Aim Controls has made a variety custom heliostats.  Shown below are two examples.

The first mount is an automated Alt/Az heliostat that finds the Sun each day, tracks continuously (even through clouds) and is auto corrected with a video or CCD camera.  Control can be through a locally mounted VGA touchscreen, IR handheld remote, or USB 2.0 port.  This Atl/Az style of mount has a 10 inch precision bearing in the Azimuth axis and can be used for optical tube assemblies up to 14" diameter.  The same mount can be used for general astronomy.

The second mount is a permanent installation at the University of Toronto.  It employs an Alt/Az mount, custom mirrors and mirror holders, and stainless steel rectangular cover with automated slide-off cover.
