Prior Scientific has added the LDB100F and LDB101F Brightfield LEDs to its range of illumination products for microscopy. Replacing standard light sources, the Brightfield LED provides the advantages of LED illumination in a flexible package that can be fitted to most modern upright and inverted microscope systems. By using a Brightfield LED with a 550nm flip-in filter in the light path, background fluorescence attributed to stray light is reduced.
Benefiting from direct coupling to the microscope, the Brightfield LED maximises the amount of light transmitted to the sample. The LED produces minimal heat and vibration, minimising the chance of sample damage and reducing disruption during the imaging process. Homogeneous light with a constant colour temperature of 5500K is produced by the Brightfield LED, enabling illumination suitable for a wide variety of applications.
Light produced from the Brightfield LED is also intense enough to be used for contrast techniques, such as phase contrast or DIC imaging. The intensity of the light can be regulated manually giving complete control of the level of illumination. A TTL connection allows extremely rapid switching (< 140 microseconds) of the light, which negates the need for shutters and reduces any potential vibration.

Available in two varieties, the Brightfield LED can be either used as a stand-alone light source with its own power supply (the LDB101F) or controlled by Prior’s ProScan III control system (the LDB100F). Furthermore, Nikon microscope users can benefit from integrating a Prior Scientific Brightfield LED source into their Nikon Hub via the LDBNHUB adapter. This allows direct control from the microscope of the Brightfield LED as the transmitted light source. Also recognised by NIS elements as the transmitted light source, this provides a total integrated illumination solution for Nikon users.
