ALE/2 UV-LED Exposure Systems to Replace Conventional 2 - 5 kW Lamp Houses

Primelite’s UV LED Exposure System Advanced Light Engine TWO (ALE/2) is a high-performance UV spot light source for large substrate industrial flood exposure tools requiring perfectly uniform and collimated radiation. These may be 8” or 12” mask aligners. Its UV output is strong enough to power even larger setups with square exposure areas measuring up to 400 X 400 mm – and in some cases, beyond that. Featuring UV LED technology, the ALE/2 outperforms conventional high-pressure mercury discharge lamps with excellent output stability and flexible spectrum control. It also consumes less power, does not generate as much heat, lasts longer, and requires minimal overall maintenance.

ALE/2 UV LED Exposure Systems make the most of Primelite’s technology platform for you to combine four feedback-controlled high-power UV LEDs in the optical path. i-line (CWL 365 nm) and broadband (CWL 365 / 405 / 436 nm) configurations are available. In i-line-only processes, the ALE/2 UV-LED Exposure System matches the performance of conventional discharge lamps rated for up to 5KW. For broadband use cases, its illumination power rivals that of 2K W discharge lamps.


Highlights:

• Built-in solution for maximum exposure efficiency and performance
• Up to 70 watts of i-line exposure (CWL 365 nm)
• Up to 80 watts of broadband exposure (350 - 450 nm)
• Closed-loop controlled optical output for maximum process stability
• No mercury! Safe and future-proof LED light source
• UV-LED technology for longer life and lower TCO
• Premium, made-in-Germany quality
