The curvature is tested from time to time by a spherometer, and the tool is increased or decreased in curvature by turning it on a lathe so as to cause it to grind the glass more at the edges or in the middle according to the indications of the spherometer.
The process of fine grinding is continually checked by the spherometer, and the art consists in knowing how to move the grinding tool so as to make the lens surface more or less curved.
After a little practice it will be found possible to bring the glass exactly up to the required curvature as tested by template or spherometer.
The two glass-grinding tools are then ground together by hand (see § 53 and § 61), the spherometer being employed from time to time to check the progress of the work.
Before the grade of emery is changed all three surfaces must agree, as nearly, at least, as the spherometer will show.
