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.
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.
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.
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™.
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.

Benefits of LEDs
LED technology offers a great many advantages that are also of tremendous benefit in microscopy.
- Durability (25,000 to 50,000 hours, depending on the model)
- A natural color temperature
- Low power consumption (compared to halogen lamps)
- The illuminator can have a very compact design
- Usually operated without a fan (no noise)
- Constant color temperature, even when dimming
- "Cold light"
