L.E.S.S. microscopy ring lights combine high uniformity and high directionality in a unique way. These properties allow for an unprecedented inspection comfort offering high contrast images, reduced stray light reflections and therefore a lower eye fatigue. No heat is dissipated from the light sources which enhances the comfort of the user.
Dedicated to the inspection of surface and reliefs, the BF-5400 is easy to set-up and easy to interface to an optical system. BF stands for brightfield: an acute light strikes the sample at high angles resulting in crisp, well defined 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.
Dedicated to the inspection of prints and edges, the high lighting directionality of the DF-5400 provides comfortable working conditions for the inspection of the whole sample with naked eyes in a standalone use or for a more detailed examination under a microscope.
DF stands for darkfield: a sharp and fine light surrounds the sample from the side, at low angle, resulting in high contrast images with an emphasis of the sample edges and relief. It gives key information on the manufacturing quality of metallic, glass or plastic components and enables the optimal detection of material deposits.
The brightfield and the darkfield exhibit the same optical properties of ultra-uniformity and directionality as well as the same colour temperature. Independently of the number of hours the products are used, the light temperature of 5400 k remains constant throughout the systems longevity. This consistency enables the users to maintain a stable quality standard over time.
Easy to set-up and easy to interface to an optical system, the bright- and darkfield ring lights can be used as a combo with different microscopes such as Zeiss, Olympus, Nikon, Leica or other microscope brands.
