To take advantage of our global optical supply chain pricing call us today.

We represent optics companies who have already gone through the process of finding and qualifying reliable optics suppliers that produce high quality optical components. We have global optics and optical supply chain partners who can provide you with reliable high quality ball and drum lenses.
A typical example of optical products we can provide for you:

Ball lenses are used for various tasks such as improving the coupling between optical fibers and the emitters or detectors they interface with. Standard size lenses range from 1.0mm to 5.0mm. Custom made sizes or special materials are also available. All Ball lenses can be ordered with full-surface anti-reflection (AR) coating.

The effective focal length of a ball lens is given by the following formula:

BFL=F - D/2 and EFL=nD/4(n-1)

The Numerical Aperture, NA, of a ball lens is dependent on the focal length of the ball and on the input diameter, d.
NA = 2d(n-1)/nD

A Drum Lens is a variation of a ball lens where a portion of the ball is ground down to a smaller diameter. These lenses are used in similar applications to those of ball lenses. The Drum Lens adds the ability to handle and package it in a different way.

Drum Lens Specifications

Diameter tolerance: +0.0/-0.05mm
Length: ±0.01mm
Surface Quality: 40/20
Coating: None
Diameters from 2.0mm to 4.0mm
Lengths from 2.5mm to 5.0mm
Fused Silica Drum Lenses Available.
