3D a high contrast imaging!

Oblique illumination has long been known and used in light microscopy, but in recent times, it has become a very popular way of illuminating samples when observing them under light microscopes in modified bright-field mode. To achieve oblique illumination, the light beam from the light source of the microscope is adjusted so that it illuminates the object only from a specific direction and at a certain angle out of the optical axis of the microscope. This results in an image with an increased contrast and plasticity of the observed object.

Our Lumicra sliders ensure efficient use of oblique illumination in your light microscope. The Lumicra sliders will provide you with a highly efficient way of creating contrast imaging with minimal costs while providing all its benefits of advanced imaging with minimal costs. The resulting high contrast 3D images of the observed sample will help you observe the finest details in difficult-to-observe objects, such as bacteria, cells, protozoa, sperm, fibres, diatoms, aquatic organisms and others.

Oblique illumination with Lumicra sliders achieves very similar results as when using advanced contrast light microscopy methods, such as Nomarski DIC, phase contrast, Hoffman contrast. Moreover, it provides a more efficient and affordable solution compared to the abovementioned methods. Lumicra sliders are, therefore, suitable for scientific, student and routine microscopes.

Solusions for Leica microscopes

Practical all-metal Lumicra sliders with rubber handles ensure comfortable adjustment of oblique illumination with the Leica microscope. The inserts are multi-position, where each position of the Lumicra insert has a specific shape and design, so they can easily adjust the transmitted light and change its character – the amount and the angle of the transmitted light. The sliders can, therefore, also be adapted for use with microscope lenses of various magnifications and numerical apertures.

Sliders for oblique illumination Lumicra

In our product offerings, you will find several versions of sliders that are fully compatible with the Leica DM500, DM750 and DM1000 light-microscope models. The inserts are designed for the supported condenser No. 13613 (and are also compatible with other supported condensers), which can also be purchased from us, if of interest.
