Stereoscopic Zoom Microscopes
An easy-to-use design that lets you concentrate on observation
6.3X zoom ratio offers
magnifications from 0.8X to 5X.
• By using twin zooming objective optics
developed exclusively by Nikon, the SMZ645 and
660 incorporate a convenient 6.3X zoom ratio,
enabling observations at just the right
A long working distance of 115mm (4.5 in.)
• The SMZ645 and 660 provide the longest
working distances of any microscopes in their
Streamlined base allows operation without
removing your hands from the microscope.
• The plain stand features a trim design that
makes handling samples much easier. Moreover,
the base has a wide front and smooth curves,
allowing operators to work while resting their
arms in a natural position.
New ergonomic auxiliary objective for
correct eye-level positioning
• Nikon has also developed a new G-AL ERG
ergonomic auxiliary objective that can be freely
adjusted to match the operator's eye-level for
comfortable viewing.
