• Introduction to Light Microscopy: The Compound Microcope

  Why is the microscope called the compound microscope? The microscope has two lenses: the ocular lenses use the real image formed by the objective lens as its object and produces the virtual image that the viewer sees.

• Light Microscopy: Refraction, refractive index, resolution and numerical aperture

  It can be either simple microscope or compound microscope. 1) Refraction - Refraction occurs when light goes from a medium of one density or refractive index to one of another.

• Calculating Microscope Lens Magnification

  This is a step by step solution to a problem of calculating the lateral magnification of a microscope system given the object position and the focal lengths of the objective and the ocular lenses.

• Microscopy: total magnification, depth of field

  Question 2: How do you calculate total magnification of a specimen viewed by a light microscope? What is the total magnification of images viewed under each of the four lenses of a light microscope?

• What is the microscope?

  Do not tilt the microscope too far through. (Teacher should demonstrate how to carry the microscope.) The microscope should be kept covered to keep dust from the optical lenses (systems).

• Various Types of Microscopes and Their Uses

• Light and Dissecting microscopes.

  The light either passes through the object (in the case of a brightfield or compound microscope) or is reflected off the specimen (like that seen in a dissecting microscope).

• Microscope

  The microscope has a tube length L=160mm Magnifying power of a compound microscope is given by : m = L/fo[1 + d/fe] where L = Microscope length = 160mm, fo = Focal length of the objective = 8mm, d = Least distance of distinct vision = 25cm = 250mm
