our company produces optical glass ball lens, and super hemispherical lens. the product features stability, high precision ,good surface quality, batch tolerance less than 0.4um,roundness less than 0.2um,and a wide variety of materials.
it widely used in optical communication, precision instruments, medical instrument, images, etc. with the hard work of our R&D team, our minimum diameter can reach 0.4mm
Optical sapphire ball lens and half ball lens are both made from Al203,
it's ideal for demanding applications (such as laser systems).
They have a lot of advantages:
1/ Stronger than standard optical glass,they have extreme surface hardness, high thermal conductivity, high dielectric constant and
resistance to common chemical acids and alkalis.
2/ Transmits Wavelengths Ranging From UV to Mid-Infrared (0.2 - 5.5µm.)

About sapphire materials for our ball lenses
We only choose the best sapphire material to process the ball lens and hemispherical half ball lenses for our customers. As you know, sapphire has higher performance and higher purity near the center in the process of growing.
So only the ball lens made from this part of the material has better performance.
Sjllaser Technology Limited has developed a new product line!

Diameter Tolerance: ±0.001mm
Roundness less than 0.4um
Material: Optical Glass H-K9L, N-BK7, K-VC89, K-VC80, L-LAH84, LASFH17
Sjllaser Technology Limited manufacture micro ball lens ranges in diameter from 0.3mm to 3mm. Micro ball lens is used to improve signal coupling between Emitters, Fibres, Transmitters, Receivers and Detectors depending on the application. 1.Diameter Tolerance 0.001mm 2.Roundness less than 0.4um 3.Surface Quality is Ra10nm.
Low Tg Ball Lens has the characteristics of low melting and softening temperature, being easily shaped and special optical-mechanical properties, easy to be molded by secondary pressing, suitable for precision pressing of aspherical lenses, which helps to reduce the production cost of batch lenses. Low Tg Ball Lens / Aspherical Lenses are applied in precision molding, such as digital cameras, video cameras, mobile phones, etc.
