For the traditional company A.KRÜSS Optronic, top quality with a good price-performance ratio is a goal it has set itself. Our gemstone microscopes are all high quality stereo microscopes and have been specially designed for the needs of gemmologists. Equipped with special accessories, they are ideal for the precise examination of minerals or for testing diamonds and colored stones. We offer different devices: in addition to vertical installation, horizontal devices or microscopes with swivel arms can also be purchased. In addition, there is the option of converting our existing microscopes with microscope cameras to modern digital microscope systems. In addition to the usual microscope components, many of our devices also have stone and cuvette holders as well as polarization filters. In addition, variable lighting devices are possible; these types of lighting include light and dark field microscopy and microscopy with incident light. A.KRÜSS trusts in its devices and demonstrates this with the 5-year warranty on housing, optics and mechanics!
