‘Revolutionary’ Research Stereomicroscopes

Largest zoom range, 25:1 High-performance objective lenses Brighter, more uniform illumination

NIKON METROLOGY introduced two research stereomicroscopes for industrial applications, the SMZ25 and the SMZ18, that offer exceptionally large zoom range, high resolution, and bright epifluorescence. The extremely large zoom range and high resolution allow users to image a sample from its entirety down to its microscopic details.

Industrial fields including material research, crack-and-failure analysis, optics and electronics inspections, micro-manufactured assemblies, etc., have increasing needs for imaging systems that span large spatial scales, while maintaining the wide field of view, highest resolution, and fluorescence transmission.

The new Nikon stereomicroscopes incorporate the newly Perfect Zoom System that achieves a very high 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 allows researchers to image both the entire sample as well as its microscopic details using just a single instrument.

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

The new epifluorescence attachment employs a fly-eye-lens that enables brighter and more uniform illumination across the entire field of view, even at low-magnification range.  In addition, the signal-to-noise ratio has been improved by incorporating a short wavelength, high-transmission lens in the zoom body.  The result is clear, high-contrast fluorescent imaging.

A 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 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 visualize critical information such as magnification and diascopic illumination intensity on the LCD monitor and also configure camera acquisition settings using the touch panel.

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) 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 lets the researcher change focus, zoom, and intensity of the diascopic LED light with ease, and can also be used to capture images.
