Micro Ball is precisely manufactured from optical glass. It is
used as a high precision ball lens in optical communication
systems and as a lens for specialty optical equipment such
as endoscopes.
Features
Deviation from spherical form for grade "S": less than 1μm.
Comparative difference of diameters: 6μm max.
Surface roughness: 100Å max. (grade "S" or "A")
Range of diameters: 0.3 - 7.0mm
Properties

Dimensions
Diameter variation: Difference between maximum diameter
and minimum diameter of a ball
Deviation from spherical form: Maximum distance between
the minimum spherical surface circumscribing micro ball
and each point of balls.
Lot diameter variation: Difference between the diameter
of the largest ball and that of the smallest ball in a
