Synthetic quartz preform for optical fibers
Synthetic quartz preform is one of the product groups of Shin-Etsu Chemical that specializes in silicon chemical business. It is a rod based on synthetic quartz of high purity. The inner structure is designed so precisely that any incident light passes through without attenuation. Shin-Etsu Chemical has built a new factory in Kashima, Ibaraki Prefecture, which started operation in October 2001. The production capacity has since doubled, further establishing a system of stable supply.
<Features>
| * |
The high-level and
complex production process is backed by highly reliable quality control and
computer technology, ensuring a stable and high
quality. |
| * |
We were the first company
to produce large-size preforms, and established mass production technology
for preforms 160mmφ in diameter ×1,500 mm in
length. |
|
<Applications>
* Fibers for optical communication,
image guides, and laser transmission |

Synthetic quartz glass for optics
Production technology of optical quartz glass introduced from Heraeus Quarzglas GmbH, Germany together with the excellent synthetic technology of Shin-Etsu Group are the base of development of this synthetic optical quartz glass.
<Features>
| * |
Unlike natural quartz
glass, this product has no granular structure and does not emit fluorescence
under a 253.7 nm mercury lamp. |
| * |
Various grades are
available depending on the presence or absence of
striae, light transmittance,
and laser-proof property. |
|
<Applications>
| * |
Lens materials for
excimer laser steppers |
| * |
Spectrum prism, lens,
windows, mirror for laser, etc. |

Transparent quartz glass for lamps
The transparent quartz glass is produced by our unique tool-free method. The inner and outer surfaces of the tubes are perfectly smooth with no defect.
<Lineup>
| * |
M series of ozoneles
type |
| * |
HERALUX series of natural
quartz glass |
| * |
SUPRASIL-F series of
synthetic quartz glass which has excellent transmittance ranging
from vacuum ultraviolet to infrared |
|
<Applications>
|
|
|
|
Optical fiber coatings
The coating prevents the additional loss of optical information that travels through the optical fiber (quartz glass) by constant reflection caused by microbending. Thus, the coating improves transmission characteristics and also protects the optical fibers against mechanical stress such as lateral pressure applied to the optical fiber.
<Features>
| * |
Liquid silicone rubber
is the raw material, which is highly resistant to
heat and cold and shows
stable performance over a wide range of temperatures. |
|
<Lineup>
| * |
For primaries, for
buffers, for polymer clads |
| * |
Two types of curing
methods are available; heat curing type and UV curing type suitable
for high-speed drawing. |

Optical isolators
The optical isolators are highly reliable optical passive parts, the key components of which are manufactured by Shin-Etsu Chemical. Used in laser modules that forms the light source of optical communication and in joints of optical fibers, they support stable high-speed communication.
<Features>
| * |
They take pride in
compactness and high reliability. |
| * |
The Faraday Rotators
developed by Shin-Etsu Chemical's oxide single crystal growing
technology is used. |
| * |
Shin-Etsu Chemical's
Sm-Co magnet is used. |
| * |
Isolators for 1.31μm,
1.48μm and 1.55μm are included in the lineup. Single
type and double type are available. |
|
<Applications>
| |
They are incorporated
in DFB laser modules used in optical fiber networks (relay system, CATV),
and cut the reflected light. |
