Resumen:

In this work we design a Hartmann-test like screen in such a way that we have a uniform distribution of bright spots of the same size spots; that is what we called a null Hartmann screen. The design of this screen is based on the knowledge of the caustic surface by refraction which is also called diacaustic. This design is intended to make straightforward the detection of the spots for the measurement of the longitudinal spherical aberration of the lens in order to calculate the refractive index of a lens under test.
