The Leica MS5, MZ6, MZ75, MZ95, MZ125, MZ16 and MZ16 A stereomicroscopes are optical instruments which use magnification for improved 
visualization of objects, their details and specimens from technology and 
natural sciences. The basic outfit, which includes a stand and a light 
source, can be supplemented with various modules for photography, TV, 
dual station viewing and other applications.
• The use of the instrument in a different manner from that described in
this user manual can lead to injury, malfunction and damage.

products can be modified or we could recommend other accessories 
for use in clean rooms.
