Your domestic source for precision Sapphire Windows

Sapphire Windows made by Guild Optics are considered among the best in the industry. Our custom sapphire optical components are excellent at protecting delicate lasers, sensors, cameras, and other devices due to their superior strength and scratch resistance. Sapphire Optics can also be used as viewports in high pressure or vacuum situations. Sapphire windows for pressurized enclosures can be made much thinner than their optical glass counterparts due to sapphire’s high modulus of rupture.
With a MOHS hardness of 9, sapphire is second only to diamond plus it transmits from 190nm to 5000nm making it a great choice for UV applications and mid wave infrared. 
Guild Optical is a top tier supplier for many of the best companies in the United States. When precision sapphire windows are required, Guild delivers per the drawing, on time, and on budget. 

Round sapphire optical components are typically the most economical. Rectangular windows can also be made, but usually have to be cut out of round stock. Guild Optical Associates has the machines needed to create any custom shaped windows as well. 

Guild Optical Associates has been perfecting the art of polishing windows made of sapphire since 1990. Many techniques and hours of experience allow us to deliver solutions to customer requirement that meet of exceed their expectations.
