Micro-optical imaging is facilitated. According to an example embodiment, a micro-optical probe arrangement includes a GRIN-type lens probe to direct light to and from a specimen. Compensation optics tailored to the probe and aberrations introduced by the lens are located in a light path through the lens, and compensate for the introduced aberrations. A light detector detects light from the specimen, as facilitated by the compensation optics, and generates data characterizing an image of the specimen.
