Microscopy lighting in brightfield

High angle illumination

Microscopy brightfield illumination BF-5400

Dedicated to the inspection of surface and reliefs, the BF-5400 is easy to set-up and easy to interface to an optical system be it Zeiss, Olympus, Nikon, Leica or other microscope brands.

In a brightfield configuration, an intense light directly strikes the sample at high angles, from a plane located above the sample. The brightness provided by the brightfield combined with LESS unique light uniformity results in crisp, vivid images.

The high light quality allows to work at a lower intensity. This allows to eliminate the presence of stray light reflections and offers a greater comfort for the operator while maintaining an optimal image quality in terms of contrast and relief.

The color temperature of the brightfield is 5400 K (6500 K option on request). Independently of the number of hours the product is used, its light temperature remains constant throughout its longevity. This consistency enables the users to maintain a stable quality standard over time.
