Structured illumination for microscopy
The µLight technology developed by leida Technologies allows to obtain images impossible to observe with conventional optical microscopy.
The simplicity of structuring the illumination of microscopic preparations in color and shape makes it possible to use it in routine.

The µLight sources are controlled by software. A click on a button allows to modify the lighting structure.
Each image provides different and often complementary information.

Multimodalities
The µLight sources allow to observe according to several modalities: brightfield, darkfield, Zernicke phase contrast, differential phase contrast, color coded oblique circular illumination, phase image, Fourier ptychography, digital holography.
A user can easily define his own illumination patterns to develop new methods.

Universal
The µLight sources can be installed on almost all microscopes, new and old, upright and inverted.
