    Description

    Objective LD Epiplan 20x/0.40 (D=0mm with or D=1.5mm without coverglass cap) (WD=7.2mm at D=0mm)

    Full Description

    Objective with removable, 1.5 mm cover slip cap. Without cover slip cap, the objective is suitable for the use of heating chambers or similar devices with an opening thickness of 1.5 mm. Without cover slip cap the working distance is 9.1 mm.

    To remove the cover glass cap please unscrew the green colour ring of the objective which can then be screwed on again without the cover glass cap.
