Nikon Metrology’s SMZ745 series - A superior model in this category

Featuring a high zoom magnification range of 7.5: 1 and a super long working distance of 115mm, the SMZ745 and SMZ745T stereo microscopes are both well suited for materials research and production line applications. The design incorporates a totally new reflection prism design, producing brighter images with stronger contrast. Anti-mould protection allows the microscope to be used in environments where ambient temperature and humidity are very high.

The SMZ-745T is the trinocular model equipped with a built-in 0.55x magnification C-mount camera adapter, permitting direct mounting of the Nikon Metrology’s Digital Sight camera series, most notably the Digital Sight 1000 model. This camera can operate without a PC and will even capture images directly onto an inserted SD memory card and display the image via its own HDMI output connector.

Product overview

There is a huge range of applications for these versatile microscopes throughout materials science and industrial tasks. They may be used as a desktop instrument or integrated into wire bonder pull tester machines. Production quality control functions are fulfilled for both routine or critical applications. The SMZ745 and SMZ745T are also ideal for failure analysis to determine and predict modes of failure as well as to verify solutions. Component surface examination, crack detection and corrosion studies are all carried out with ease, as is the investigation of composite materials, textiles and measurement of parts produced by machine tools, from critical aerospace components to building and construction goods.

Optoelectronic devices, microelectronics and micro-electro mechanical systems (MEMS) used in remote sensing devices such as accelerometers in  smartphones, gyroscopes are all prime candidates for inspection with an SMZ745 or SMZ745T. The product and accessories are well matched to verify the integrity of medical devices including implants, prosthetics, and intravascular systems. Other applications are to be found in modern paint and coating technologies, as well as the research, restoration and conservation of art works and antiquities.

Benefits and Features

nikon metrology industrial microscopes smz745 trinocular optical headTrinocular optical head

The optical head of the SMZ745T version allows for both stereo viewing and digital imaging. This is possible due to the built in camera port, complete with a C-mount 0.55x magnification adapter. It permits direct mounting of any Nikon Digital Sight Series digital camera and simplifies the process of digital imaging, image capture and observation via a monitor.
An optical path switch lever enables an easy changeover between eyepiece and camera.

A well-matched digital camera model for the SMZ745T is the Digital Sight 1000, as it can work completely in a stand-alone or PC free mode with a built-in SD card slot ,for image capture, and a HDMI connector allows a direct image display.


nikon metrology industrial microscopes smz745 zoom magnification7.5 : 1 zoom magnification ratio

The zoom range permits a lower magnification which is convenient for the selection of a region of interest, after which it is then easy to zoom in significantly to study key features at a 7.5 times greater magnification.

By optimising the design of the Greenough optical system used in the SMZ745 series, Nikon Metrology has been able to realise this large zoom ratio and so provide a total magnification range capability from 3.35x to 300x. Operator and inspection process time are both saved by having a full and modular program of flexible accessories.

Strong build quality and special surface treatments are features of the SMZ745 and SMZ745T. Both have an effective electrostatic discharge (ESD) protective coating to prevent samples and assemblies from being damaged by an electrostatic discharge current.  An anti-mould coating incorporated onto the interior components of the microscope allowing it to be used in environments where the temperature and humidity are exceptionally high.

The SMZ 745 & SMZ 745T have a streamlined shape for enabling maximum ergonomic advantages to be realised by the user. The zooming knob is equipped with a click stop option for each magnification step in the zoom range, and the optical switching lever for the camera port makes the digital imaging process even easier than ever before.

NIS Elements manages Nikon Digital Sight cameras to capture the best images for processing, organising the images and process versions logically in a smooth workflow. Fast, powerful image tools are enabled, such as:

  • mosaic creation from multiple images of a surface, e.g. following a long microcrack from start to finish
  • extended depth of focus (EDF) ,where an enhanced depth of focus view is provided as an image stack, or a single image is formed only from points of sharp focus.

The upgradable concept balances the software modules and capabilities purchased with a user’s needs satisfied.
