Basic ideas of Microscopy Microscopes represent the purpose of magnifying small objects. A microscope consists mainly of three components i.e. the objective, the tube and the eyepiece (see illustration ill 1.1). With a video microscope, the eyepiece is replaced by a high resolution CCD camera and the image is displayed on a monitor. For the viewing of objects, lighting systems are necessary. The illumination differentiates between incident light and transmitted light systems. The type of illumination is dependable on where the light falls on the object. With high magnification, the...

Basic ideas of Microscopy Objective: The demand for objectives applicable in the microscopy is very high. With large field image, the curvature of the field should be kept simultaneously as low as possible. The objectives used in the microscopy possess a norminal so-called parfocalizing length of 45 mm. This is the distance between the object plane and the attachment surface of the objective at the tube. ill.: 2.1 Attachment surface at tube Parfocalizing length Objective Object plane Free working distance between object and objective Parfocalizing length 45 mm Tube length: The mechanical...

Basic ideas of Microscopy Eyepieces: The eyepieces differentiate between two designs i.e. per Ramsden and per Huygens. The eyepiece per Huygens allows a lower magnification and has the advantage on spherical and chromatic aberrations. Ramsden eyepieces are essentially in application for the viewing of large object fields. Eyepieces with integrated graticules or scales allow a direct measuring of the objects during beaming. To correct visionary error a diopter compensation can be taken on the eyepiece. ill.: 3.1 Micrometer eyepiece per Huygens Diopter compensation: Focusing the graticule on...

Tube elements In order to possibly achieve large multiple variance, the microscope tube has been intersected to allow the essential accessories to be offered as elements. The user has therefore complete freedom of choice concerning tube length, deflection and beam-splitting. Three sizes are available: B30, B40 and B60. With bores and threads in fixed rasters, the elements can be connected to one another. Flange bushing provides for an exact and light-tight alignment of the centre bores. Threaded bores are located on minimum each one external surface for mounting the parts on raster plates...
