Body: Often referred to as the head, the body is the upper part of a microscope including, eyepieces and objectives. Most compound microscopes are parcentered. Arm: Structural element that connects the head of the microscope to the base. All quality microscopes have achromatic, parcentered, parfocal lenses. It can also be used for photographic applications. Boom Stand (Universal Boom Stand): A microscope base that incorporates an adjustable arm or boom and enables the body to be aligned in a variety of different positions. Invented by a Dutch spectacle maker in the late 16th century, light microscopes use lenses and light to magnify images. It is used to vary the light that passes through the stage opening and helps to adjust both the contrast and resolution of a specimen. As a result, an improved color alignment is achieved although not as good as is achieved with plan or semi-plan objective lens. Nosepiece: This circular structure is where the different objective lenses are screwed in. Đồn CAKCN – Công an Việt Yên: làm rõ vụ trộm cắp tài sản trong KCN Song Khê- Nội Hoàng . Diaphragm or Iris: The diaphragm or iris is located under the stage and is an apparatus that can be adjusted to vary the intensity, and size, of the cone of light that is projected through the slide.
