Methods for directing an optical beam and for making an apparatus for directing
an optical beam are described. One such method may include applying a first force
to a plate to move the plate from a first angular orientation to a second angular
orientation wherein the plate contacts a stop in the second angular orientation.
A second force can be applied between the plate and the stop to hold the plate
against the stop in a plane substantially parallel to a substantially planar surface
of the stop. An apparatus for directing an optical beam may be made by coupling
an array of plates to a base assembly wherein each plate is movable between a first
angular orientation and a second angular orientation. An array of apertures may
be formed in a stop assembly wherein the stop assembly is coupled to the base assembly
and each aperture is positioned to contact its respective plate when the plate
is in a second angular orientation.
