Rectangle Sapphire Windows

Rectangular sapphire windows are excellent at protecting delicate optics due to their superior strength and transmission. Rectangular sapphire windows can also be used as viewports in high pressure or vacuum situations. Square sapphire pressure windows can be made much thinner than other optical glasses due to sapphire’s high modulus of rupture.
