WebA condenser microscope is one that illuminates specimen samples from beneath, shining light through it and into the objective lens for viewing. The condenser itself is a focusing lens that sits between the light source and the underside of the sample, and it acts to focus this diffused light to illuminate the sample so it can be viewed clearly ... WebA simple two-lens Abbe condenser is illustrated in Figure 1. In this figure, light from the microscope illumination source passes through the condenser aperture diaphragm, located at the base of the condenser, and is concentrated by internal lens elements, which then project light through the specimen in parallel bundles from every azimuth.The size and …
