Sapphire Ball Lens

Description

Feature:

Sapphire and Ruby Ball Lenses are both made from Al203. Ruby or Ruby-Doped sapphire owes its red color to traces of chromium oxide (chromium content for ruby balls is typically >0.5%). While their physical and chemical properties are similar, Sapphire has superior optical transmission. Ruby Ball Lenses are easier to see and handle for physical applications. Sapphire and Ruby Ball Lenses are ideal for improving signal coupling between fibers, emitters, and detectors. They are also used in endoscopy, bar code scanning, ball pre-forms for aspheric lenses, and sensor applications. Sapphire and Ruby Half-Ball Lenses are also available.

sapphire, and BK7.  UV grade fused silica can be used for UV, VIS, and NIR
applications, and is a stable substrate with a low coefficient of thermal expansion. BK7, a boro-crown glass, has an index of refraction of about 1.51 and is often used for visible light. Sapphire has a cost premium but does also
provide better optical transmission. It is suitable for UV and IR applicatio
