Fibre Optic illuminators
An extensive range of fibre optic light guides and filters to suit a wide variety of illumination tasks is available. Flexible light guides allow easy adjustment, while swan-neck guides are also self-supporting. Multi-branch versions allow illumination from a number of directions and with different colours if required. Ring lights can be mounted onto the objective lens of a stereo microscope to provide shadow-free illumination. Combined with a high intensity, heat-free and directional light source a continuously adjustable range of light intensities and colour temperatures is possible. For photographic applications, the brightness can be adjusted while maintaining constant colour temperature. A built-in heat filter removes the infra-red component of the bulb output, and coloured filters can be used as desired.
