ALE/1C UV-LED exposure systems deliver highest output levels matching the illumination power of 1 kW and 2 kW mercury arc lamps.
Primelite’s Advanced Light Engine ONE C (ALE/1C) is a high-intensity incoherent spot light source for multipurpose industrial applications. It is based on UV-LED technology, offering various advantages over traditional high-pressure mercury discharge lamps, such as reduced power consumption and heat generation, extended service life, and less maintenance on the overall setup.
ALE/1C UV-LED exposure systems are built on a platform concept, which can combine a maximum of three UV-LED emitters in its optical path. These light sources are typically used in photolithography processes (semiconductor manufacturing) and industrial light curing applications.
Our ALE/1C systems are developed and manufactured in Munich – Quality Made in Germany.
- Built-in solution for maximum efficiency and performance
- Up to 50 Watts of broadband exposure (UV-LED 350-450 nm)
- Closed-loop controlled output
- Future-proof mercury-free light source
- LED process stability and TCO benefits
- Quality Made in Germany
Distributed Setup for Optimal OEM-integration
ALE/1C units follow a distributed design approach, typically made up of a Control Subsystem (CSS) and a single or multiple separate Exposure Subsystems (ESS). Very compact, yet extremely powerful: This design principle of our UV-LED exposure head allows for easy integration directly into your equipment. The light exit our Exposure Subsystem may be combined with a variety of available light pipes, light guides and additional (also customized) optics.
Control Subsystem (CSS)
There are two versions of the CSS available: A stand-alone unit and a 4U 19” rack mount unit. Both ALE/1C CSS versions feature the same control interfaces, cooling system connectors, and a system status indicator. Additionally, the rack mount version provides an Exposure Test Key Switch on the front to activate light output without the requirement of external control signals.
Exposure Subsystem (ESS)
ALE/1C light engines are light pipe coupled spot light sources. The system features a compact Exposure Subsystem (ESS), which can easily be integrated into your existing equipment (retrofitting) or new designs. Connected to a separate Control Subsystem (CSS), this UV-LED light engine provides all hard- and software necessary to control and drive the solid-state emitters, as well as all required optical components.
Light Exit Options and Optics
We offer a selection of flexible liquid light guides, light pipes, homogenizers and condensing optics to be combined with the ALE/1C ESS. These components are particularly helpful, if you need to transmit high-power radiation over long distances, increase uniformity, or want to adjust the collimation angle of the output radiation. Please check our Primelite Performance Optics page for further information.
Standard Photolithography Setup with UV-LEDs 365 nm, 405 nm, and 435 nm
Our standard ALE/1C+ setup combines UV-LED emitters with peak wavelengths around the i-, h-, and g-line (365 / 405 / 435 nm) of the mercury spectrum. Whether you want to switch between wavelengths without changing filters, customize the compositon of your output spectrum, or want to make use of very intense broadband exposure, our ALE/1C+ provides you with highest UV-LED based radiation output in the spectral ranges between 350 nm and 450 nm.
Total output of our ALE/1C+ is up to 40 W and up to 50 W with an additional external chiller added to the cooling circuit.
