    Overview

    Working distance is the vertical distance from the sample or where used the cover slip on top of the sample to the front lens of the objective (see diagram to the right).

    Hotstages require long working distance lenses because the sample is isolated from the lens by the hotstage chamber. In order to view samples in focus on a temperature controlled stage you need objective lenses with a working distance of at least 4.5mm.

    LMPLAN FL N - Long Working Distance Plan Semi Apo-chromat

    This is a Long Working Distance Plan Semi-Apochromat objective lens series with chromatic aberration corrected at a high level. A long working distance to a specimen in this series is effective for preventing the lens from interfering with a step or protrusion on the specimen.

    All of the lenses below are ideal for use with Linkam stages (except 100X which requires a special lid and cooling jacket)

    Objective Lens Magnification NA WD(mm)
    LMPLFLN 5X 0.13 22.5
    LMPLFLN 10x 0.25 21.0
    LMPLFLN 20x 0.4 12.0
    LMPLFLN 50x 0.5 10.6
    LMPLFLN 100x 0.8 3.4

    Nikon

    These Nikon objective lenses all have sufficient working distance to work with all of Linkam's heating and cooling stages.

    LD Epiplan

    Universal objectives for materials microscopy allowing brightfield, differential interference contrast and polarization methods. HD versions provide darkfield capability in addition. They feature special long working distances needed for materials inspections.

    Objective Lens Magnification NA WD(mm)
    Objective LD "Epiplan" 20x/0.40 0.4 7.3
    Objective LD "Epiplan" 50x/0.50 0.5 7.0

    EC Epiplan-Neofluar

    This is a series of objectives for the examination of materials. They differ from "Epiplan" objectives by their higher NA and, accordingly, higher resolving power and like all EC objectives they are optimized for highest contrast.

    Objective Lens Magnification NA WD(mm)
    EC "Epiplan-Neofluar" 10x/0.25 Pol M27 0.25 9.3
    LD EC "Epiplan-Neofluar" 20x/0.22 DIC M27 0.22 12.1
    LD EC "Epiplan-Neofluar" 50x/0.55 DIC M27 0.55 9.1

    Leica

    These lenses all have sufficient working distance for use with all Linkam stages.
