Research StereoMicroscopes

Nikon Metrology offers its , the SMZ25 and the SMZ18, featuring large zoom range, high resolution and bright epi-fluorescence. The SMZ25 and SMZ18 are designed for industrial applications. According to the company, the large zoom range and high resolution allows users to image the sample from its entirety down to its microscopic details.

"Industrial fields including material research, crack & 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," said a company spokesperson. "With these demands in mind, Nikon Metrology has developed two new stereomicroscopes, the motorized SMZ25 and manual SMZ18. Both feature high resolutions and exceptional fluorescence transmission capabilities."

According to the company, key features include:

• Large zoom range (25:1) and enhanced resolution. The Nikon StereoMicroscopes incorporate a newly developed zoom system (Perfect Zoom System). The Perfect Zoom System enables both a 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 a single instrument.

The SMZ25 features 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 high-performance objective lenses allow imaging of microscopic structures once considered too small to visualize on a stereo microscope, said the company.

• Enahanced epi-fluorescence imaging. The 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.
• Wide range of accessories. A wide variety of accessories such as illuminators, bases and stands are available to accommodate a 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 visualize critical information such as magnification and diascopic illumination intensity on the LCD monitor and also configure camera acquisition settings using the touch panel.
• More ease of use. The thinner LED diascopic illumination base increases the efficiency and ergonomics of sample manipulation and exchanging of samples. The base also features Nikon's built-in Oblique Coherent Contrast (OCC) illuminator that produces high-contrast images of transparent samples such as ITO film. The OCC method uses the slide diaphragm located near the position of the entrance pupil of an objective to shield luminous flux and applies coherent light to samples diagonally. This gives shades to colorless transparent samples so they can be observed with contrast. The SMZ25 also features a remote controller. The 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.
