Niji LED light source

Share this on social media:

Bluebox Optics has introduced a modular LED light source ideally suited for fluorescence microscopy.

The firm identified the demand for a flexible and future-proof LED light source for single and multiband fluorescence microscopy after speaking to researchers. With the Niji’s reconfigurable mainframe, LEDs and filters can be changed by the user in minutes, meaning users do not need to know today what wavelengths they might need in the future.

With up to seven LED channels, the Niji delivers powerful, multi-wavelength excitation from UV to far red. The Niji allows users to start with a single LED, with the option to add up to six more LEDs at a later time, offering additional excitation centre wavelengths, excitation bands, and output power options as and when they are needed.

Both constant current and constant optical power LED drive modes are selectable, enabling fast imaging speed and high excitation power stability over long periods. Wavelengths, power, and emission channel can all be controlled individually or simultaneously, and the Niji is fully compatible with most standard microscopes, MicroManager, MicroManager 2, and a wide range of other software packages. It is also a very quiet tool, which is much appreciated by users.
