Ball Lenses, also known as Fiber Coupling Spheres, Fiber Coupling Ball
Lenses, or Spherical Ball Micro Lenses, are generally used for fiber/laser
coupling or collimation. Standard size lenses range from 0.15mm to 10mm.
Custom-made sizes or special materials are also available. AWI supplies
custom-made Ball Lens as large as 40mm in diameter to customers in North
America and Europe. All Ball Lenses can be ordered with full-surface
anti-reflection (AR) coating.

DEFINITIONS:
Ball Diameter Variation:
The difference between the largest and the smallest actual
single diameter of one ball. The diameter of each ball is
measured by using two parallel planes that are tangent to
the ball:
So the Ball Diameter Variation is D
max - D min.
Deviation from Spherical Form (Sphericity):
The greatest radial distance in any radial plane between
a sphere circumscribed around the ball surface and any point
of the ball surface:
In other words, a sphere with radius 'Re' is defined such
that it can fully enclose the ball. The distance from the center
of the sphere to the lowest point of the ball is defined as 'Rx.'
Then the Deviation from Spherical Form is equal
to Re - Rx.
