Stereo Microscopes - Illumination

Leica Microsystems offers a broad spectrum of excellent LED illuminators for various incident light applications.

Selecting the right illuminator

In addition to the composition of the sample, the information to be gained is most critical for selecting the right illuminator. Depending on the application and task, one or the other illuminator may provide better results. The next section gives you an overview of the strengths and weaknesses of the individual illuminators.

Bright, uniform illumination

Ring light illuminators are best suited for bright, uniform illumination.

Leica LED3000 RL, Leica LED5000 RL

High-contrast illumination

High-contrast illumination is offered by spotlight illuminators with moveable goosenecks for high flexibility. Fixed multi-contrast illuminators provide the same results, but their design makes the illumination settings reproducible.

Spotlight illuminators: Leica LED3000 SLI, Leica LED5000 SLI
Multi-contrast illuminators: Leica LED3000 MCI, Leica LED5000 MCI

Coaxial illumination

With coaxial illumination, the beam of light is guided through the optics and reflected on the sample. This requires the sample to be smooth and reflective. Coaxial illumination can be used with routine as well as high-performance stereo microscopes.

Leica LED5000 CXI

Highly diffuse illumination

Shiny samples are often very difficult to document. Under or overexposed areas are acquired by the digital microscope cameras and cannot be further evaluated. To improve this problem, a special dome illuminator was developed with the Leica FlexDome™.

Leica LED5000 HDI

Nearly shadow-free illumination

Nearly shadow-free illumination is achieved using what is called the "near vertical illuminator." Here, 2 LED spotlights are very close to the optical axis and shine on the sample.
