M50/M60/M80 – Routine stereo microscopes

Easily inspect, screen, observe or document. Handle your daily inspection or documentation, work confidently, and stay flexible in times of change. The modular stereo microscopes of the M series from Leica are the right choice for an abundant variety of tasks in life sciences and industrial applications.

The M50, M60, and M80 allow operators to see a large sample overview, work comfortably under the microscope, and capture images of important details easily.

At a glance

All three microscopes allow you to acquire comparable and traceable results at different magnification steps. This provides accuracy for repetitive tasks, for example in electronic inspections or screening of model organisms.

  • M50 with 5:1-zoom, featuring a step-zoom with five fixed zoom steps, at 6.3x, 10x, 16x, 25x, and 40x– allowing 100% reproducible results. The short optics carrier enables high light throughput and provides a large working distance, ideal in animal surgery and similar applications.
  • M60 with 6:1-zoom range, with a continuous zoom from 6.3x – 40x including engageable click stops – making repetitive inspection and measurement at a specific zoom position reliable. This system is optimized for a larger field of view to see more at a glance.
  • M80 with 8:1-zoom range, with a continuous zoom from 7.5x – 60x including engageable click stops – expanding your insights and reliability. Optimized for higher magnification to see smaller details in perfect contrast.

The right illumination determines what you see

Depending on

  • your sample
  • your application, and
  • your task,

illumination can make a major difference with regards to what you see or don’t see.

Simple is simply good

The M series stereo microscopes have been designed to provide tailored solutions for operators working in laboratories or in manufacturing.

Enjoy working with Leica optics that deliver outstanding resolution paired with great depth of field, so that you see all relevant structures at a glance.

You can easily change from sample overview to fine detail imaging. No refocusing is needed when changing magnification – parfocal optics allow you to keep your sample in focus at all zoom levels.

High flexibility with a modular concept

Whether your work requires a variety of illumination types, different objectives, or a bigger stand – Leica Microsystems has a solution for nearly everything!

Turn your microscope into a highly flexible and ergonomic workstation for multiple users. Our broad range of accessories helps you to cover all your needs:

  • Small, medium, and large incident light bases: Inspect e.g. printed circuit boards, metal workpieces, or opaque research samples like flies on a fly-pad
  • TL transmitted light bases: observe translucent samples or screen model organisms like zebrafish or look for defects in glass and silicone molds
  • XL universal base: accommodate large workpieces, our XL cross-stage has a travel paths of up to 300 mm x 300 mm
  • Swing arm and flex arm stands: Examine very bulky pieces, e.g. automotive parts or paintings, or adjust your viewing angle when dissecting, or pulling pipettes
  • Objectives: Choose from a variety of achromat and planachromat objectives depending on your requirements like working distance or FOV

Working efficiently with Ergo accessories

Every person is different – that’s why microscope workstations need to be adaptable, especially when they’re shared by multiple users. Ergonomic accessories help microscope operators to work comfortably even if they spend the entire day on the microscope.

With the Leica M series you can easily adapt your stereo microscopes to seamlessly fit multiple users.

  • Adjustable viewing heights ensure that shoulder and neck muscles are not strained.
  • ErgoTubes promote an upright sitting position by bridging the gap between the microscope and the users’ eyes. This is especially important for tall users.
  • ErgoModules bring the eyepieces of the microscope closer to the operator by inserting a wedge below the eyepieces. This promotes an upright posture, no matter how tall the microscope user is.
