Potapenko Glass & Filters
Products: Optical Material, Chemical Certificate
The present page certifies high-end optical glass type that has
chemical-creative synthetic industrial origin. That is produced by the
chemical technologies in Ukrainian Optical Glass Factory. We send you the
standard test-report and the glass datasheet to delivered glass as you
orders. Note: We un-open our synthetic chemical content: fundamental and
principle elements, at our test report. The standard test certificate
is optical defects in Gost's optical materials, only. Nevertheless, We
inform you, here now.
Trade Mark:
Crown-Glass, Flint-Glass
The optical glass trade marks traditional and well-known are crown-glass and
flint-glass in the specification GOST No. 3514 Optical glass -
Specification.
Note, Free
Natural Glass Materials:
Quartz, Volcanic
Glass
The geologically natural crystal quartz and volcanic glass represent natural
glass materials found in free-nature.

Facts in Optics
The
Gost's optical glass specifications close to international fabricants, e.g.
Schott glass & Hoya glass. There are special optical glass, which melts
exclusively in Ukrainian Optical Glass Factory. The super optical glass-work
technologies take place, only some world factories have mastered optical
glass, and optical color glass. The world's historical glass-work facts in

Synthetic Chemical
Content: Fundamental
Elements
The
Gost's optical glass materials are produced by an melting oxides in
glass-forming substance. There are multi-component material. The fundamental
optical glass-forming chemical components as follows: silicate, phosphate,
borate.
SiO2 B2O3 P2O5 GeO2 TeO2
Synthetic Chemical
Content: Principle Elements
In the course of Ukrainian optical glass-work's long history, many optical glass
have been designed, that have been selected as "recommends product line". Also
ea. optical glass type has its own properties that are closely connected with
the principle chemical element contained: fluorine, aluminum, barium, zinc,
lanthanum, lithium, titanium, tantalum and beryllium.

Glass Type
All the more, plumbic oxide (PbO) and arsenic oxide (As2O3) are not principle chemical elements in optic glass, when avoided arsenic oxide as a refining agent, and plumbic oxide was essentially replaced by titanium oxide. We are not adding the prefix N/S/L/E/K and others to indicate which of the glass type is eco-optical glass and environmentally safe. Our glass types do contain nil/lowest plumbic and arsenic per cent, when the toxic chemical glass elements substituted ecological chemical elements...
