A special type of thick biconvex optical lens is a Ball lenses that usually has a sphere geometric shape. These are made of a single material such as BK7 or other optical glass/Fused Silica/CaF2 which is a commonly used material for ball lenses.
The smallest lens we produced is < 0.5 mm. We can process ball lenses using all types of glass material. Our price for PV industry may be as low as USD0.02/pcs. We are developing CSD-based AR-coating to provide a low-cost PV-coating solution.

ALLOWABLE BALL DIAMETER VARIATION is the largest variation in diameter found in any one ball from the sample lot inspection.
ALLOWABLE DEVIATION FROM SPHERICAL FORM is the greatest radial distance in any radial plane between a sphere circumscribed around the ball surface and any point on the ball surface.
SURFACE ROUGHNESS is all those irregularities which form the surface relief but are not deviations of form or waviness. The measurement of this characteristic is to be made with equipment meeting the requirements of and in accordance with Standard ANSI B 46.1.
BASIC DIAMETER TOLERANCE is the maximum allowable deviation in any ball mean diameter from the basic diameter ordered.
ALLOWABLE LOT DIAMETER VARIATION is the difference between the mean diameter of the largest ball and that of the smallest ball in the lot.
