Brightfield LED Illumination for Upright & Inverted Microscopes

Prior Scientific has announced two additions to their wide range of illumination products for microscopy - the new LDB100F and LDB101F Brightfield LEDs. Using a Brightfield LED with a 550 nanometre flip-in filter in the light path reduces background fluorescence attributed to stray light.

The Brightfield LED replaces the standard light source and provides all the advantages of LED illumination in a flexible package that can be fitted to most modern upright and inverted microscope systems.

Benefiting from direct coupling to the microscope the Brightfield LED maximises the amount of light transmitted to the sample. The Brightfield LED produces minimal heat and vibration, thereby 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 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 extremely rapid switching (< 140 microseconds) 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). 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.
