An optical system suitable for use in an optical instrument such as a handheld optical probe, the optical system including a scanning element and an objective, the objective including a variable focus lens that can be electronically controlled to change the focal length of the optical system. In some embodiments, the optical system can axially and laterally scan a subject material by sequentially focusing at an axial depth using the variable focus lens and laterally scanning the material at that depth using the scanning element.
