Spherical Projection System Care

Spherical Projection System are precision optical equipment that can be damaged if dropped or crushed. Also the audience should never be allowed to touch any portion of the Spherical Projection System – especially the two first surface mirrors. When setting up the Spherical Projection System, be certain that it is properly positioned on the table. Also be certain that the secondary is securely fastened to the slider when in operation and to the case behind the convex primary mirror when traveling.

Take care when placing or removing the projector not to touch either of the mirrors.

Also be certain that all flashlights, lens cover, and other small items are removed from the Spherical Projection System case before closing. These can scratch the primary convex mirror. Also remember to cover the back area with the plate provided. This prevents dust from entering the Spherical Projection System. The snug black bag for the Spherical Projection System will protect it from scratches and dings when traveling.

The greatest damage happens to a Spherical Projection System in shipping or in a van or truck when a heavy item is placed over it. Because of the fiberglass construction, most of this damage can be repaired and one or both of the first-surface mirrors can be replaced. Such damages are not covered under warranty, but can be provided by ALKOWN Dome-7.
