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.
