Offers the highest zoom ratio thanks to Nikon’s Perfect Zoom System

A breakthrough in stereoscope design, Perfect Zoom System dynamically change the distance between the two optical axes as the zoom factor is changed. This change in optical axis distance enables maximization of light entry into the optical system at every magnification. The result is an uncompromised, large zoom range, high resolution in both eye paths, and minimal aberrations over the entire zoom-range. Furthermore, this breakthrough in optical design enables all of these desirable features be housed in a compact zoom body, resulting in an ergonomic instrument design.

Superior resolution never before seen on a stereomicroscope

Nikon SHR Plan APO series for SMZ25 / 18 stereomicroscopes

Nikon’s newly developed objective lens series, the SHR Plan Apo series, offers a high resolution of 1100LP/mm (Observed value, using SHR Plan Apo 2x at maximum zoom). The new SHR Plan Apo series of lenses deliver brilliant images with true-to-life colors.

Enhanced brightness and uniform illumination in low magnification range

Enhanced Brightness for SMZ25/SMZ18 stereomicroscopes

The SMZ25 series is the first stereo microscope in the world to use a fly-eye lens on an epi-fluorescence attachment. This innovative design ensures bright and uniform illumination even at low magnifications, resulting in uncompromised uniformity in brightness across a large field of view.

Improved S/N ratio and crystal clear fluorescent images thanks to an improved optical system

Crystal Clear Images with SMZ25 / SMZ 18 stereomicroscopes

Nikon’s newly developed optical system offers a drastic improvement in S/N ratio even at high magnifications. This improved S/N ratio makes it possible to capture cell division, which is difficult using conventional stereo microscopes, and samples with low excitation light.

Zoom body with significant improvements in optical performance

Nikon has succeeded in improving the signal and reducing noise in fluorescent images by using a short wavelength, high transmission lens. Combined with an innovative epi-fluorescence attachment, the SMZ18/25 is better able to detect excitation light than conventional fluorescent stereo microscopes.

A wide range of digital imaging capabilities with the DS series and NIS-Elements imaging software

Easily obtain the information you need, such as Z drive position, zoom factor, objective lens, filter cube, and LED DIA brightness by using the Digital Sight series and NIS-Elements or Digital Sight series DS-L3 together with the microscope.

Imaging Software NIS-Elements

One software for all systems: NIS-Elements which is Nikon’s flagship, cross-platform imaging software can now be used with Nikon’s latest stereomicroscope systems SMZ25 and SMZ18. NIS-Elements enables a wide range of advanced digital imaging capabilities, easily from a PC.

Multichannel (multicolor)

Multiple fluorescent channels can be captured in conjunction with other imaging methods such as OCC or brightfield.

Time lapse

Easily setup a time-lapse imaging experiment with NIS-Elements.

Extended depth of focus (EDF)

Capture multiple high resolution images at different focal depths to create a single extended depth of

focus image or quasi-3D image.

Digital Sight Series DS-L3 (optonal)

DS-L3 is an easy-to-use high-definition, large touch-panel monitor that can be used to quickly capture images without a PC or monitor. The scale bar automatically adjusts to accommodate changes in magnification. Optimal imaging parameters for each sample type and observation method can easily be set using the icons. For available combinations, please contact Nikon Metrology.

Easy-to-use OCC illumination

SMZ25  SMZ18

The new LED DIA Base with a built-in OCC illuminator generates minimal heat, consumes little power and is long-life. This illuminator can enhance the contrast of uneven surfaces.

Eas-to-use OCC illumination  for SMZ25 / SMZ 18 stereomicroscopes

The OCC illuminator can be controlled using a slide lever. Thanks to scales on the slide lever, the user can save and reproduce desired illumination levels. In addition, an OCC plate can be inserted into the illumination unit from the front and rear sides, so images with different shadow direction can be observed.

What is OCC illumination?
The acronym OCC stands for oblique coherent contrast (OCC), which is a form of oblique lighting method developed by Nikon. Compared to conventional diascopic illumination that illuminates directly from below, OCC illumination applies coherent light to samples in a diagonal direction, giving contrast to colorless and transparent sample structures.

User-friendly remote controller

SMZ25The all new remote controller provides easy access to zoom and focus controls and is designed for both right and left hand use. The remote controller contains an LCD monitor with an adjustable backlight which provides information regarding the zoom factor, objective lens, filter cube, and LED DIA brightness at a glance.

User Friendly  Remote Control SMZ25 stereomicroscope

On-axis imaging for digital images

Easily switch between stereo position (stereoscopic view) and mono position (on-axis view) when using the P2-RNI2 Intelligent Nosepiece by simply sliding the objective lens.
