About us

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 their 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.

AMPYR® LED Evaluation Kit

AMPYR® LED Evaluation Kit

The AMPYR evaluation kits LED30UV have been developed for the fast and easy evaluation of LEDs up to 25 W.
Using the the LED30UV it is possible to carry out initial tests and test series with
▪▪ UV-C LEDs, e.g. for disinfection, water treatment, light therapy, sensors and falsification detection,
▪▪ UV-B LEDs, e.g. in biotechnology, phototherapy, medical photometry as well as
▪▪ UV-A LEDs, e.g. in medical technology, light-curing and image processing
