Nikon Metrology has launched its latest Research StereoMicroscopes, the SMZ25 and the SMZ18, featuring the largest zoom range1, extremely high resolution and exceptionally bright Epi-fluorescence. The SMZ25 and SMZ18 are ideally suited for industrial applications. The extremely large zoom range and high resolution allow users to image the sample from its entirety down to its microscopic details.
1. Large Zoom Range and Exceptional Resolution

The new Nikon stereo microscopes incorporate a newly developed zoom system (Perfect Zoom System). The Perfect Zoom System is a breakthrough in stereo microscope design, enabling both an incredible zoom range of 25:1 (0.63-15.17x) and a high numerical aperture of 0.156 (for SMZ25, 1x Objective, at the highest zoom), which allow researchers to image both the entire sample as well as its microscopic details using just a single instrument.

Specifically, the SMZ25 boasts a 35mm field of view at the lowest magnification of 0.63x (using 1x objective, 10 x eyepieces), enabling users to image the entire 35mm sample. At the high magnification range, Nikon’s newly developed high performance objective lenses allow imaging of microscopic structures once considered too small to visualize on a stereo microscope.

2. Breakthrough in Epi-Fluorescence Imaging
The new epi-fluorescence attachment employs a fly-eye-lens that enables brighter and more uniform illumination across the entire field of view even at the low magnification range. In addition, the signal-to-noise ratio has been improved by the incorporation of a short wavelength, high transmission lens in the zoom body. The result is clear, high contrast fluorescent imaging.
3. Wide Range of Accessories
A wide variety of accessories such as illuminators, bases and stands are available to accommodate the wide-range of research needs in the biomedical and industrial fields.

Nikon’s imaging software,  NIS-Elements (sold separately), can be now be used to operate the SMZ25 to capture multi-channel, time-lapse images, and Extended Depth of Focus (EDF) images. By combining the SMZ25 or SMZ18 with Nikon’s stand alone control unit DS-L3 (sold separately), researchers can easily visualize critical information such as magnification and diascopic illumination intensity on the LCD monitor and also configure camera acquisition settings using the touch panel.

4. More Ease of Use
The thinner LED diascopic illumination base increases the efficiency and ergonomics of sample manipulation and exchanging of samples. The new base also features Nikon's unique built -in OCC (Oblique Coherent Contrast)5 illuminator that produces high-contrast images of transparent samples such as ITO film.  The SMZ25 also boasts an easy-to-use remote controller. The new remote controller with focusing knob enables the researcher to change focus, zoom, and intensity of the diascopic LED light with ease, and can also be used to capture images.
