niji LED light source for microscopy

Go mercury-free. niji, the new state-of-the-art LED light source helps to eliminate mercury from microscopy.

But, why should I choose a niji?

Benefit from the uniquely reconfigurable mainframe and the future-proof design of the niji.

niji combines a low-cost entry point with an easy, low-cost upgrade path. No need to know today what wavelengths you need tomorrow.

Individually addressable, individually filtered LED channels

The niji delivers powerful, multi-wavelength excitation from the UV to the NIR, specifically designed for single and multiband fluorescence microscopy.

Individual excitation filters

Each LED can be filtered at the source, allowing the user to sequence images very quickly.

Constant current and optical power LED drive modes

Both constant current and constant optical power LED drive modes are selectable, enabling fast imaging speed and high excitation power stability over long periods.

User-changeable LEDs and filters

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

Fully compatible with microscopes and microscope software

Fully compatible with most standard microscopes, MicroManager, MicroManager 2, and a wide range of other software packages.

Control individually or simultaneously

Wavelength, power, and emission channel can all be controlled using the manual controller (tablet), via software, or both at the same time.
