For renowned microscopy manufacturers this Know How makes PHOTONIC a sought-after light specialist. Our customers include all well-known companies in the light microscopy sector.
PHOTONIC’s comprehensive modular system for microscopy includes light sources for almost every task and is compatible with all common microscopes.
The LED product line for direct object illumination was developed by PHOTONIC in particular for illumination tasks in stereo microscopy. The modularity of the system permits an expandable and cost-effective lighting solution. In contrast to this direct illumination are fibre-optic light sources, which transport light to the object by means of light guides.
Tpye and direction of the lighting are decisive for the result.
Three approaches are used to achieve the optimal desired image contrast: Incident light (with ring light  or spot , offers the greatest light intensity with maximum flexibility and widest choice of lighting) and transmitted light .
One advantage of PHOTONIC LED ring lights is the option of switching partial areas of the ring light on or off, and rotating the segments selected in this way. In addition to providing homogeneous illumination, this also brings with it the option of creating directional lighting. Furthermore, the lighting delivers outstanding contrasting possibilities for surface textures due to the formation of shadows.
The latest member of this category is the High-Power Ring Light (HPRL), which uses 8 high-power LEDs to cast very powerful light over the working area. Also available is the series of external controllers with light heads, such as the High Power Spot and ring lights with 40 and 80 LEDs for widely diverse lighting tasks and working distances.
Fibre optic gooseneck light guides or flexible light guides in combination with an external light source are recommended for lenses with a short working distance and for higher contrast applications. These can be set at different angles to create a wide variety of contrasts.
Members of this category include the LED light sources F1, F3000 and F5100. A wide range of fibre optic light guides are available as accessories, e.g. ring lights, flexible light guides in different lengths and diameters and naturally also combination light guides that are fixed to the microscope column by means of adapters.
