A certain microscope consists of an objective lens, (Lens 1), and a tube lens (Lens 2). The object is placed at the front focal plane of the objective lens and the image is at the back focal plane of the tube lens. The tube lens has a focal length of 200mm. The objective is labeled 20X, which means that the magnification will be 20 when used with this particular tube lens. The working distance (the distance from the object to the front vertex of the objective is given in the instruction manual as 7 mm. The lenses are separated by the sum of their focal lengths. Assuming thin lenses what is the matrix for the combination?

Now the objective isn’t really a thin lens (or even a simple one). Where is its front principal plane located?

Now you have bought the microscope objective talked about above, but you want to build your own microscope. Your tube lens has a focal length of 100mm. You will change the spacing of the lenses so that it is still the sum of the focal lengths. What is the magnification of your microscope.

The distance between the eyepiece and the objective lens in a certain compound microscope is 21.4 cm. The focal length of the objective is 0.480 cm, and that of the eyepiece is 1.50 cm. Find the overall magnification of the microscope. (The near point of the eye is 25 cm. Assume that the object is placed at the focal point of the objective lens, and one places the eyepiece at the near point of the eye.)

Where is the object placed for a microscope? Relative to the location of the objective lens, where is the image formed by the objective lens? In order to have a microscope (not the relaxed eye condition), where does the image of the objective lens have to form relative to the eyepiece? What type of image is produced by the eyepiece for this condition? (real or virtual, magnified or minified, inverted or upright? In order to have a microscope (relaxed eye...

1) Suppose you install an objective lens that gives the microscope a total magnification of 360x. What is the total magnification of this objective lens? 2) Ocular and objective lenses are available in many different magnifications. Give at least two combinations of ocular and objective lenses that would each give a total magnification of 300x.

A microscope has an objective lens with a focal length of 16.22 mm and an eyepiece with a focal length of 9.28 mm. With the length of the barrel set at 31.0 cm, the diameter of a red blood cell's image subtends an angle of 1.43 mrad with the eye. If the final image distance is 31.0 cm from the eyepiece, what is the actual diameter of the red blood cell?

A) The medium-power objective lens in a laboratory microscope has a focal length fobjective = 4.00 mm . If this lens produces a lateral magnification of -37.0, what is its "working distance"; that is, what is the distance from the object to the objective lens B) What is the focal length of an eyepiece lens that will provide an overall magnification of -115? Assume student's near-point distance is N = 25 cm.

The tube length in a certain compound microscope is 25 cm. The focal length of the objective lens is 2.1 cm. The clearest image is formed when an object of height 1 mm is placed at a distance of 2.3 cm from the objective lens. Determine: (i) The position of the intermediate image, (ii) the focal length of the eye piece, that will place the final image at the near-point, (iii) the total magnification of the microscope and the height...

A simple camera telephoto lens consists of two lenses. The objective lens has a focal length f1 = 38.7 cm . Precisely 36.3 cm behind this lens is a concave lens with a focal length f2 = -10.0 cm . The object to be photographed is 3.97 m in front of the objective lens How far behind the concave lens should the film be placed? What is the linear magnification of this lens combination?

A microscope with an objective of focal length

A microscope with an objective of focal length 1.8 mm is used to inspect the tiny features of a computer chip. It is desired to resolve two objects only 400 nm apart. What diameter objective is needed if the microscope is used in air with light of wavelength 550 nm?
