Selecting the Right Illuminator
Your choice of illumination determines what you see. Depending on the specimen, application and task, one illumination may be better than another. The following overview is intended to show which illumination you can use to achieve the best result.
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.
Diffuse Illumination
Shiny samples are often very difficult to document because they reflect light. Underexposed or overexposed areas are acquired by the digital microscope cameras and cannot be further evaluated, because there is no image information due to shadows or reflections. To solve this problem Leica Microsystems has developed diffuse illumination systems:
Leica LED5000 HDI and Leica LED3000 DI
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.
Leica LED3000 NVI and Leica LED5000 NVI
Transmitted Illumination
Transmitted illumination can be used to examine transparent samples quickly and easily. The large flat surface and the intuitive operating concept are suitable for simple tasks and ideally supplement existing incident illumination.
Leica LED3000 BLI
Available Models
Leica LED5000 NVI
The Leica LED5000 NVI is extremely high-performance thanks to its two integrated high-output LEDs. The light is generated nearly parallel to the microscope’s beam path and is thereby optimally aligned with the focal plane. This makes it particularly good for checking deep holes and bores.
The optional polarization set enables effective verification of high-gloss samples. The integrated filter insert makes it possible to adjust the light color to the user’s habits. This means the light characteristic of a halogen light source can be produced.
If you are working with a high-performance stereo microscope with high-magnification objectives (magnification of 1.6x or 2.0x), the illuminator provides excellent illumination at the smallest working distances.
Key Features
- Extremely high-performance LEDs: 2 high-output LEDs are extremely high-performance and effectively illuminate deep holes and bores. Perfectly for objectives with long working distances.
- Compact, well-integrated design: The integrated control element and compact design do not take up any more space on the work table.
- For high-performance stereo microscopes: For high-performance stereo microscopes, the Leica LED5000 NVI enables illumination of the specimen at very low working distances.
- Polarization set: With the optionally available polarization set, you can minimize reflections on metallic surfaces, which increases the efficiency during routine inspections.
- Efficient quality control: Excellent, high-performance illumination for standardized quality control processes.
- Highest modularity: The Leica LED5000 NVI can be combined with other illumination components and can be used flexibly.
Leica LED3000 DI
To document fissured samples with many corners, edges and recesses, you need a diffuse light source. Its light characteristic reduces shadows and does well at illuminating the digital images everywhere.
The diffuse illuminators of the LED illuminator series enable uniform illumination without bothersome shadow effects. They are particularly suited for documenting samples that are difficult to illuminate.
The illumination screen distributes light in all directions and produces a uniform light. Mounting it on a gooseneck gives you increased accessibility to the specimen. The flexible solution is ideally suited as a supplement for other illuminators and can simply be swung out of the way when not in use. The control element is mounted on a second gooseneck and can be easily positioned as the user desires.
Key Features
- Light characteristic: 36 high-output LEDs produce bright, uniform light.
- Flexible control element: The control element on the gooseneck can be positioned wherever it is needed – always at the right spot.
- Perfectly combinable: The modularity of the LED3000 DI means it can be easily and flexibly combined with other illuminators.
- Diffuse light: The bright, matte interior of the illumination screen ensures the greatest possible absence of shadows in the illumination – the best prerequisite for documenting quickly.
Leica LED3000 BLI for simple transmitted illumination
The Leica LED3000 BLI provides an easy option for equipping a microscope system with a transmitted light function. The 36 integrated LEDs produce sufficient brightness even for demanding tasks with transmitted light.
The built-in diffuser disk ensures high homogeneity of the light with a large object field diameter of 77 mm. The illumination can be combined with standard baseplates with a recess having a diameter of 120 millimeters and can be used as an independent instrument without a baseplate.
The intuitive touch panel makes the Leica LED3000 BLI extraordinarily easy to use. The large work surface of 170 mm x 220 mm also makes it possible to work easily with large samples.

High diffuse dome illumination Leica LED5000 HDI
The LED5000 HDI™ illuminator effectively blocks out ambient light and illuminates demanding surfaces with minimal reflections.
It is based on the concept of a dome illuminator and produces a very uniform light by means of the dome shape. The mechanically flexible design of the dome (Leica FlexiDome™) with silicone rubber eases your access to the specimen.
You save yourself a lot of time, since the specimen can be aligned in a focused state.
The highly diffuse, low-contrast illumination optimizes the dynamic range and therefore is excellently suited for critical image acquisitions such as LAS Montage or Leica StereoExplorer applications.
Key Features
- Leica FlexiDome™: Access to the specimen remains guaranteed even in a focused state. This eases repositioning of the specimen and saves a lot of time.
- Better and repeatable results: Optimization of the dynamic range often makes new information visible. This usually leads to improved results with digital image processing

Compact LED Ring Illuminator for Uniform Illumination Leica LED3000 RL
The Leica LED3000 RL ring illuminator guarantees bright, uniform illumination of the specimen over a large object field at a constant color temperature. This is achieved by using the latest generation of LEDs, but above all by using the focusing lens specially developed by Leica.
The compact design makes for easier side access to the various specimen.
With the control of individual segments (half rings, quarter rings), you can achieve different contrasts and thereby gain additional information from your specimen.
Key Features
- Specially developed focusing lens: This extends the uniformly illuminated object field and provides a constant color temperature
- Diffuser and polarization set: These accessories reduce reflection (diffuser) or eliminate it (pol. set)
- Supports objectives with a 58 mm diameter: Can be used universally with different instruments within the optimized working distance of 60 to 150 mm
