Metallographic Microscopes

The primary purpose of Microscopic Examination is to reveal details of metal structures, which are too small to be seen under the unaided eye. Metallurgical microscopes can be used to determine grain size, inclusions, previous heat treatment, possible causes for failures, deformation, and inter-granular corrosion. In short, Microscopic Examination can reveal a great deal about the past history of a metal specimen, and how it will act in service.

Metallurgical Microscopes

Metallurgical microscopes (also known as materials microscopes) are equipped with an incident light source (also called reflected) which sends the light through the objective onto the reflective surface of the metal. The sample has to be perfectly flat and is usually polished, a 'micro' specimen will normally have been prepared of the metal, composite, ceramic or polymer sample using equipment available within our Materialographic Division. This type of microscope can sometimes also be used to look at particles trapped on filters.

Stereo Microscopes

Stereo microscopes, also known as dissecting and low power microscopes, are used to examine any specimen that is not mounted on a slide (although many slide mounted specimens can be observed).

They are particularly useful for examining unprepared specimens that are not thin but are 'lumpy' such as metal parts, fractures, welds, mouldings, polymers, castings, bores, geological specimens, fossils, industrial parts, insects, plants, coins, archaeological artefacts, pond life, invertebrates, zoological specimens, embryos, forensic samples, textiles etc. We have the largest choice of stereo/dissecting microscopes in Europe.

You will find these different types of stereo microscopes in our range:

  • Single Magnification Stereo Microscopes - change magnification by changing objective cartridges and/or eyepieces (lowest cost microscopes)
  • Dual Magnification Stereo Microscopes - change magnification between two magnifications by rotating a turret
  • Zoom Magnification Stereo Microscopes - the most popular type of microscope where you change magnification using a zoom control knob. There are two types of stands available with most stereo microscopes:
    • Standard Bench Stands - the most common types of stands for all types of microscopes, often with built-in top & bottom lights
    • Long Reach Stereo Microscopes - highly popular in industry for observing larger specimens or where a large, clear work area is required Supplementary illumination such as fibre optic goosenecks or LED ringlights are often used with a stereo microscope

Polarising Microscopes

Polarising microscopes are used to observe the polarisation characteristics of materials. Typical specimens are geological, crystals, asbestos, fibres and polymers.

This type of microscope typically has an upper polariser (called an ‘Analyser’) in the head of the microscope and a lower polariser (called a ‘Polariser’) which is mounted beneath the specimen stage and above the illumination.

The polarisers are rotatable and are often positioned so that they are ‘crossed’ at 90 degrees to each other. With no specimen in place this will produce a black image (called extinction’). When a light diffracting specimen is placed on the stage , light is scattered producing an often beautifully coloured image where the colours are proportional to the diffractive characteristics of the specimen.

The specimen stage is always round to allow specimens to be rotated by specific degrees allowing the analysis of the materials under observation.

Our products include entry-level hobbyist microscopes, a great range of robust university teaching grade microscopes and top-end research microscopes. There are transmitted (bottom) light, incident (top) light and both dual illuminated versions available. More advanced models have waveplate inserts and Bertrand Lenses for additional analysis such as conoscopy.

Digital Microscopes

Digital microscopes can be loosely defined as microscopes with cameras built-in. Adding a camera to an existing microscope will also create a digital microscope. In this section we will display mainly with those microscopes with built in cameras.

There are various categories and levels of digital microscopes:

  • Microscopes with built-in USB cameras requiring a PC (or MAC) to see the live image
  • Microscopes with built-in HDMI, WiFi, video or SXGA cameras requiring connection direct to a monitor or Wifi connection to a smartphone or tablet to see the live image
  • Microscopes with built-in cameras and a display monitor on top, some of these include a tablet PC with touch screen controls

Cameras for Microscopes

Our range of cameras for microscopy provide high levels of functionality at excellent prices are have been specially designed for microscopy use. The most popular are our GXCAM family includes a range of useful accessories and a very comprehensive GXCAPTURE software package making them the most popular range of cameras we supply. Cameras can be connected via USB to your computer or can be connected direct to a display monitor and many of these have on-board SD card slots for computer-free image capture.


We are also able to offer all levels of software from basic image capture (usually free with the camera) to advanced automated image analysis for particle sizing and metallurgical analysis (eg grain size, inclusion counts, porosity etc).

Camera Adapters

Cameras can be connected to any microscope, we have a very wide range of camera adapters suitable for almost every type of microscope ever made. We have particular expertise in this field.

In all phases of microscopy, cleanliness is essential especially when it comes to optical parts. Lenses should be maintained free from fingerprints, dust and oil films. High quality lenses are usually coated with an extremely thin film to reduce light loss from reflection. Acid from a fingerprint can etch through the film and spoil the lens. Oil used with an oil immersion lens should be removed immediately after use and not allowed to dry on the lens.
