    What is a microscope ? A microscope is a high precision optical instrument that uses a lens or a combination of lenses to produce highly magnified images of small or lamps) to make it easier to see the subject matter. What is microscopy ? Microscopy is the use of a microscope or investigation by

    , Anton van Leeuwenhoek, is considered the father of microscopes because of the advances he made in microscope design and use. He worked as an apprentice in modern compound and stereo microscopes have changed very little. In the early 1930's the first electron beam microscopes were developed which

    are two main categories - (1) compound (high power microscopes), and (2) stereo or dissecting (low power microscopes). Compound Microscope This is the most common type of microscope. It can also be referred to as a biological or research microscope. The compound microscope is what many refer to as

    is both educational and important for medical and science applications. Stereo Microscope Stereo microscopes are the second most common type of microscope. They can also be referred to as dissecting, dissection, or inspection microscopes. The stereo microscope is what many refer to as a low power

    specimens up to 250,000x or more. Users can examine the topography of a specimen, its morphology, composition, etc. Digital - These are a combination of a microscope and a digital camera. The more common types are the digital cameras which can use a CCD or CMOS chip. The camera can be integrated

For stereo microscopes, they usually have one or two objectives lenses which normally are 1x, 2x, 3x, or 4x. In addition, there are zoom models which operate

    ) Since specimens rarely generate their own light, illumination is necessary. Illumination is the application of light onto an object or specimen in a microscope. The illuminator is the source of light which illuminates the object or specimen to be observed. Illumination of the object or specimen

    direct and intense illumination. These light sources can be from above the specimen or object which is used mainly with low power stereo microscopes and is called incident (reflected) light or from below a specimen (typically a slide specimen) which is light passing up through the specimen from

In a stereo microscope, a nosepiece can be referred to as a single objective ) - a long boom type stand used to support a microscope body. It has many adjustments allowing the microscope to be aligned in a wide variety of configurations

Plain Stage Mechanical Stage Stage Plate A stage plate is used with stereo microscopes and this plate fits in over the lower illumination in a circular hole. It normally is a frosted glass plate or a dual sided (white and black
