The Zeiss Stereo is a stereo microscope product line. The Zeiss Stereo is used to observe large samples and inspect rough material surfaces. The Zeiss SteREO Discovery.V20 is a modular stereo microscope with motorized 20x zoom.[1][2]
What it is
Zeiss stereo microscopes generate three-dimensional, laterally precise images and are used to observe large samples and to inspect rough material surfaces. Zeiss stereo microscopes can be upgraded flexibly with different digital cameras and benefit from various types of illumination techniques. The SteREO Discovery.V8 is the entry-level model in the sophisticated stereomicroscope class from Carl Zeiss, developed for enhanced resolution, increased contrast, and an improved stereoscopic impression. The SteREO Discovery.V8 offers an 8:1 zoom range.[1][5]
How it works
The SteREO Discovery.V8 uses a zoom body parfocally harmonized for needle-sharp images over the entire magnification range from 1x to 8x. The instrument accepts three ranges of objectives: Achromat S for high-contrast images, Plan S for flat, distortion-free object fields, and PlanApo S for precisely detailed resolution with no color fringes. Illumination is provided by the fiber-optic CL 1500 ECO cold light source and by the VisiLED system of white LED illuminators controlled by the MC1500 multicontroller. The MC1500 multicontroller allows control of reflected, transmitted, and blended light, and up to 4 illumination settings can be stored and reproduced.[5]
The SteREO Discovery.V20 is a modular stereo microscope with a motorized zoom body offering a 20:1 zoom range. With eZoom, stepping motors position the movable lenses precisely, replacing the mechanical zoom curve with an electronic one. The V20 is operated through the SYCOP touch panel, which controls magnification, focus, contrast, and brightness. The V20 supports up to 345x total magnification and up to 1000 LP/mm maximum resolution.[2]
Where it fits in the process flow
Applications
Applications of the SteREO Discovery.V8 include wafer structure examination under darkfield reflected light and PCB component inspection under reflected light darkfield. The V8 supports oblique illumination in brightfield transmitted light and darkfield reflected light for surface-contrast imaging. The SteREO Discovery.V20 is applied to PCB component inspection with reflected light darkfield.[5][2]

Frequently asked questions
What is the zoom range of the Zeiss SteREO Discovery.V8?
The SteREO Discovery.V8 has a zoom range of 8:1.[5]
What is the maximum total magnification of the SteREO Discovery.V20?
The SteREO Discovery.V20 achieves up to 345x total magnification.[2]
What types of illumination are available for the SteREO Discovery.V8?
The SteREO Discovery.V8 supports cold light sources (CL 1500 ECO) and white LED illumination (VisiLED system), including reflected, transmitted, and blended light control.[5]
What is the maximum resolution of the SteREO Discovery.V20?
