Rectangular sapphire windows and square sapphire windows are manufactured regularly at Finewin Wafers. 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.
With a MOHS hardness of 9, sapphire is second only to diamond and it transmits from 190nm to 5000nm making it a great
choice for UV applications and mid wave infrared.
