Swift and accurate identification of ultra fine structures, defects, scratches
or dust particles in incident light demands a high-performance stereomicroscope,
trained eyes and top quality illumination. At the SMT (Systems Integration in
Microelectronics) fair in Nuremberg, Leica
Microsystems is presenting its innovative LED illumination modules for stereomicroscopes,
which offer optimum illumination even for difficult material samples. Thanks
to modern LED technology, operating costs are significantly lower than for conventional
With its practically vertical illumination light path, the Leica LED3000 NVI
solves even challenging illumination applications such as samples with indentations
and drill holes not accessible using standard lighting components. The Leica
LED5000 CXI (coaxial illumination) provides excellent detailed illumination
of flat, highly reflecting surfaces such as wafers or polished metal samples,
and substantially enhances contrast. Both illumination modules can be optimally
combined with Leica stereomicroscopes for routine applications.
Extremely bright and homogenous illumination of the sample is offered by the
Leica LED5000 RL ring light, an all-purpose solution for different types of
applications. Due to conveniently switchable segments, extra information can
be obtained from the sample without having to move it. The multi-contrast illumination
Leica LED5000 MCI creates particularly high contrast on the sample: Due to the
flat angle of the oblique incident light, the finest irregularities and defects
such as scratches and dust particles are visualized. The ring light and the
multi-contrast module are ideal illumination modules for high-end Leica stereomicroscopes,
although the new LED modules can be used on most of the older models of the
Leica M and MZ stereomicroscope series as well.
All the illumination settings of the Leica LED modules are reproducible. A
constant color temperature is maintained during dimming. The LED modules offer
ideal conditions for documenting results with a digital camera, either as still
or moving images.
With a lifetime of up to 50,000 hours there is no need for lamp change and
lamp failure is no longer an issue, either. Using up to 90 per cent less energy
than a 150-watt halogen lamp, the LEDs cut operating costs and make a valuable
contribution to the protection of the environment.
