Fiber-Coupled UV-LED Light Sources - Primelite Advanced UV-LED Light Engines

Our high-performance LED spot light sources are Primelite’s ready-to-use solution for demanding applications.

A high degree of flexibility and customization in spectral composition is achieved by our modular concept with up to 5 separate emitters based on UV-LED and VIS-LED technology. Extremely stable output and extended lifetime characterize this spot light system. For efficient delivery of the radiation at the point of application, we recommend and use high-transmission liquid light guides (see Optical Subcomponents).

Our ALE/1 systems are developed and manufactured in Munich – Quality Made in Germany.

Multispectral Modularity for Highest Intensities

The ALE/1 combines radiation power and spectral characteristics of a mercury discharge lamp with the TCO and process benefits of LED technology. Following a platform concept approach, the ALE/1 is capable of combining up to 5 high-performance LEDs in the optical path. This allows for significantly elevated radiation power levels across a broad output spectrum.

Choose from a wide range of options to design your spectral composition of ALE/1 systems: UV-LED Modules in the Near UV (365, 385, 405, 435 nm), VIS-LED (470, 520, 620, 660, 690 nm) and NIR-LED emitters (730, 770, 810, 850, 970 nm) are available.

The emitters are available as “Regular” LED-Modules in combination with 5.0 or 6.5 mm light guides or “Plus” LED-Modules for elevated performance combined with 6.5 or 8.0 mm light guides.

Examples of Potential Combinations and Related Performance Levels

ALE/1.1 (1 LED-Setups)

This ALE/1-setup provides highest radiation intensity focusing on a single peak wavelength. If your application is optimized for narrow bandwidth radiation and does not profit from a broad spectrum, the ALE/1.1 is your preferred choice as a high output UV-LED spot curing system.
