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.
1 CWL of emitters: 367.5±2.5 nm, 387.5±2.5 nm, 402.5±2.5 nm, or 435.0±2.5 nm; 2 Full spectrum of each emitter measured at end of light guide (length 1.5 m), deviation of ±10% possible; 3 Light guides with antireflective coating are available with additional output of 7%.
ALE/1.2 (2 LED-Setups)
There are several 2-LED-combinations available, depending on your application needs. Potential setups including 2 high-performance UV-LEDs are: 365/385 nm, 385/405 nm, and 365/405 nm. These spectra are particularly popular in industrial UV-LED spot curing applications.
1 CWL of emitters: 367.5±2.5 nm and 387.5±2.5 nm; 2 Full spectrum of each emitter measured at end of light guide (length 1.5 m), deviation of ±10% possible; 3 Light guides with antireflective coating are available with additional output of 7%.
ALE/1.3 (3 LED-Setups)
Two 3 LED-setups in the UV spectrum are available: Covering the spectrum from 365 nm to 405 nm with high UV radiation power, the ALE/1.3 (365/385/405 nm) is particularly suited for curing applications. This configuration with 3 high-performance UV-LEDs provides you with full flexibility to combine and select the wavelengths available in order to profit from a broad spectrum exposure.
1 CWL of emitters: 367.5±2.5 nm, 387.5±2.5 nm, and 402.5±2.5 nm; 2 Full spectrum of each emitter measured at end of light guide (length 1.5 m), deviation of ±10% possible; 3 Light guides with antireflective coating are available with additional output of 7%.
Furthermore, there is the option to combine and select from wavelengths of the i-, h-, and g-line spectrum (365/405/435 nm) in semiconductor lithography applications. Whether you want to switch between bandwidths or want to use a broader spectrum the ALE/1.3 is able to provide you with highest radiation output up to 30 W (all emitters combined).
1 CWL of emitters: 367.5±2.5 nm, 402.5±2.5 nm, and 435.0±2.5 nm; 2 Full spectrum of each emitter measured at end of light guide (length 1.5 m), deviation of ±10% possible; 3 Light guides with antireflective coating are available with additional output of 7%.
ALE/1.4 & ALE/1.5 (4-5 LED-Setups)
The ALE/1.4, combining 4 high power LEDs in its optical path, covers the entire spectrum from 365 to 435 nm with high radiation power. For photoresists that profit from a broad wavelength spectrum and/or are sensitive also to 385 nm, the ALE/1.4 will be your choice.
1 CWL of emitters: 367.5±2.5 nm, 387.5±2.5 nm, 402.5±2.5 nm, and 435.0±2.5 nm 2 Full spectrum of each emitter measured at end of light guide (length 1.5 m), deviation of ±10% possible; 3 Light guides with antireflective coating are available with additional output of 7%.
Also, you may want to combine any other type of UV, VIS or NIR emitter. One example is a version for life science applications.

Additional Features and Benefits
Unprecedented Usability and Process Control
Initial setup of the unit and internal emitters is a matter of minutes.
High resolution intensity adjustment and feedback controlled power output guarantee unprecedented precision and stability of your exposure process.
The ALE/1 is extremely fast, characterized by output rise times of less than 10 milliseconds.
Extensive possibilities to set up each LED-Module and general exposure parameters help you to manage your application processes and enable new applications.
Long LED service life and single minute exchange of LEDs, which can be performed by the end user himself, dramatically reduce equipment downtime.
Full Flexibility for System Integration
Primelite LED Light Engines are designed as fiber coupled light sources to achieve maximum flexibility for system integration.
High transmission light guides efficiently transport the generated radiation to the point of application – no need for complex optics, less trouble finding the right place for the LED light source to fit into your manufacturing equipment.
Upgrading valuable existing equipment and designing new exposure units based on Primelite’s latest LED technology is straightforward.
The small footprint of the internally cooled light engine, application of high transmission light guides and standard communication interfaces make system integration a very manageable task.
