Cubic Dioptrograph
GPM Model 211 Price: $8,689
Product Details
The only drawings that can be used for measurements are those for which the projection was made on paper by parallel rays. This is why the use of the dioptrograph is recommended.
A diopter with a graticule is placed on the glass plate. The graticule is fixed, such that it can rotate, to a reference point on the pantograph. The opposite reference point carries a pencil that can trace outlines on the paper.
Not only 1:1 scale is supported - you can up and down scale too.
