Nikon’s Stereo microscopes, SMZ25 and SMZ 18 are revolutionizing stereomicroscopy. With the world’s largest stereo microscope zoom range of  25:1, the SMZ 25, offers exceptional and unique capability. Parfocal ultra-high-performance objective lenses, exceptional optical design throughout and, accessory modularity all provide greater user convenience due to a design philosophy focusing on ergonomics

These new top of the range stereo microscopes cover a wide range of applications from routine stereoscopic observations with an image capture of superb quality, to more challenging applications where low magnification is used to select a region of interest, and then with the world’s highest zoom range available, a feature may be seen at a far higher magnification without the need for changing lenses or moving the focus drive risking a loss of position of the point of interest.

Once an objective turret is added the magnification can be extended far above the 25:1 presenting a high-resolution image to the operator equally to both the left and right side optical paths.

Innovative Nikon Optical Design

The innovative Nikon optical design system named  “Perfect Zoom Optics” realizes the world’s first and only zoom ratio of 25:1.

Even with a standard 1x objective lens, the SMZ25 captures the entire diameter of a  35mm dish and with only a zoom change delivers microscopic details at 25 times higher magnification.
By using the optional lens turret, multiple and parfocal lenses (all matched to the same object plane) may be used allowing a 0.5x lens to be used alongside a 2x lens so in combination with the 25:1 zoom provides a remarkable total magnification range capability. This is possible without disturbing the sample’s position or eyepiece height for the operator’s maximum comfort and efficiency in use.
