Remarks on T-Grain Technology Applied to Astrophotographying plate. As Dr. Millikan explains us, this increase in D.Q.E. can result in an increase in Signal to Noise ratio (i.e. increase in co. trast or decrease in granularity) or in an increase of plate speed.

An invention spreading so rapidly must have fulfilled a basic need — the need for a large field with good image quality over a substantial wavelength range.
