Ball lenses are transparent spherical ball, which has small diameters, sometimes with a few millimeters or even less than a millimeter. It has characteristics of good surface quality, good light reflection, directional reflection, high impact strength, and light weight, etc., which are applied in various areas, such as chemical, aerospace, transportation, light industry, medical, etc.

The Application of Ball Lens

Ball lenses are great optical components 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. Ball lenses are manufactured from a single substrate of glass and can focus or collimate light, depenging upon the geometry of the input source. Half-ball lenses are also common and can be interchanged with full ball lenses if the physical constraints of an application require a more compact design.

Spherical lenses are the most used lenses in optical systems design, JT produces high precision spherical lenses in plano convex, double convex, and plano concave, double concave, meniscus, achromatic doublets and triplets, develop and manufacture high-end optics from 0.5 mm to 600 mm in diameter, which use in many different fields of application, from laser material processing to biotechnology, medical technology, defense and security and the semiconductor market, meeting the most stringent requirements.
