World's largest zoom range and highest resolution in the SMZ series

Dynamic zoom ratio of 25:1

An innovative optical system known as Perfect Zoom System provides the world's first zoom ratio of 25:1 (zoom range: 0.63x - 15.75x). Even with a 1x objective lens, the SMZ25 captures the entire 35mm dish and simultaneously delivers microscopic details.

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

SHR Plan Apo series

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.

Auto Link Zoom (ALZ) supports seamless viewing at different scales

ALZ automatically adjusts the zoom factor to maintain the same field of view when switching objective lenses. This function enables seamless switching between whole organism imaging at low magnifications and detailed imaging at high magnifications.

Bright and high contrast fluorescent images

Enhanced brightness and uniform illumination in low magnification range

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

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.

Automation and digital imaging

A wide range of digital imaging capabilities with the Digital Sight 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.
