Single crystal sapphire
Marketech provides sapphire substrates, optics, windows and engineered ceramics in either standard sizes or custom created for your application.
Sapphire has a hexagonal/rhombohedral structure and a number of properties are dependant on the orientation of the crystal. For epitaxial growth of films, different orientations will offer a range of lattice constants to match the epi material.
Sapphire Substrates for Blue LEDs
High purity optical grade, epi-ready wafers for blue LED applications are available. See table for standard specifications. Please call for pricing and availability of custom specifications.
Optics and Windows
We offer sapphire windows and sapphire optics - up to 8" diameter and as small as a few millimeters. We can provide various A/R coatings as needed.
Because of its unique properties, sapphire is often machined into precision shapes for instruments and high temperature applications. Sapphire can be bonded to alumina or sapphire as well as other metal parts using glassy or non glassy fritz; or it can be metalized and brazed into metal holders.
