ZEISS Stemi 508
Your Quality Stereo Microscope for Biological and Industrial Routine
ZEISS Stemi 508 is your quality stereo 
microscope with mechanics and optics 
designed for the heavy workloads of 
everyday lab work and industrial inspections.
With apochromatic optics, Stemi 508 
displays your samples exactly as they are: 
rich in detail, sharp in focus and free from 
distortion or color fringes. The large 8:1 
zoom lets you get an overview within a 
35 mm object field, then bring the detail 
up to 50× magnification with impressive 
stereoscopic image contrast. Interchange­
able optics for observing specimens up 
to 120 mm in size, makes Stemi 508 a 
top performer in its class. 
With its lower viewing angle of 35° Stemi 
508 offers better ergonomics than any 
other Greenough-type stereo microscope. 
Maintain a relaxed working posture even 
after hours of work. 
Created for Your Applications
• Study and dissect model organisms, such 
as zebrafish, in oblique transmitted light 
in your embryology lab.
• Isolate egg cells before fertilization 
at 120× magnification in your IVF Lab
• Observe, document and identify 
insects – for example to map biotopes.
• Inspect PCBs in true color using cold 
light source and shadowfree ringlight 
• Rotate a quarter ring LED segment to 
quickly inspect your workpiece for 
scratches or defects
• Grade diamonds with impressive 
image contrast and no color fringes
• Assess the surface quality of paper or en­
gravings under grazing light with line light S
• Examine large workpieces, such as motor 
parts, using ball bearing stand SDA

Special Features:
• All Stemi 508 optical components 
are anti-fungus treated.
• Comes complete with changeable dust 
protection glass in front of zoom optics.
Choose the Best Illumination:
Reflected Light
• Double arm gooseneck – enhanced
contrast of 3D shaped objects through 
distinct shadow effects.
• Ringlights – shadow-free illumination
with less stereo effect, e.g. inspect 
printed circuit boards.
• Ringlights and polarization – stunning 
color contrast by reducing glare.
• Line light – grazing light for flat 
structured surfaces.
• Vertical light – illuminating sample 
crevices.
• Diffusor – giving soft light to observe
glary or shining objects.
• Area light – combining soft light 
and shadow effect.

Transmitted Light
• Bright-field – Look at colored objects 
• Dark-field – See object structures 
bright against a dark background 
• Oblique – Observe uncolored 
transparent objects in relief contrast 
• Polarization – study birefringent objects, 
detect stress in glass or plastics
