    Condenser Lenses

    Vendor: Linkam
    Part Number: LINK_COND-LENS


    The following information is for upright microscopes only. Inverted microscopes do not require a condenser extension lens.

    In order to set up the optimum illumination of your sample when working with transmitted light, (kohler illumination) you will need a longer working distance top lens for your condenser.

    Just as objective lenses have a working distance, so to do condenser lenses. The objective working distance is defined as the distance from the tip of the objective lens to the point at which the sample is in focus. In the diagram above this distance must be at least 4.5mm.

    The condenser working distance is the distance between the surface of the condenser lens and the point at which light from the base of the microscope is focused to a point. In the diagram above this must be at least 12.5mm.

    In a hotstage the sample is isolated from the objective and condenser by the hotstage chamber and so long working distance lenses are required.

    Long working distance objective lenses can be purchased from the microscope manufacturer or we can supply them for you. Linkam makes condenser extension lenses specifically for a variety of condensers.


    Select the specific condenser lens that matches your condenser type. If you have a phase contrast condenser you can add the phase rings specific to the lenses you will be using.
