UV-LED Flood Exposure

Intensity, Uniformity, Collimation – Everything You Need for Precise UV Exposure

Let Us Turn Our UV-LED Light Sources into Ultra-Precise Flood Exposure Tools

Mask aligners and steppers create layer upon layer of precisely positioned and structured patterns to make complex integrated circuits, compound semiconductors, and other microelectronics. Many UV curing use cases require exposure to be as precise as in semiconductor production, but have no need for multiple lithography steps with meticulously aligned layers of microstructures, for example:

  • Edge exposure in smartphone and tablet display manufacturing
  • Safety features created for the printing industry
  • Biotech microfluidics applications

All of the above use collimated light. You can also integrate our solutions in UV-LED flood exposure setups requiring little or no collimation. A typical use case is UV curing that calls for a great deal of uniformity over a defined surface area.

Integrating Our UV-LED Technology into UV Flood Exposure Applications

Our modular product range lets you choose all components to suit your exposure requirements.

Opt for our ALE/1 or ALE/3 UV-LED light sources to suit your preferences for output power, spectral composition, and exposure stability. The Advanced Light Engine ONE is among the highest-performing fiber-coupled light sources on the market. Our Advanced Light Engine THREE is a more economical option with a smaller footprint.

Standard and customized high-transmission liquid LED Light Guides are available to link the light source and exposure. You are free to choose what works best for you. And you can position the light source and exposure optics practically anywhere in your setup’s design envelope.

You are likely to find components in our LED Performance Optics portfolio that generate an exposure beam to match your specifications. If not, our engineering team can always help and design a solution tailored to your needs.

Benefits of Broadband UV Curing

Primelite’s broadband UV-LED light sources deliver precisely the spectral composition that works best with your UV curing application. Choose from a range of available central wavelengths (CWL 365, 385, 405, and 436 nm) and define their output intensity separately. You can opt for the same output setting for every shot, a changing output profile during a shot, or subsequent shots with an individual spectral composition. With these capabilities, our UV-LED spot light sources can process almost every UV-sensitive material at impressive speeds and with phenomenal reliability.

A fully customizable output spectrum is particularly helpful if you are searching for a UV-LED solution to replace mercury discharge lamps in medical or pharma manufacturing equipment. Simply replicate the spectrum of your current spot light source and keep using your originally validated recipes.
