Aluminium Oxide Ball Lens

Ball lens have shorter focal length than convex lens, Spherical lenses have
greater magnification than common convex lens, minimizes the distance from
spherical lens to optical fiber, mainly used in fiber application.
Substrate  aluminium oxide
Diameter 0.5-100mm
Thickenss 5-20mm
Dimension Tolerance  +/-1um, +/-2um, +/-3um
Ovality 1um, 2um 3um, 3um 
Shape  ball or half ball, hyper-hemispherical lens
Surface Quality 60/40-10/5 as request
CCRQ can supply BK7/K9, Sapphire, Ruby, Fused Silica(JGS1,JGS2,JGS3), Znse,
Silicon ball lens and half ball lens, it can improve the signal quality and
detectors quality, ball lenses also used in endoscopy barcode scanning and
laser measurement application, half ball lenses also have above functions.
