Next, use the Microscope Focus slider to obtain the sharpest image specimen possible. WebSome manufacturers have produced tables for converting convex radii to concave. The correction factors for radii for concave surfaces are greater than for convex surfaces and range from 0.02 mm for steep radii to 0.04 mm for flat. Thus, for lenses used in practice, it is sufficient to add 0.03 to the radius reading given by the keratometer. green motion age restrictions
