Abstract:
1. An auxiliary light accessory for an inspection microscope, comprising: a ring-shaped body adapted to mount to an objective housing of an inspection microscope by means of set screws, said ring-shaped body containing a plurality of light-emitting diodes (“LEDs”) arranged around the ring-shaped body and directed toward a lower surface of the ring-shaped body and oriented to illuminate a subject on a stage of the inspection microscope through a Fresnel lens; two targeting laser optical systems configured to project substantially planar fans of light from the lower surface of the ring-shaped body onto the subject, said targeting laser optical systems oriented so that an intersection between planes of the substantially planar fans of light is collinear with a main optical axis of the microscope; and a control unit for attenuating the plurality of LEDs if the two targeting laser optical systems are illuminated, and for automatically extinguishing the two targeting laser optical systems and re-illuminating the plurality of LEDs a configurable period of time after the two targeting laser optical systems are illuminated.
