A long, wedge-shaped coverslip about 0.20 mm fat at one end and 0.10 to 0.12 mm at the another end coated chemically with a silver movie on which are ruled horizontal lines. at every variation in thickness of 0.01 mm there are vertical lines. By means of oblique illumination and by focusing on various portions of the plate, it is possible to determine the optimum coverslip thickness for any objective and also, for microscopes with drawtubes, the pipe length for excellent objective performance. The approximate freedom from spherical and chromatic aberrations can also be estimated. Little isolated bits of silver around the edges of the lines form good objects for the star test
