MIRROR SCREWS

These costs are based on the actual efforts and the direct costs of developing these items and associated materials. All of the “mechanical parts” are hand made, using the same or very similar methods and techniques as were used to produce the originals. As in the original mirror screws, all of the mirrors are constructed of stainless steel.  The mirrors are Laser cut.

The Mirror Screws listed here consist of a complete assembly including the mirrors and an axle.    

Mirror Screws are available in two sizes. The 4” inch diameter size provides an image measuring approximately 3” by 4” inches.  This Mirror Screw is available in either 32 or 60  line resolutions.

A larger mirror screw, 6” inches in diameter is also available. It will provide a image measuring approximately  4” by 6”. This mirror screw is also available in the 32 or 60 line resolutions.
