Fiber-Coupled UV-LED Light Sources

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.

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.

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).

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.

Additionally, you can also combine any other UV, VIS or NIR emitters. One example is a version for life science applications.

• 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.

• 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 subsystem 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.

• ALE/1’s future-proof data interfaces as well as its network oriented electronic component and software setup allow for a seamless integration in your (automated) production environment.
• Besides intuitive user interface via the touch display, there is a variety of standard interfaces supported by the ALE/1 (incl. AUX for external switching devices, USB for ALE/remote Software, Discrete PLC Interface, and Fieldbus)
