Product Description
Optical Window
Optical Windows are flat, plane-parallel plates that are often used
as protective barriers for electronic sensors or detectors from
outside environments. Optical Windows should be selected based on
the material transmission or mechanical properties of the
substrate. Optical Windows do not cause change in the magnification
of a system.

sapphire
glass crystals come in a variety of thicknesses and diameters, are
nearly unbreakable crystals making them highly prized by
watchmakers. These watch crystals can be glued into most watch
cases or pressure fit into most plastic watch crystal gaskets. Each
sapphire watch crystal comes with a slightly polished bevel edge to
give the watch crystal a nice finished look once it has been
installed. These generic sapphire glass crystals can be used to
replace the watch crystals of almost every name brand watch

Rolex watches, saving you both time and money.
