Sapphire Ball Lenses

Photonics Buyers' GuideKnight OpticalRequest Info
Sapphire Ball LensesKnight Optical offers a range of stock sapphire ball lenses, for use within fibre optics, signal coupling and barcode scanners. Sapphire (Al2O3) is one of the hardest minerals and optical materials available for use in the range from UV up to 5µm making it ideal as a protective window for camera systems. The key feature of ball lenses is their short back focal length allowing for precision coupling where size or space is a limiting factor in the system. Ball lenses are typically used in pairs with one lens acting as a collimator for the second to focus the light back into the coupled fibre. Where a more compact solution is required a half-ball lens is typically more suitable.

Typical specs:    •   Material: Sapphire    •    Diameter Tolerance: +/-2.5µm    •   Figure (sphericity): 1λ    •   Focal Length Tolerance: ± 0.2% (<10mm) ± 2.0% (10-1000mm) ± 5.0% (>1000mm)    •    Wavelength Range: 0.17 – 5.5µm    •  Surface Quality: <40-20 Scratch/Dig

We hold a large inventory of sapphire ball lenses. Stock sizes from 0.5 5mm to 10mm diameter. Custom sizes available to quotation. Half ball lenses also available.
