Material is BK-7, sapphire! For barcode scanning, sensor applications, etc.
A "ball lens" has a shorter focal length compared to a regular convex lens (single lens) and is mainly used for focusing light. It is suitable for applications such as focusing light into optical fibers, coupling, and collimating light emitted from fibers. Sapphire can be used over a wide range of wavelengths from ultraviolet to infrared (0.17μm to 5.5μm) and has better environmental resistance than BK-7. 【Specifications】 ■ Material: BK-7, Sapphire ■ Refractive Index - BK-7: 1.51680/nd, 1.51872/ne - Sapphire: 1.7682/nd ■ Design Wavelength: 587.6nm (d line) *For more details, please download the PDF or feel free to contact us.

Company information
This is an optical manufacturer with over 110 years of history, originating from Sugita Glass Instrument Store founded by Tōtarō Sugita in 1906 (Meiji 39). The main business is the research and manufacturing of glass, and for many years, it has supplied a wide variety of glass products to various fields. In 1982, the company changed its name to Sugito Co., Ltd. and promoted business expansion, designing, developing, manufacturing, and selling optical elements such as optical lenses and prisms, glass products like special lenses and magnifying glasses, as well as optical products and components including macro zoom lenses, microscopes, various scopes, and inspection equipment. Additionally, in 1993, a factory was newly established in Thailand to enhance the production capacity of glass products and lenses. The company keeps standard optical elements and lens systems in stock at all times and can sell from a single unit. It also handles the design, development, and manufacturing of optical elements and lens systems according to customer requests, so please feel free to inquire.
