AGW-250 Filter

A base lens of True Didymium™ glass filter plus your choice of a full coverage welding filter in shades 3, 4, 5, 6, and 8.

Aura developed the AGW-250 lens to answer requests for improved infrared radiation protection while also reducing the light level perceived by the eye.

It comprises a base glass lens of our exclusive True Didymium™ with a thin layer of either shade 3, 4, 5, 6, or 8 Green Welding (full coverage) laminated to the base lens. This is very desirable when working with high-pressure torches and glass, requiring extremely elevated temperatures. 

Suggested uses are where there is a need for attenuation of bright illumination, such as that generated when working Pyrex®, quartz, Vicor®, platinum jewelry work, and any operation where the artist spends prolonged periods of time gazing into a high-temperature furnace or fire pit.

Quartz workers must use a minimum of Shade 8!

The AGW-250 filter is available in non-prescription (Plano power) and single vision prescription forms only.

Thickness Advisory: This filter is thicker than normal lenses. In non-prescription form, it is approximately 5 mm thick. 

Shade 8 is Custom Made and Not Returnable except for manufacturing defects. 

Protected under the United States Patent Number 6,612,697.
