The new LED-based solid state
light source.


Taking LEDs to a new level

The niji from Bluebox Optics is a revolutionary and innovative LED light source that is ideally suited to the demands of fluorescence microscopy.

Up to seven LED channels

With up to seven LED channels the niji delivers powerful, multi-wavelength excitation from UV to NIR. niji is the ideal LED light source for single and multiband fluorescence microscopy.

User-changeable LEDs and filters

niji’s uniquely reconfigurable mainframe allows you to change LEDs and filters in minutes, offering additional excitation centre wavelengths, excitation bands, and output power options.

Future-proof Investment

There’s no need to know today what wavelengths you need in the future. niji combines a low-cost entry point with an easy and low-cost upgrade path, making your investment future-proof.

Why it’s essential to go for an LED-based source?

For many years using mercury lamps were the way to go, but latest research results show that LED sources have a number of advantages over mercury lamps.

Low Power Consumption
Low power consumption delivers significant savings in whole life costs.
Zero Toxicity Materials
Materials with zero toxicity are safer and easier to dispose of.
Reduced Out-of-band Photo Bleaching
Both reduced out-of-band photo bleaching as well as filter bleed-through deliver clearer images.
Controllable Low Level Light
Controllable low level light results in reduced photo bleaching and toxicity.

LEDs are better, but don’t just take our word for it.

Reducing the Risk of Mercury Exposure for a Sustainable Future

Future-proof made easy

The niji comes your way. You can buy the complete niji system pre-loaded with all seven modules or just choose the colours you need and upgrade later!
Numerous adaptors, light guides, and collimators are available to go with most standard microscopes.
