LENS SELECTION GUIDE FOR LASER TO FIBER COUPLERS
The following set of tables list the standard lenses available from OZ Optics. The tables are broken up into two maincategories - Lenses for Pigtail Style Couplers and Lenses for Laser to Fiber Couplers with Receptacles (non-contactstyle) or Adjustable Focus Couplers.

SELECTION GUIDE 1: LENSES FOR PIGTAIL STYLE COUPLERS
GRIN LENSES AND C-LENSES: Select these lenses when cost is your main concern. Available wavelengths are 400 - 1600nm.

* The 6.3AG lens is an air-spaced achromat specifically designed for very high power coupling applications.
†The 6AG lens is a doublet lens but not a true achromat lens. It is optimized to correct for spherical aberration inthe UV range, and not chromatic aberration.

ASPHERIC LENSES: Select these lenses for best performance in the infrared or applications requiring excellent
polarization maintaining behaviour. Available wavelengths are 400 - 1600nm.
