Integrated Globes Apparatus

 

The globes are brushed aluminum  and the stand  stainless steel .

The globes’ dimensions are identical as is their internal configuration.

The apparatus is designed to  measure transparency  of substances. 

A lever lowers the sprung lower globe to allow a thin specimen

of the test substance to be placed over an aperture

between the two globes and  release of the lever  fixes the specimen in position.

 On  switching on the light a meter  indicates how much light passes from one globe to the

Other which then gives a measure of transparency.

American patents, otherwise only name is ‘Sud’ Probably c. 1960 

 

We have not seen one of these before  but nobody visits us without 

remarking on this striking apparatus.

A wonderful show item
