Can a glassless mirror be used as an optical or front surface mirror?
Yes, a special grade of glassless mirror (94% reflectivity) is made specifically for use as front surface mirrors for optical purposes. These are available on special order (call for quote) and are most often used instead of glass when large size optical mirrors are required. We suggest that for optical applications, the projected image be contained within 1″ of the edges of the glassless mirror surface to avoid minor image distortions that would be magnified in projection. Glassless mirrors used for general purposes have a reflection of 85-86%.
