Technology / product information

Unlike standard lenses, the Half-Spherical Lens features a convex shape without edges. It has a positive focal length and is used for applications such as image magnification and light focusing. Its ability to efficiently collect light incident on the lens surface makes it suitable for high-magnification objective lenses, fiber-optic communication, endoscopy, optical pickup devices, and laser measurement systems.

While the product comes uncoated as standard, custom specifications and tailored options are available.

SUGITOH OPTICAL (THAILAND) CO., LTD., based in Samut Sakhon, Thailand, provides high-quality optical components built on advanced Japanese technology, meeting the diverse needs of domestic and international customers.
