Abstract

A Light-Emitting Diode (LED) illuminator-condenser capable of supplying bright-field, dark-field, fluorescence, oblique, and phase-contrast illumination under Köhler-like conditions. A single lens may be permanently focused on the specimen plane. Illumination conditions may be made by a combination of uniform LEDs, collimating masks and diffusers. LEDs may be arranged in one or more ring-shaped patterns.
