The illuimination package that can be fitted to most modern upright and inverted microscope systems.  The LDB100F and LDB101F Brightfield LEDs come equipped with a 550-nm flip-in filter in the light path to reduce background fluorescence attributed to stray light.

Benefiting from direct coupling to the microscope the Brightfield LED maximizes the amount of light transmitted to the sample. The Brightfield LED produces minimal heat and vibration, thereby minimizing the chance of sample damage and reducing disruption during the imaging process. Homogeneous light with a constant color temperature of 5,500 K  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 even 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. The Brightfield LED has a TTL connection allowing rapid switching (< 140 usec) of the light which negates the need for shutters and reduces any potential vibration. Available in two varieties, the Prior Scientific 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).

Nikon microscope users can benefit from integrating a Prior Scientific Brightfield LED source into their Nikon Hub via the LDBNHUB adapter which 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.
