Abstract: An illumination module may include a laser diode array configured to emit laser radiation; a phosphor illumination unit that is configured to emit phosphor radiation following an exposure to the laser radiation; a multiple-angle illumination unit; and intermediate optics that is configured to convey the phosphor radiation to the multiple-angle illumination unit. The multiple-angle illumination unit is configured to receive the phosphor radiation and to dark field illuminate a region of a sample wafer from multiple angles during inspection of the wafer.

Abstract: An illumination module that may include a LED driver; a group of light emitting diodes (LEDs) that comprises at least one LED; the group of LED is coupled to the LED driver; wherein the LED driver is arranged to activate the group of LEDs by driving a high current short duration driving signal; and wherein the group of LEDs is arranged to emit at least one light pulse in response to the high current short duration driving signal.
