Description

          Made of
Made of high-purity crystal, the quartz rings are manufactured into rough
material by H2-O2 flamefusing. Its SiO2 content is more than 99.9999%,
and it is clear and bubble free. It is washed and shaped under strict control,
and thus enjoys homogeneous density and free of suspended substances and
other impurities. The cross section of the ring is rectangular, which makes
it suitable for long term vapour deposition of multi-layer optical films.
The quartz ring is a whole piece, so it may be evaporated evenly when
heating by the electron gun. Thus, it may achieve films of even thickness
and homogeneity. Therefore, quality of the optical films are improved and
may reach the Class I quality requirements for précised optics. It could be
used widely for vapour deposition of AR films and multi-layer films
which request the highest surface precision in the world optics industry.
