Research Stereo Microscopes come in motorized, manual versions.

Press Release Summary:

Motorized SMZ25 and manual SMZ18 are intended for industrial tasks as well as bioscience and medical applications. Perfect Zoom System enables zoom range of 25:1 (0.63-15.17x) and numerical aperture of 0.156 for SMZ25 with 1x objective at highest zoom, allowing researchers to image both entire sample as well as its microscopic details using one instrument. Epi-fluorescence attachment employs fly-eye-lens that enables bright and uniform illumination across entire field of view.

Original Press Release:

Nikon Introduces New Research Stereo Microscopes SMZ25/SMZ18

Nikon Corporation (Makoto Kimura, President; Chiyoda-Ku, Tokyo,) is pleased to announce the introduction of its newest Research Stereo Microscopes SMZ25/SMZ18, featuring the largest zoom range*1, extremely high resolution and exceptionally bright Epi-fluorescenceh.

The SMZ25/SMZ18 is ideally suited for both industrial tasks as well as bioscience and medical applications.  The extremely large zoom range and high resolution allows users to image the sample from its entirety down to its microscopic details.

• Product information

Product name F Research Stereo Microscope SMZ25 / SMZ18

Available from June 3, 2013

• Background of Development

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, whilst maintaining the wide field of view, highest resolution and fluorescence transmission. With these demands in mind, Nikon has developed two new stereo microscopes, the motorized SMZ25 and manual SMZ18.  Both feature extremely high resolutions and exceptional fluorescence transmission capabilities.  SMZ25 also features the largest zoom range on the market*2.

• Key features

1. The largest zoom range*³ (25:1) 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.

Especially, 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 dish. 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. A breakthrough in Epi-fluorescence imaging: stunningly bright images and high contrast

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)*4 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 and zebrafish. 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. 

*5 The OCC stands for Oblique Coherent Contrast. The OCC method uses the slide diaphragmlocated near the position of the entrance pupil of anobjective to shield luminous flux and applies coherentlight to samples diagonally.This gives shades to colorless transparent samples so they can be observed with contrast.
