The 2054 series microscopes differ from the 2034 series in that they have an aluminium base and a modified focussing mechanism. Focussing is accomplished by moving the tube axially with a rack-and-pinion drive. The short light path through the microscope makes the object appear reversed. The optical system consists of a lens and an eye cup. All lenses are coated for sharp, high contrast images Seven types of lenses are available: 2x, 4x, 6x, 10x, 15x, 20x and 30x. The ocular has a magnification factor of 10x and the focal plane is equipped with a scale. Contamination of the scale with dust is not possible thanks to the Huygens design with focal plane in the lens system. The lens closest to the eye in the ocular can be moved by turning the adjustment ring, so that the scale can be adjusted to match the eye correction of the observer. The oculars associated with each magnification factor (object lens) can be replaced by simply pulling out. If additional lenses are to be used for visually checking purposes only, additional oculars are not required. The side illumination allows measurements on dark surfaces or in darkened rooms. Two 1.5 Volt AA batteries are required for operation. The microscope is supplied in a padded transport box offering secure transport space for four additional lenses available as accessories. Use of the MKH tripod gives the 2054 series microscopes greater stability. This is an essential accessory for reliably checking rollers.
