The term 'microscope lens' is composed of two parts: an OCULAR lens (6 letters) and an OPTIC lens (5 letters). An OCULAR lens is the lens closest to the eye, which magnifies the image seen through the microscope. The OPTIC lens is the lens furthest from the eye, which focuses the light onto the specimen being viewed. Together, these two lenses work together to magnify and focus the image seen through the microscope.
