A custom-made compound microscope (see the figure below) with an objective lens with a focal length of 3.55 cm, an eyepiece lens with a focal length of 6.30 cm and a barrel length of 27.5 cm is used to view a 0.100 cm specimen mounted on a microscope slide.

A custom-made compound microscope (see the figure below) with an objective lens with a focal length of 3.55 cm, an eyepiece
lens with a focal length of 6.30 cm and a barrel length of 27.5 cm is used to view a 0.100 cm specimen mounted on a microscope
slide. Since the microscope is custom-made, it varies slightly from a standard production microscope in that the object distance
for the objective is so much larger than the focal length of the objective that we cannot set the object distance for the objective
equal to the focal length of the objective. However, the image formed by the objective is close enough to the focal point of the
eyepiece that we are justified in setting the object distance for the eyepiece equal to the focal length of the eyepiece. Finally, the
microscope is being used by a lab technician with a near point of 33.0 cm. (Use the exact values you enter to make later
calculations.)
