Microscope Operational Parameters A microscope is to be used to make an accurate length measurement. The mi- croscope objective has engraved markings on it as follows: “Achro” and “20 / 0.50” and “160 / 0.17.” The eyepiece has engraved markings on it as follows: “R15X.” The Feld stop in this Ramsden eyepiece is 15 . 0 mm in diameter. The outside of the eyepiece tube is a standard 23 . 2 mm diameter. Calculate, showing all work, the focal length of the objective. Express your an- swer in mm accurately to three signiFcant Fgures. Calculate, showing all work, the focal length of the eyepiece. Specify the length of microscope tube (from back focal plane of object to front focal plane of eyepiece) intended for this objective and eyepiece. Express your answer in mm accurately to three signiFcant Fgures. Calculate, showing all work, the angular magniFcation of the resulting microscope. Calculate, showing all work, the

Unformatted text preview: diameter of the magniFed area of a specimen object that is seen when viewing through the microscope. Express your answer in μm accurately to three signiFcant Fgures. Cal-culate, showing all work, the apparent Feld of view to the human eye looking through this microscope when the focus is adjusted so that the image appears at inFnity. Ex-press your answer in deg accurately to four signiFcant Fgures. Put your Fnal answers in the spaces provided below. ±ocal length of objective = mm ±ocal length of eyepiece = mm Length of microscope tube = mm Angular magniFcation of microscope = Diameter of area of specimen object as seen through the microscope = μm Apparent Feld of view to human eye with image focused at inFnity = deg...
