Advanced UV-LED Light Engine ONE

The Flexible and Most Powerful Ready-to-Use LED Spot Light Source for Demanding Use Cases

Versatility Meets Performance: ALE/1 Fiber-Coupled UV-LED Light Sources

The fiber-coupled UV-LED light source ALE/1 (Advanced Light Engine ONE) delivers high-power radiation precisely where you need it. Our flexible high-transmission LED Light Guides give you a lot more leeway in designing your next-generation exposure setup. These LED Light Guides’ length can range anywhere from 0.5 to 20 meters, so even the distance between the light source and target point is not an issue.

Your options for customizing the output composition of ALE/1 LED light sources are many. With our modular hardware, you can combine up to five individual high-power LED emitters in the near ultraviolet (NUV), visible (VIS), and near infrared (NIR) spectral ranges. On top of that, you can count on Primelite’s fiber-coupled ALE/1 LED systems to provide extremely stable high-power radiation.

ALE/1 UV-LED Fiber-Coupled Light Source Highlights:

ALE/1 UV-LED Fiber-Coupled Light Source Overview

We engineered our ALE/1 LED light sources with maximum versatility, speed, and performance in mind. Fast and powerful, these systems rise to the challenges of even the toughest exposure jobs we have come across. They will serve you well for a wide range of tasks.

Our ALE/1 Light Engines get the job done in high-volume automotive assembly lines, reliably curing components at high speeds. They satisfy the strictest quality specifications for manufacturing medical devices and live up to the semiconductor industry’s exacting standards for extremely sensitive photomask and reticle inspection processes.

Modular All-in-One LED Exposure System

Our fiber-coupled ALE/1 Light Engines put you in the driver’s seat. It takes mere minutes to set up the unit and all internal LED modules. Maintenance is just as fast and convenient, with no special tools needed to replace LED modules.

To adjust the output as needed, simply set the desired power levels for any installed LED module individually and in high resolution. To enable ultra-precise exposure, ALE/1 LED Light Engines achieve full optical output in less than a millisecond and stabilize all LED modules with closed-loop feedback to control emitted power.

Our ALE/1 Light Engine features an intuitive touch display for system setup and supports various standard interfaces to operate the unit. These include debounced inputs for simple external switching devices, USB (serial), a discrete PLC interface (TTL), and Ethernet or Modbus communication.

High-Transmission Liquid Light Guides for LED Sources

LEDs are high-NA light emitters with a broad angular radiation pattern. Efficiency is paramount in setups that pair LEDs with light guides: These light guides have to transmit maximum radiation to the target point. This means the LED source’s NA has to match light guide’s NA, which is why conventional low-NA fiber light guides cannot do the job.

We offer single- and multi-pole LED Light Guides perfectly matched to our ALE/1 LED light source. They typically deliver two to three times as much power as conventional fiber light guides, yet are just as flexible and long-lasting.

Choose standard or custom LED Light Guides to suit your needs. Options include:

  • Optimized transmission spectrum (UV, VIS, or NIR Core)
  • Active core diameter: Ø5.0, Ø6.5, and Ø8.0 mm
  • Any customer-specific length up to 20 m

LED Performance Optics

Be sure to check out our LED Performance Optics. Our LED Light Guides’ numerical output aperture is around 0.6 (α ~ ±35°), so our lens systems are a remarkably affordable add-on to reduce divergence or even focus radiation for maximum intensity. Our LED Performance Optics are also an excellent choice if you want to improve the uniformity of the exposure field, which can be hexagonal or square.

Primelite’s LED LED Performance Optics exclusively use UV-grade material.

ALE/1 UV-LED Fiber-Coupled Light Source Output

Our ALE/1 Light Engine is a platform accommodating up to five individual high-performance LEDs in the optical path. Combine LEDs as you see fit for much higher radiation power levels across a broad output spectrum.

Choose from a wide range of options to design the spectral composition of your ALE/1 fiber-coupled light source. We offer high-power LED modules in the near UV (NUV), visible (VIS), and near infrared (NIR) spectral ranges.
