lithium
niobide, bariumsodium niobide etc.), 1.81.45 (glasses,
fused silica).
They are also used for reducing the glare and ghost images
from secondary reflections which will result in a clearer and
sharper image on any optical substrate, that are necessary for
camera lenses, instrument panels, binoculars, cover glasses
and telescopes.
Prototype laboratory tested.
