Optical
Applications
Sapphire
Windows
Sapphire Windows will exceed other optical materials in harsh environments,
providing a barrier between elements. This is due to sapphire material’s
high mechanical strength, temperature stability, wear resistance
and chemical inertness.
Other window materials
we supply are Quartz, Calcium Fluoride, BK-7
Typical applications—Industrial
and Medical OEM’s—Air and Gas Analyzers/Monitors, High
Intensity Xenon Lamps, Cryogenic View Ports, UV and IR Windows and
Lenses, Detector and Pressure Cells, Photodiodes, Bar Code Readers.
Optical Balls Lenses & Hemispheres
We have over 45 stock sizes of Sapphire, Ruby, Quartz, Glass, and
Cubic Zirconia balls & hemispheres. Off the shelf sizes from
Dia. 005" up to .375", and larger sizes available.
We
offer Grade 25 off the shelf and routinely supply Grades 5 and 10.
Please refer to the AFBMA grade chaft here.
Typical
Applications: Fiber Optics, LEDs, Flow Meters, Bar Code Readers

Basic diameter:
The size ordered which is the basis to which the basic diameter
tolerances apply. The basic diameter is specified by a fraction
plus a decimal or a decimal only to the sixth place. (example:
1/4'' + .0002'' or .2502'' - 15/64'' + .0003'' or .234675'').
Basic diameter
tolerance: The maximum allowable deviation of any ball diameter
from the basic diameter, in any shipments to fill orders for
that basic diameter.
Diameter tolerance
per ball: The permissible difference between the largest diameter
and the smallest diameter measurable on one ball.
Diameter tolerance
per unit container: The permissible range of the average diameters
of the individuals balls within any one unit container.
Grade: The numerical value of the diameter
tolerance per ball expressed in a millionth of an inch. |
