Although a variety of Special Optics single and multi-element lenses are useful in diode laser applications, the characteristics of semiconductor lasers often require unique lenses.  The optical components described in this section have been specifically designed to collimate or focus diode lasers that operate within the 670 to 1550 nm range.

The five positive air-spaced doublets described below focus the collimated output of diode lasers operating within the 670 to 1550 nm spectral range.  They may also be combined to expand the 18 mm output of either the Model 54-18-15 or 54-18-23 Collimating Objectives.  The Model 54-18-76N negative doublets is designed to serve as the input element of a Galilean Beam Expander when mated with any of the 0.12N.A. positive lenses.  All six lenses are fully corrected aplanats, so they can be mixed and matched in a focusing or non-focusing configuration to obtain the desired magnification.  With the appropriate antireflection coating, each lens may also be used with visible wavelength lasers.
