Abstract: An apparatus for gradually supplying power to a source of illumination in a microscope, including a power transistor operatively arranged to provide a varying applied voltage to the source of illumination, and, means for biasing the power transistor with a pulse width modulated signal to incrementally increase the applied voltage to the source of illumination in a plurality of discrete steps. The invention also includes a method for gradually supplying power to a source of illumination in a microscope by biasing a power transistor with a pulse width modulated signal to incrementally increase the applied voltage to the source of illumination in a plurality of discrete steps.
