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 email us with any 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.
