Generally this term is used in describing a high power (compound) microscope. Articulated arm microscope stands are often used in industrial and manufacturing settings.īase: The bottom support of the microscope (you may want to also see arm above).īinocular Head: A microscope head with two eyepiece lenses, one for each eye. The microscope body is held onto the articulated arm stand with a focusing holder. The stand clamps to a table or has a large base and has a variety of motion in three dimensions.

The polarizer is placed over the microscope light source.Īrticulated Arm: A type of microscope stand that holds a microscope body. On a stereo microscope the analyzer typically connects to the bottom of the stereo microscope body and on a compound microscope the analyzer fits in the head of the microscope. The result is a better (but not perfect) alignment of some of the colors at the focal point, thereby giving you a clearer image.Īnalyzer: A microscope analyzer is used with a polarizer to provide polarizing light. These lenses are made of different types of glass with different indexes of refraction. To help correct this problem, achromatic lenses are used.

Some colors will refract more than others and as a result, those colors focus at different points, reducing resolution. There are two types of condensers - one is a spiral type that you turn to move it up or down and the other is on a rack and pinion system and is controlled with a condenser focusing knob.Īchromatic Objective Lenses: When light goes through a prism or lens, it is bent or refracted. All of our microscopes that have 1000x magnification use Abbe condensers with a 1.25 N.A. The condenser lens system should have a numerical aperture equal to or greater than the N.A. Abbe condensers become more useful at magnifications above 400x. By changing the size of the iris and moving the lens toward or away from the stage, the diameter and focal point of the cone of light that goes through the specimen can be controlled. The abbe condenser has an iris type aperture to control the diameter of the light that enters the lens system. Below you will find many of the terms used in the 'Microscope World' - or just simply in microscopy.Ībbe Condenser: A specially designed lens that mounts under the stage and is usually movable in the vertical direction.
