The Meiji Techno EMZ -5 Stereo microscope range is packed full of useful features 

Modular Flexibility 


The EM series microscopes are the most rugged microscopes from Japan and tailored to fit the needs of each and every customer. Modular design enables the user to engineer their own custom solution for virtually any application, selecting components from the widest range of bodies, stands, eyepieces, supplementary lenses, illuminators, camera adapters, and accessory components available in the microscope industry today

Superb Optics


The EMZ series microscopes feature multi-coated optical components, free from chromatic and spherical aberration. This provides  crystal-clear, high resolution images. The Greenough optical design provides superior erect, unreversed, stereoscopic images, rich in contrast, brightness and in their original colours. Excellent depth of field and a flat image rendition are also characteristic of the EM Series microscopes

Rugged Dependability 


All-metal aluminium alloy microscope bodies and components with chemical resistant finishes guarantee stability and rugged dependability for a lifetime of day-in and day-out use. Superior craftsmanship, quality components and materials result in long-lasting, high-performance products.

Ergonomic Design  


All EMZ series microscope bodies feature a compact lightweight design. Every stereo body features adjustable diopter tubes and interpupillary distance. Observation tubes are inclined at 45°, 60° or 90° for convenient fatigue free viewing depending on the application. A range of fixed of tilting focus blocks are available to mount the microscope body onto existing O.E.M. equipment. A choice of Zoom, Turret or Fixed magnification bodies with various working distances, optional auxiliary objectives and eyepieces, multiple adjustable stands, versatile illumination systems, and auxiliary components allow the end user to design a system to fulfil their specific requirements.

  • The ‘end’ arbour’ can be tilted to the desired angle and locked into position.
  • The articulated boom arm can be extended, turned and height adjusted to the desired length and clamped
  • The  articulated arm and articulated arm support assembly can be moved up the vertical pillar to the desired height and locked into position
  • The height locking collar is clamped into position under the boom arm support assembly to prevent any downward movement
  • The microscope/lens can be focussed using the focus knob on the microscope holder.
  • Optional ringlights or gooseneck illuminators can be added.

Optional End Arbours

An ‘End Arbour’ is a high grade steel pole onto which microscope holders (also known as focussing rings) and other devices can be attached.  They are hinged at the top with a clamp so the angle of the arbour and therefore the attached holder can be adjusted.  At the bottom the have a knurled cap which screws into the end, it is removed so that holders can be slid onto the arbour and it is then replaced to prevent any possibility of the holder from sliding off.  At the top they have an ‘E-Arm’ which is a special 5/8th inch diameter spigot (with a recessed clamping section).  This inserts into the end of the Boom Arm (or Articulated Arm) and is firmly clamped into place.  End arbours are available in different diameters, the most common is 25mm and this must match the hole in the microscope holder.

  • AV60-25   25mm diameter
