Our partner LEJ present their portfolio – high-performance illumination and power electronic solutions

LEJ is your provider of high-performance illumination as well as power electronic solutions in the fields of microscopy, analytics, semiconductor, industry and medical technology. 

Besides its comprehensive portfolio of brand products LEJ offers the highest degree of flexibility and speed to bring customer-/application-specific products to the market. World-known OEMs count on LEJ as their system provider for e.g. laser and system power supplies, LED high performance controller as well as partner for contract assembly of complex opto-mechanical and opto-electronical sub-assemblies and systems. 

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.
