Ultra Thin Sapphire Optical Window

Application:
Applications of ultra-thin polished parts include consumer electronics devices, semiconductor components, medical devices,
specialty lighting, analytical processing and quantum computing.. The window does not change the magnification of the 
system.

FineWin wafers offers ultra-thin single-side or double-side polished optical grade sapphire windows and wafers as thin as 
200 microns.
