Description

Sapphire Windows from Guild Optics are considered among the best in the industry. Sapphire windows are excellent at protecting delicate optics due to their superior strength and transmission. Sapphire windows can also be used as viewports in high pressure or vacuum situations. Sapphire pressure windows can be made much thinner than other optical glasses due to sapphire’s high modulus of rupture.

The following are sapphire round windows that Guild Optical Associates currently has in stock and ready to ship. Note that the prices go down if you want a quantity larger than what is shown.
