A microscope insert, comprising: a beam splitter configured to receive first light from an object, the beam splitter directing a first portion of the first light in a first direction to a viewing device and directing a second portion of the first light in a second direction; a camera configured to receive the second portion of the first light from the beam splitter and to generate a first signal representing the object; a processing unit configured to receive the first signal representing the object and determine characteristics of the object by analyzing the first signal, the processing unit further generating a second signal representing information relevant to the object; a display device configured to receive the second signal from the processing unit and generate a graphical representation of the information based on the second signal, the display device transmitting second light corresponding to the graphical representation; and a polarizer element configured to modify a polarization of the second light from the display device; wherein: the beam splitter receives the modified second light from the polarizer element and directs a first portion of the modified second light in the first direction to the viewing device; and the first portion of the modified second light and the first portion of the first light from the object are combined for simultaneous viewing of the graphical representation and the object by the user; characterized in that: the beam splitter is further configured to direct a second portion of the modified second light in the second direction to the camera, and the camera generates, based on the second portion of the modified second light, a third signal representing the graphical representation generated by the display device; wherein the processing unit is further configured to: determine a field of view based on the first signal from the camera; compare the third signal and the first signal; and adjust the graphical representation generated by the display device based on the comparison; and wherein the polarizer element is configured to adjust the polarization of the second light from the display device so as to adjust a ratio between the first portion of the modified second light and the second portion of the modified second light. a beam splitter configured to receive first light from an object, the beam splitter directing a first portion of the first light in a first direction to a viewing device and directing a second portion of the first light in a second direction;
