Research grade stereomicroscope with apochromatic optics.
It is designed for observing three-dimensional objects and the details of their structure while maintaining the virtual volume and clarity of the surface relief. It is also equipped with a built-in transmitted light illuminator for examining transparent objects in brightfield. The installation of additional accessories will enable darkfield, fluorescence, and polarization methods.
The CMO (Common Main Objective) system provides a large field of view, high resolution, accurate color reproduction, and no field distortion. It produces an equally detailed and clear image in the eyepieces as well as on a digital camera. The CMO design involves installing additional components in the optical system.
The microscope is used for forensic examination, industrial inspection, biology, medicine (including IVF), microelectronics, materials science, and archaeology.

Microscope head

Trinocular head with an inclination angle of 20° that is comfortable for long periods of work. Eyepiece tubes rotate 180°. The user can adjust eye relief on the eyepiece to fit their height. The digital camera is mounted in the trinocular tube. Beam splitting 100/0 and 0/100. Diopter adjustment is done on the eyepieces.

Main objective

To form a three-dimensional image, the CMO stereo microscope uses a main objective, positioned strictly perpendicular to the sample plane. Light that passes through or that is reflected from the sample enters the objective and is distributed into two parallel optical channels. The stereoscopic angle is 11°.
The microscope is equipped with a 1x plan apochromatic objective with a numerical aperture of 0.15. It provides high image clarity and brightness for any research method over the entire magnification range. Working distance: 60mm.


Zoom objective lens – a lens system of parallel optical channels – smoothly changes magnification by 18x without losing focus. The microscope delivers an upright (not inverted) three-dimensional image.

Focusing mechanism

The coaxial coarse and fine focusing knobs are on both sides. The focus adjustment is smooth and effortless.

Stage plates

The transparent plate ensures homogeneous illumination of the specimen and optimal light diffusion for observing transparent and translucent samples. The black-and-white plate is ideal for observing opaque samples against a contrasting background: The black side is for light-colored objects, and the white side is for dark-colored objects.

Light source

The microscope is equipped with a transmitted light LED illuminator (10W). It is bright enough to work not only in brightfield, but also in polarized light and darkfield. The LED has a lifespan of 50,000 hours.

Key features:

  • Zoom system for achieving smooth magnification without focus reduction; zoom ratio of 18:1
  • The plan apochromatic main objective with 1x magnification and 0.15 numerical aperture: The image at any magnification is bright, contrasty, and detailed
  • Advantages of the CMO system: wide field of view, high resolution, no distortion, equal image quality in the eyepieces and on a digital camera
  • Powerful 10W LED transmitted light illuminator, specifically for working in darkfield and polarized light; its service life is 50,000 hours
