Welcome to
the Mark Optics page for glass and quartz wafer substrates.
Although we cannot possibly list all the various substrates we
manufacture, we hope this will begin to illustrate our extensive
capabilities. These
pages are designed to guide you through our standard
specifications and custom fabrication competencies. If you do not find what you need here, please contact us
with your suggestions.

Some
suggestions:
 The
following three wafers are typical examples of quartz and glass
wafer substrates Mark Optics manufactures for the semiconductor,
telecommunication and display industries.
You may use this as a starting point for creating your
perfect wafer or just fill in our
Wafer
Quote Form and
specify the diameter, material and your application.
That is all you have to do and we will send a quotation
to you immediately.
Semi-Standard
Wafers:
These are
standard quartz wafers used primarily for semiconductor
process verification and are sometimes referred to as
"dummy" wafers. By specifying the surface roughness, this type of wafer is
often used in plasma bonding or anodic bonding to
silicon wafers (SOQ).
A double side polished wafer typically transmits greater
than 90% between 260nm to 2.60 micron and has a refractive index
of 1.4585.
Tele-Wafers:
Our
tele-wafers
typically transmit visible through 2.40 micron when a CTE (coefficient
of thermal expansion) similar to silicon is desired. These
wafers can generally be used in thin film deposition, anodic
bonding and as optical aligners to silicon wafers.
Refractive indices range from 1.472 – 1.510 depending
on material.
Opti-Wafers:
Our
optical wafers allow the maximum transmission from 180nm
through 2.60 micron where our custom processes have effectively
minimized surface defects and sub-surface damage (“micro-cracks”
and fractures) that can be introduced during fabrication.
This is optimal when your application is requiring
the lowest light scattering characteristics.
