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.
LEJ supports OEM customers with in-depth know-how in dimensioning Lamp-, LED- and (increasingly) Laser-powered Illumination Systems. In the field of Power Electronics customers benefit from durable, productive, long term available solutions that, at the same time, deliver reproducible and quantifiable results. Being vertically integrated LEJ offers value added engineering & assembly in system business.
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.
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. In the field of Power Electronics customers benefit from durable, productive, long term available solutions that, at the same time, deliver reproducible and quantifiable results.
Fiber optic LED light source module with modular design for integration into customer equipment or systems. The modern driver technology allows analogue brightness control and fast pulsing of high-power LEDs via Ethernet or USB, as well as the implementation of an electronic shutter. The coupling of the LED to the optical fiber by a specially developed fiber optics is highly efficient and guarantees maximum light flux even at small active
The 2- or 4-channel digital lighting controller from LEJ for actuating high-power LED groups allows the precise setting of the LED current, the pulse length and pulse delay across a wide range separately for each channel. Also independent for each channel, the operating modes DC, Pulsed or Switched can be selected.
The controller is configured by ethernet via the internal web server or by USB directly from the user software or a service program.
