H-K9L Glass Half-Ball Lens

Optical Ball Lens are highly transparent spheres made of optical glasses.They are used as fiber interconnects in telecom and expanded beam connectors.

Optical Half-Ball Lens (Optical Hemispherical Lens) are ideal for applications such as fiber communication, endoscopy, microscopy, optical pick-up devices, and laser measurement systems.

Optical Ball lens made of kinds of materials are also available, such as HK9 optical ball lens (equivalent to Schott N-Bk7 Glass Ball Lens),Schott N-BK7 glass Ball Lenses are glass spheres commonly used in fiber optic applications. N-SF11 glass ball lens, Sapphire Glass Ball Lens, ruby glass balls,UV Fused Silica Ball Lens etc. They are used as fiber interconnects in telecom and expanded beam connectors. Large Optical ball lenses have been successfully used as collectors in LED lighting systems and medical devices. Optical ball lens has high coupling efficiency and should be much easier to align than traditional lenses due to its physical shape.

Larger optical ball lens is easier to handle and ease the sensitivity of translational alignment. However, smaller spheres or Mini Ball Lens fits into smaller packages.
