Stereo-microscopes owe their popularity to their wide range and ease of use. They are recommended for technicians, (coin) restorers and biologists. Since you don't need to prepare slides, you can even examine a whole beetle under them. The view is always almost breathtakingly three-dimensional.
Our SM-450T microscope is equipped with a 0.7x-4.5x zoom objective, which allows stepless adjustment of magnifications from 7x to 45x with the standard WF10x eyepiece. The eyepiece has an outstandingly large field of view: at 7x magnification, it gives a field of view of 28.6 mm. Thanks to its complex construction, it provides a contrasty image that is sharp right to the edge of the field of view. The trinocular microscope head can be slid up and down on a rod, and can even be turned sideways on request, allowing objects of virtually any size to be placed underneath (the stage provides a sharp image of objects up to 140 mm in size). The viewfinder has a 23.2 mm camera connection and a separate focus adjustment option, and can be switched to either the camera or the left eyepiece. There is 100 mm of space under the objective for work, which can be increased to 165 mm with an optional 0.5x reduction lens.
The microscope does not have built-in illumination, but can be retrofitted with external halogen fluorescent tube-ring illumination or LED illumination. By fitting the rubber eye cap included in the package to the upper part of the eyepieces, side scattered light can be excluded, making observations more comfortable.
The binocular head is tilted at 45° and its eye relief is freely adjustable between 55-75 mm. Dioptric correction is provided on both sides. The basic package also includes a sturdy covering foil to protect the microscope from dust when not in use.
In the series of images above, you can observe the details of the crown above the coat of arms on a 10,000 Ft paper coin through 0.5x, 1x, 2x, 3x, 4x objectives. The images were taken with a 2 megapixel camera.
