Phoseon Technology – A leader in UV LED solutions for Life Sciences and Industrial Curing applications


Ultraviolet (UV) LED stands for ultraviolet light emitting diode. A UV LED is an electronic light source with electromagnetic radiation that has a wavelength shorter than that of visible light but longer than x-rays. UV Light Emitting Diodes (LEDs) are a solid-state device that produces light when an electrical current is allowed to flow from the positive (p-type or anode) side of the circuit to the negative (n-type or cathode) side. This is called the ‘p-n junction’. Each LED is made to produce a specific narrow range of UV wavelength. Ultraviolet (UV) curing is a photopolymerization process that uses UV energy to change a liquid to a solid. Upon absorption of the UV energy, the photo-initiators produce free radicals which initiate cross-linking with binders (monomers and oligomers) in a polymerization reaction to cure or solidify the ink, coating or adhesive. UV formulations also incorporate various additives such as stabilizers, wetting agents, adhesion promoters, defoamers and pigments to provide desirable characteristics or color of the cured material.

Phoseon is one such innovative company offering UV light solutions for both life sciences and UV LED curing applications. By maximizing UV energy across relevant wavelengths, Phoseon provides solutions to a wide-range of applications including: LED curing, chromatography, decontamination, disinfection, fluorescence imaging, and photochemistry. Its extensive portfolio of products comes in a variety of sizes to match your application needs. In 2002, Phoseon Technology pioneered the use of LED technology for UV curing applications, and has now expanded into Life Sciences. As the world leader in UV LED technology, Phoseon provides patented LED technology to deliver rugged, high-performance products for application specific solutions.  The company is focused 100% on LED and provides worldwide sales and support capabilities. UV LED technology uses semiconductor based Light Emitting Diodes (LEDs) to project ultraviolet light when electric current is passed through the junction. These solid-state devices provide instant on-off capability with no warm-up time or mechanical shutters. Phoseon's rugged LED light sources deliver superior performance and integrated control based on patented Semiconductor Light MatrixTM (SLM) Technology. Phoseon builds on the inherent advantages of UV LED technology by delivering optimized solutions for demanding applications.

Phoseon’s patented Semiconductor Light Matrix (SLM) technology provides the optimum mix of power, uniformity and control.  Are you developing a new instrument for protein detection, interested in bio-inactivation for your research, or trying to disinfect microorganisms? If so, they support you.  Select Phoseon as your partner for highly-reliable, efficient and specialized light engines for life sciences. Phoseon provides solutions to a wide-range of applications including: chromatography, decontamination, disinfection, imaging, and photochemistry.

KeyLight™ Illumination Sources: Fluorescence microscopy requires an intense light source at the specific wavelength that will excite fluorescent dyes and proteins. Traditional methods utilize a white light that is typically from a mercury or xenon arc lamp. With these traditional methods, only a small percentage of the projected light is useful in any particular application. Phoseon engineers LED light sources for widefield fluorescence microscopy. LEDs use specific targeted wavelengths with much less need to suppress unwanted wavelengths from a white light arc lamp. KeyLight™ illumination sources for fluorescence microscopy deliver high performance imaging with easy integration for OEMs. Phoseon’s proprietary LED solutions offer intense, broad-spectrum UV and visible wavelengths for a wide variety of colors from UV through visible into the infrared. These compact light sources support 4 through 7 channel systems for greater flexibility depending on the application requirements. Phoseon’s KeyLight is ideal for molecular or cell biology labs and OEMs who are looking for an affordable, energy-saving, customizable, high-quality, and low maintenance option that allows easy integration.

UV Detectors for Liquid Chromatography: Phoseon’s KeyView™ products leverage patented Semiconductor Light Matrix™ (SLM) technology to improve both performance and ease-of-use over traditional light sources like deuterium, tungsten, and xenon lamps. LEDs are inherently low-noise, stable, cool and controllable. They turn on in milliseconds to full brightness and last for greater than 10,000 hours. KeyView products cover a variety of wavelengths while taking advantage of the long lifetime of the solid state technology. Conventional optical detection systems are bulky and slow to start, due to the arc lamps used as light sources. Phoseon’s LED-based detectors for high performance liquid chromatography (HPLC) have a number of advantages, such as small size and immediate operation.

KeyPro™ for Decontamination System: Potential biological contaminants are pervasive and invisible in the laboratory. Miniscule amounts of common enzymes such as RNase can invalidate an entire experimental series. Standard techniques for decontaminating laboratory equipment can take hours. KeyPro™ UV LED decontamination system eliminates contamination without residue or rinsing, saving up to 90% of the time and cost of chemical decontamination. Application of UV LED technology benefits researchers through improved reliability of starting materials, shorter time required for preparation and inactivation of RNases, all while protecting valuable RNA samples from degradation and chemical contamination. UV LED decontamination using Phoseon’s KeyPro™ products benefits labs that require high fidelity RNA library prep, sequencing and PCR, or for vaccine development labs that need to quickly and reliably inactivate viruses. Complete inactivation of laboratory contaminants, including the hard-to-kill RNase A, can be accomplished by the KeyPro UV LED decontamination system in under five minutes and at fraction of the cost of traditional methods.
