Glass Ball Lenses are excellent optical elements for ameliorate signal coupling between fibers, emitters and detectors. They are fabricated from a single substrate of glass and can focus or collimate light, hinging upon the geometry of the input source. Ball lenses find its main application as a coupling element for optical fibers. Anti-reflection coating may be applied to these lenses to minimize reflection, thereby increasing transmission.

Ball Lenses are generally fabricated with diameter ranging from 0.25 mm to 8.0 mm Each Ball lens is inspected in detail for spotting out any defects, and, of course are well polished & cleaned to perfection, before delivery to customers. In addition, the final components are usually packed in waffle type plastic trays, for the care and safety of material.

Classic Features of Glass Ball Lens are mentioned as follows,

• Uniformly and Precisely Ground.
• Low Scratch-Dig.
• Low Roughness.
• Wide range of optical materials is used.

Materials for fabrication generally encompasses,

• Optical and colored glass products.
• Technical and special glasses
• Low Tg glass materials.
• High refractive index glass materials.

General applications of Ball Lenses include,

• Endoscopy.
• Barcode scanning.
• Optical Measurement Systems.
• Projection Optics Systems.
• Pre-form for Precision Molding.
• Switches.

Half ball lenses are fiber coupling half-sphere lenses that can be simply interchanged with (full) ball lenses if the physical curtailment of an application requires a more compact design. Half balls are also known as Hemispheres. They are a special case of cut-balls lenses.

Half ball lenses are generally fabricated with the diameter ranging from 1.0 mm to 10.0 mm, in various thicknesses as per customer’s need. Dimension Tolerance generally varies in the range ± 0.002mm. Other main parameters considered, while designing these lenses are surface quality and sphericity. The final products are individually packed in waffle type plastic trays. Half ball lens are particularly designed for the use in the field of LED lighting.

Highlighting features incorporate,

• High Precision Dimension Control.
• High Surface Quality.
• Scratch Proof Surface.
• High/ Very High refraction index.
• Small Surface Roughness.
• Very high Heat resistance capability

General applications include,

• Optical Measurement Systems.
• Projection Optics Systems.
• Imaging Optics Systems.
• Astronomical Optics.
• Bar code scanning.

Half ball lenses are ideal for fiber communication applications, endoscopy, and laser measurement practices. There are even more features which we never knew about it!
