Technology / product information

The Ball Lens is a specialized lens with a shorter focal length than conventional convex lenses, designed for light condensation. It is widely used in optical applications such as coupling and collimation in fiber optic communication, sensors, barcode scanners, and endoscopy.

Sapphire ball lenses, in particular, are suitable for a wide wavelength range from UV to IR (0.17–5.5μm) and offer exceptional environmental resistance.

SUGITOH OPTICAL (THAILAND) CO., LTD., based in Samut Sakhon, Thailand, provides high-quality optical products using advanced Japanese technology.
