Sapphire Windows

Optical Grade Sapphire Windows

Sapphire WindowsSapphire Windows made by Guild Optics are considered among the best in the industry. Our custom optical components are excellent at protecting delicate lasers, sensors, cameras, and other devices due to their superior strength and scratch resistance. Sapphire windows can also be used as viewports in high pressure or vacuum situations. Sapphire pressure windows can be made much thinner than their optical glass counterparts due to sapphire’s high modulus of rupture.
