When using
microscope filters or sliders with the microscope condenser, there are several locations the filters can be placed. Filters are often placed above the light source. For example, a blue or ground glass filter is often placed directly above the light, as shown in the image below.
Visit this page for more information on the types of filters and their uses.
Often microscopes have built-in filter holders located above the light source that can be swung into place above the light or moved out of the way when not in use. The image below shows built-in filter holders that swing out of place.

Other microscopes will have a filter holder that slides directly into the condenser. The image below of the
biological microscope shows where the filter can be placed in the slider for insertion in the condenser. Additionally, this filter slider can be removed and a
darkfield slider or a
phase contrast slider can be inserted in this condenser.
