High precision retro elements mounted in a wall-mount NEMA enclosure with acrylic window.  Suitable for measurements over 1000 meters in clear air.  Up to 45 elements may be accommodated in one enclosure.  The number of elements for any particular application depends on the path length, the opacity in the path and the stability of the launch telescope mounting platform. Figure shown displays the NEMA enclosure with 19 elements.
