Single Multiband Wavelength Excitation for a Mercury Free Microscope
Go mercury-free. niji, the new state-of-the-art LED light source helps to eliminate mercury from microscopy.
The niji is a revolutionary innovation in mercury-free microscopy, taking advantage of recent advances in lighting technology. With a much smaller environmental impact, this low cost modular LED source with single or multiband wavelength illumination is leading the way. We care about the environment and are trying to help users who care too. The niji can help you to remove dangerous toxins and has far less power consumption than damaging mercury lamps, helping to do your bit toward the environmental impact of research. We’ve tried to use the latest technology to reduce the impact of production but also used old technology and made our packaging recyclable or degradable where possible. You may also be able to benefit from a sustainability grant from your institution to help you switch to new “green tech”.

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 and affordable upgrade path suitable for use in research institutes, hospitals, universities and pharmaceutical companies. No need to know today which wavelengths you’ll need tomorrow with our mercury-free, modular lab equipment.
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.
Fully compatible with microscopes and microscope software
Fully compatible with most standard microscopes, MicroManager, MicroManager 2, Metamorph and a wide range of other software packages from the major manufacturers. Contact us for more information. We also supply a universal collimator with common adapter rings for mechanical fitment.
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.
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. If you would like to find out more about our niji LED light source for single and multiband fluorescence microscopy, please contact us today.
