With LUXYR and AMPYR LEJ markets two proprietary-developed lines of standard products, utilized specifically in microscopy applications. Especially in demanding Fluorescence, but also in routine Transmitted and Reflected Light microscopy applications the Xenon, Mercury and (multi-channel) LED light sources are employed worldwide.
The entire range of brand products can be customized according to customers and applications. By providing a modular design as well as an intelligent roadmap-based development platform, LEJ allows such customization to be conducted in a very short time (time-to-market) and at reasonable costs.
LEJ supports OEM customers with in-depth know-how in dimensioning Lamp-, LED- and (increasingly) Laser-powered Illumination Systems. LEJ is in the unique position to advise customers independent from the light sources, thus being able to develop and manufacture hybrid / multi-modal Illumination Solutions.
