Stereomicroscopes

Stereomicroscopes - special tools for industry, trade and research

The name stereo microscope comes from the special feature of these devices. These microscopes have two separate beam paths for the eyes of the observer. This adds a spatial effect, which is where these microscopes get their name addition stereo. Such stereo microscopes are especially useful when working on small objects. This is why there are numerous applications for this special type of microscope in industry, teaching, research and technology. They are used, for example, in the restoration of antique objects. Dental technology also uses stereo microscopes for the production of implants. As industrial microscopes, they are suitable for production and quality control of precision mechanical and electronic components.

Stereomicroscopes and their characteristics

The construction of stereo microscopes is comparable to that of classical microscopes. The system consists of an objective, an eyepiece and an object stage on which the object to be observed is placed. The objects on the stage can be illuminated with both incident light and transmitted light. In most models, the intensity of the illumination is adjustable. In this way, both solid objects and transparent, thin objects can be illuminated.

The lenses have a zoom function. This is infinitely variable and works at a ratio of 1:10. The zoom is between a factor of 0.6x and 8x, depending on the model. Various objectives and eyepieces are also available as accessories for the stereo microscopes. In this way, the field of view and the magnification can be individually adapted to the desired area of application. The wide-field eyepieces allow different fields of view with diameters between 12 and 22 mm.
The pupil distance is adjustable, usually in a range between 53 and 75 mm. This is an important feature in stereo microscopes with the two separate eyepieces. In this way, individual adjustment to the observer is possible and comfortable and ergonomic working is guaranteed.

Industrial microscopes - devices with special features

Industrial microscopes represent a separate category within stereomicroscopes. Their technical features are specially adapted for industrial use. These microscopes are particularly notable for their extreme magnification. Object magnifications of up to a factor of 500x are possible.

With an industrial microscope, both polarization and dark field observation are possible. The polarization filter is adjustable and offers the usual filters for yellow, green and blue as well as the option of frosted glass. In addition, the systems have interchangeable objectives. The industrial microscopes are compatible with bright and dark field objectives. These objectives are also available in different magnifications.
In addition, the industrial microscopes have particularly large object stages. The two-axis stages, for example, have sizes of 160x140 mm. An adjustment range of 35x30 mm is possible. Models with an extra large stage have stages with dimensions of up to 300x268 mm and an adjustment range of 250x200 mm.

Parallel light stereo microscopes give special illumination options

The parallel light stereo microscope is another special type in the category of stereo microscopes. These devices differ from the other microscopes because of the special arrangement of the illumination. They have both transmitted light and reflected light illumination. Ring and coaxial illuminators are available as accessories. Thus, for example, deep bores on objects can be illuminated with the coaxial illumination, which is not possible with other microscopes. The parallel light also prevents eye fatigue.

The illumination is realized with the aid of energy-saving LEDs. On the one hand, these enable bright illumination of the object in the desired manner. On the other hand, the LEDs are also infinitely dimmable. In this way, the brightness can always be adjusted to the required intensity. The Parallellicht stereo microscopes have separate controls for adjusting transmitted and reflected light illumination. An optional iris diaphragm can be inserted into the objective. This diaphragm is available as an accessory. An iris diaphragm reduces the visible light cone and thus reduces stray light.

In addition, so-called beam splitters can be used with parallel light stereomicroscopes. These divide the single light beam into two separate ones. Through this beam splitter, the excitation light emitted by the illumination is reflected in front of the object. The fluorescence light, on the other hand, passes through the divider unhindered. This significantly improves the quality of the images.

Cameras for stereo microscopes

Certain models are compatible with digital cameras. Corresponding camera systems are available as accessories. These can be connected directly to the stereomicroscope. With these cameras it is then possible to take pictures and videos of the objects.

The digital cameras for the stereo microscopes provide high-resolution images and videos with up to 1080p, which corresponds to a resolution of 1920x1080. Videos are also recorded by the cameras with this resolution and a frame rate of 30 fps. Brightness, contrast and gain can be adjusted via the camera's controls. In addition, the cameras have an automatic aperture selection and white balance. The camera stores the digital data on an internal memory. Connection to a computer system and data export are possible via a USB interface. Furthermore, the cameras are compatible with USB memory media and memory cards.

The digital camera with pad has an integrated monitor. This is also attached directly to the C-mount of the microscope. Thus, a direct control of the view is also possible via the display. This flat screen monitor has a screen diagonal of 11.6 inches (approx. 29 cm) and is therefore particularly compact. In addition, the systems also have an HDMI interface. Via this, it is possible to connect a larger display in order to obtain more detailed images if desired.

With the cameras for the parallel light stereo microscopes a direct connection to a pc is possible. Thus, the images and videos can be viewed directly on the computer. The corresponding software allows an immediate control of the data. Furthermore the software helps to measure the object. Geometric details such as lengths, angles or the distance between two points can be measured by the program with accuracies of up to +/- 0.01 mm. This data is then conveniently available on the PC for further processing.
