Your Insight into the Technology Behind It Greenough Stereoscopic Design The basic idea behind a stereoscopic microscope is simple. It was formulated in 1896 by the biologist Horatio S. Greenough, who wanted to see small biologic samples magnified, but with the same quality as with unaided eyes. In other words, in three dimensions and with all the depth information he needed to understand the irregular shape of his specimen intuitively. He reckoned you could build a microscope with two separate beam paths facing the object from two directions, exactly as human eyes do when observing a small object...

Your Insight into the Technology Behind It Producing microscopes with pre-calculated optical a larger number of lenses and optical glasses with First apochromatic microscope objective, color characteristics based on Abbe's calculation was special dispersive properties were needed. Only corrected for three wavelengths based on the already a huge step for ZEISS. But, especially with the development of new optical glasses calculations of Ernst Abbe. working with large apertures, Abbe recognized by Otto Schott, the production of apochromatic The foundation for this achievement was in aberrations...

Your Insight into the Technology Behind It White LEDs Replace Halogen Light for Microscopy Lighting LEDs – light emitting diodes – are semiconductor white LED light contrasts your objects in a gentle diodes that emit visible light when a forward way. Since LEDs rarely ever fail, their lifetime is electric current is applied. The color of the light defined by “lumen maintenance”, which is the is nearly monochromatic and determined by the operating time until the initial light output has semiconductor material. To produce white light, degraded to 70 %. At ZEISS we specify 25,000 blue LED chips...

Expand Your Possibilities Stand M – Generous Sample Space. Large Focusing Range. Including Illumination. Stemi 508 is a high quality stereo microscope that's equal to the most demanding tasks in laboratory work as well as industrial failure analysis. A sophisticated microscope needs a coequal stand: Stand M offers generous specimen space and a large focusing column. On the other hand, Stand M is compact enough to be used in small lab rooms, all the more, since LED electronics are integrated and thus no external light sources necessary. Stand M LED controls up to two reflected light LED illuminators...

Expand Your Possibilities Stand K – Compact. Easy to Use. All-in-One. Workspace is limited in your lab or quality department? Do you usually stow away your systems and set them up again? Or you often work with untrained or multiple users? – In all these ways, the stand K line is made for you. With its small footprint and integrated LED illumination, a K stand turns your Stemi 508 into a compact all-in-one device that's easy-to-use and quick to pack up and reinstall wherever it's needed. To ensure the integrated LED illumination is optimized to your application range, choose from different stand...

Expand Your Possibilities LED Illuminators K/M - Bright. Longlife. Changeable at Your Choice. › Service Click here to view this video Click here to view this video LED spot illuminator – Change angle and height of the spot and zoom it – to create distinct shadows for a strong 3D impression. In the lowest position it delivers a grazing light that enhances fine structures on flat surfaces. Double Spot K LED – For sample preparations in reflected light, the double spot illumination with self-carrying goosenecks is optimal. It creates half-shadow effects that lead to a good 3D impression. During...

Expand Your Possibilities Boom Stands – Stable. Flexible. With Large Operating Range. There are various types of three-dimensional objects in stereo microscopy, and the applications are yet more diverse: customers often ask for different object details, even when looking at the same specimen. Your objects may be much larger than the footprint of any desktop stand. Or you may have to investigate small specimens in a very large area of interest. Or you may be sharing your Stemi 508 with several colleagues and need to swing your microscope between their workplaces. You could be, for example, a veteri­...

Expand Your Possibilities Fiberoptic illuminators - Brightest Light. Special Contrasts. Highly Optimized. You might have to distinguish fine details of dark colored specimen, or to evenly illuminate surface structures of large flat objects. You might want to look inside deep holes, or to get rid of annoying hotspots when imaging your glary specimen! Whenever your application demands higher brightness or better contrasts, decide for fiberoptic lighting! Powerful external lightsources in combination with compact, highly specialized fiberoptic illuminators solve even most difficult illuminations...
