MZM 1 - The Mono-Zoom-Microscope

For a continous change in lower magnifications our MZM 1 with a zoom ratio of 5 offers widest opportunities in object fields and working distances. The mono-optical path is absolutely vertical adjusted.




Because of its large field of view and the compact construction the MZM 1 is useable in all sections of technical production, especially for highest quality control.

All advantages of this microscope are reached when object identification is necessary at once.

The MZM 1 is designed to be suitable for use either as a table top model or for fitting onto machines. Encouraged by a variaty of accessoires as illumination units, optional achromats and eyepieces as the possibility of photografic and video image documentation it ensures a perfect adjustment to meet the expected demands.

Microscopes with manual specimen positioning and image processing software

All microscopes possess an adapter for a CCD camera. Thus the equipment of every microscope with an image processing system is problem-free possible.

The image processing system makes the representation of the live-image for the camera possible on the PC monitor.

Optionally also the simultaneous visual observation is possible by auxiliary optics.

The image processing system can be equipped with most different cameras (analog cameras and digital megapixel cameras). The measuring software possesses different equipment degrees and prices. The entrance for an adequate measuring and documentation software begins with 400 EUR.


You can download a full version free of charge here and test 14 days >

Inspection and measuring workstation


For these workstations inspection tables with most different positioning ranges are available.

Different lighting can be used.

As imaging optics the entire pallet at technical microscopes (TM1, TM2, MZM1) is available.

In principle all equipment characteristics of the visual microscope types are available equally for the devices with BV system.


Gladly we are to you for a telephone consultation at the disposal.

Measuring microscopes with stepper motor controller, image processing system and motorized table

The OEG GmbH supplies complete motor controlled microscopes, particularly with customized equipment. The microscopes possess the following basic components


Microscope and/or telecentric measuring objective mounted at motor-driven z-axis

The microscope is adapted in its enlargement as well as regarding the assigned lighting to the item under test.


Cross table*


The cross table positions the sample and is adapted regarding measuring field to the specimen size. Further the assigned lighting must be considered. View in Incident and transmitted light are possible.


Stepper motor controller


The CONTROLLER possesses 3 axles (x/y for the cross table and z for the focus). For the interactive use it possesses a Joystick.


Image processing system with CCD camera (alternatively analogue or digital) and Frame Grabber (only for analogue cameras), PC with 19«-Monitor

The Frame Grabber digitizes the camera signal for the further processing in the PC. The Frame Grabber is steered by the software and is in a PCI Slot of the PC's. With the use of digital cameras is made the connection to the PC by USB 2.0.




The software controls the image processing system and the stepper motor controller. It possesses standard measuring functions. Special measuring functions can be supplied if necessary. The software is to be described in the following one more near.


*For simpler measuring tasks possibly different components are needed not or not in the described equipment. Then the system can be more simply developed.
