AUR-92 Transmission Chart

This material was originally developed for enhancement of the primary colors Red, Green, and Blue. The spectral analysis of this glass filter shows it to be very efficient in eliminating the sodium flare, along with very good ultraviolet protection to 390 nm, and much improved infrared protection in the 750 nm to 1000 nm range.

A side benefit of this filter is the apparent improvement in judging the color temperature of the glass while working it. The observed color is very comfortable when viewing glowing heat sources for long periods of time.

Suggested uses are: lamp working of soft glass beads and small sculptures. Not recommended for work on very high temperature glasses for long periods of time.

AUR-92^® bifocals are supplied with Aura's exclusive "Uniform Density" feature. A 3.2 mm thick wafer of AUR-92^® is laminated over a thinly ground glass bifocal lens - giving you the same filtration through the bifocal as around it. No other manufacturer can make this claim. This lamination process also makes for a safer lens.

Lenses are available in plano (non-prescription), single vision, and laminated bifocals, trifocals and progressive style lenses.
