WHY ARE SAPPHIRE WINDOWS SUCH HIGH PERFORMERS?
Sapphire windows and flat stock are incredibly hard, strong and
wear resistant:
A sapphire window can be exposed to extreme abradants such as sand
and particulates with minimal effect on the clarity of the window.
This makes sapphire windows the ideal material for a variety of
applications such as: Aerospace windows, downhole and drilling
vision systems, inspection windows, watch crystals and gun sights.
Sapphire windows can take pressure like no other clear material,
making sapphire windows the go-to transparent material for
high-pressure vessels, deep sea windows and sight glasses. Combined
with the exceptional thermal and chemical performance of sapphire,
a sapphire window is the ideal transparency for pressurized
in-process, deep sea and equipment sensors.
Sapphire flats and wear parts are used in applications in which
wear is a problem. Systems like canning machines, slide plates,
V-blocks, flat bearings and pushers utilize sapphire flats and
blocks to extend the lifetime of the equipment and reduce downtime.

Applications:
Optical Windows are flat, plane-parallel, transparent optical
surfaces designed to protect sensors and other electronic
instruments from environment conditions.
Optical Window selection considerations include material
transmission properties as well as scattering, strength and
resistance to certain environments. Their use should not impact on
magnification of a system. Optical Windows can be optically
polished and incorporate an element for diffusing light source to
control illumination.
AR coatings can be applied to ensure maximum transmission
performance for a particular wavelength. The windows are made in a
range of materials including UV Fused Silica, Quartz, IR Crystals
and optical glasses. Our optical window properties include x-ray
protection, non-browning to UV light and light transmission from
deep ultra violet to far infrared.
Optical Windows products include wedges, substrates, discs, flats,
plates, rods, protection windows, laser windows, camera windows,
light guides and domes.
Our Windows are used by scientific and industrial companies across
the world of medical, defence, instrumentation, laser, research and
imaging.
All our Optical Windows can be supplied from a standard range
stock. We also supply custom optical windows made to your
specification, sizes and specific design.
