OpTek laser lensing produces high performance lens forms directly onto the end of an optical fiber.  The non-contact lensing process is incredibly fast and uses on-line imaging to ensure accurate centration of the lens to the fiber.  The superior optical quality of the surface and exceptional control over the lens ensures maximum coupling.

lensing machineThe optical quality of the laser cleave is unsurpassed. In telecoms applications the reproducibility of the lens and the exceptionally low-scatter of the processed surface provides enhanced performance.

Wedge lens In all cases, the speed of the Laser Lensing process gives unbeatable cost-effectiveness.

Laser Lens Advantages

Lens Radius

  • <5-15µm for standard process
  • Standard tolerance is ±10%

Precise Lens Position 

  • Lens position can be referenced to fixed feature on the fiber such as metalization


  • 10 to a few 10's of seconds per lens (depends on type)

Non-contact process

  • No tool wear, or mechanical damage to the fiber

Cleave Orientation

  • Lens orientation to stress rods
  • Orientation to ferrule

Optical quality

  • Lower scatter than conventionally polished ends 

High damage threshold 

  • Laser lensing produces high damage-threshold facets for use in fiber-laser applications

Geometric Form 

  • Choice of precise shape of end-face, including angled lens forms and removal of scrap angles
  • This field is for validation purposes and should be left unchanged.
