Abstract

An optical system comprising a distal lens assembly defining an optical exit axis; an optical beam combining element; an image sensor; an imaging lens assembly defining an imaging beam path between the optical beam combining element and the image sensor, the distal lens assembly and the imaging lens assembly configured such that imaging light scattered by a sample residing at a distal object plane is collected by the distal lens assembly and directed onto the image sensor by the imaging lens assembly according to an optical imaging beam path; an optical coherence tomography beam delivery assembly configured to deliver, from an optical coherence tomography subsystem, an optical coherence tomography sample arm beam onto the optical beam combining element such that the optical coherence tomography sample arm beam is directed through the distal lens assembly onto the sample, thereby defining an optical coherence tomography sample arm beam path, and such that reflected optical coherence tomography light is collected by the distal lens assembly and directed to the optical coherence tomography subsystem for detection, wherein the distal lens assembly and/or the imaging lens assembly and/or the optical coherence tomography beam delivery assembly comprises a variable focal length lens configured to variably adjust a distance between the distal lens assembly and the distal object plane along the optical exit axis, wherein a focal length of the variable focal length lens is variable within a predefined focal length range.
