Specimen stages and accessories

The specimen stage supports the specimens that are to be examined through the mi- croscope. Several options are available to accommodate the wide variety of specimens examined, such as object guides, extension plates, specimen clips, scanning stage, heating stage, etc.

Objective nosepiece and objectives

The objective nosepiece is used to hold the objectives. L objectives with long working distances, for example, are specially corrected to respect different thicknesses of vessel bases. All microscope objectives from magnification 2.5x to 100x can be used. All objectives from the DM L and DM R range with 25 mm thread are compatible. The performance data of Leica objectives can be found in the chapter “Technical Data; Performance Data” or on the relevant objective lists available from your Leica agency.

IR/R tube adapter

The tube adapter is used to adapt tubes from the DM R range.

Eyepieces

A magnified, virtual image of the actual intermediate image produced by the objective is produced with the eyepieces. They act as a magnifier.

Transmitted light illumination unit

The transmitted light illumination unit consists of the lamphousing and the transmitted light illumination column. The transmitted light lamphousing comprises a precentred 12 V 100 W halogen lamp and a filter module for three swing-in filters.

Field diaphragm

The field diaphragm is used to produce Koehler illumination.

Lamphousings

A variety of lamphousings are offered for the DM IRB (for halogen, mercury or xenon lamps). The description and area of application can be found in the operation section of this manual.

Filters

Filters are generally used to enhance the contrast of the specimen and are assembled in the illumination column. A variety of different filters are easily changed.
