Macro Magni-Gage Charts are furnished on either glass or a dimensionally stable plastic or mylar. While glass has the lowest coefficient of expansion, Macro plastic materials provide a durable, stable chart and will take rough handling and everyday service. The highest degree of accuracy is maintained and assured on all 3 materials.

GLASS MAGNI-GAGES (distortion free)

Only the finest plate glass is used for Magni-Gages. The Macro special process with sealed image assures uniform line density, maximum durability, and a chart unaffected by ordinary cleansers such as soap, water, alcohol. Edges are carefully ground assuring proper fit to the specified comparator.
