Primelite’s multipurpose LED sources for high-power special lighting applications, like non-destructive testing (NDT) or fluorescence analysis in life sciences.

Our LED light sources do an outstanding job in semiconductor manufacturing and challenging UV-curing applications. Many features of our products are beneficial if you need to establish robust processes and can be very helpful in other industries relying upon stable UV, VIS, and NIR exposure, too. Highlights of Primelite’s LED Light Engines are:

  • Future-proof mercury-free light source
  • Advanced LED technology (improved total cost of ownership)
  • High radiation output
  • Customizable spectral composition (UV, VIS, NIR)
  • Excellent short and long term exposure stability (closed loop controlled)
  • Easy to integrate into new and existing setups
  • Quality Made in Germany

Two significant areas of applications taking advantage of our standard-setting LED exposure technology are non-destructive testing (NDT) of safety-critical components and fluorescence analysis in life sciences.

Quality Assurance and Inspection (NDT)

In the aerospace, automotive, medical, and power generation industry, non-destructive testing (NDT) is a prevalent process when manufacturing new parts or during the inspection of safety-critical in-service components. A quick and reliable low-cost method to inspect your critical parts for cracks or flaws is Fluorescent Penetrant Inspection (FPI), which is also known as Dye Penetrant or Liquid Penetrant Inspection. The process itself does not cause any damage to your part and allows a qualified inspector to make solid evaluations.

Fluorescent Penetrant Inspection works on non-porous materials, such as metals, plastics, ceramics, and glass. Surface cracks, that propagate once a critical size is reached and lead to catastrophic part failure, become observable under black light (NUV radiation) during the inspection process.

Depending on the volume or on how critical your parts are, FPI systems can be anything from manual to fully automated. Regardless of the setup, all FPI applications need powerful and reliable lighting solutions to maximize quality and safety.

Our high-power LED light sources originate from semiconductor manufacturing, a production environment with minimal tolerance for errors or defects. Built to deliver very intense output with excellent repeatability regarding exposure timing and stability, our LED light sources set new industry standards in quality assurance and non-destructive testing.

There are many options to integrate our LED solutions into your process: As we offer both, customizable built-in and fiber-coupled stand-alone systems, you have a broad range of options to upgrade illumination in your NDT application to next-generation LED technology – be it a flexible endoscopic use case or a fully automated stationary setup.

Life Sciences

Lighting used for fluorescence applications (e.g., microscopy) must be impressive down to the finest detail. Clinics and research laboratories want to get more work done in less time. For them, the intensity is essential in the most demanding applications. High power light sources covering a broad, continuous spectrum from the near-UV to the far-red perfectly meet these requirements.

Fluorescence microscopy and other visual inspection applications are extremely light-hungry. In a typical research-grade microscope, throughput loss of the illumination system often exceeds much more than 80% of the provided input power, depending on the number of filters, mirrors, prisms and lenses in the optical path.

Historically, mercury arc-discharge lamps offered the best performance for fluorescence applications. It is only logical that fluorophores have been developed, matching the spectral peaks of those lamps in an ideal way. However, the introduction of green fluorescent proteins revolutionized the life sciences industry, because of it’s substantial benefit in live-cell imaging. It smoothed the way for a broad acceptance of off-peak excitation. Hence, fiber-coupled metal halide light sources were very well received in the market, which significantly improved excitation intensity for dyes that have absorption bands falling in the spectral regions between the mercury lines.

Primelite’s LED Light Engines comply entirely with the desire for more optical power, distributed over a broad, continuous spectrum from NUV to NIR. Like most metal halide lamps, Primelite’s ALE/1 LED light source for life sciences and visual inspection is a fiber-coupled system using liquid light guides for maximum compatibility with existing research and testing equipment.
