BEYOND THE SPECTRUM OF VISIBLE LIGHT
Ultraviolet radiation is invisible to human eyes, but plays an important role in many physical and chemical processes. Therefore it finds various applications in the industry and in scientific research.
Almeco developed three different types of vega®UV surfaces, each of them having its own areas of application:
vega®UV is widely used in curing processes, where the energetic UV radiation is used to initiate photochemical reactions. Several types of inks, coatings and adhesives contain special additives that cause polymerization when exposed to ultraviolet light. The high reflectance of vega®UV can help improve the efficiency of these processes.
vega®UV-A is suitable for suntan lamps. UV-A light sources can make certain substances visible by causing fluorescence, for example in forensic applications and in the evaluation of gems and art pieces. Many insects can see near UV, so insect traps use these wavelengths to attract them.
vega®UV-B finds application in the medical field, for example in light sources for the treatment of psoriasis and other skin conditions.
vega®UV-C accelerates the sanitizing action of UV rays. Because of its reflectance, it is usedto increase the efficiency of UV light sterilization systems for environments and objects. With sufficient doses, UV-C is a very reliable, fast and environmentally friendly disinfection method.

When used in a suitable application, vega®UV materials offer a performance improvement compared to the typical polished or anodized aluminum reflectors.In many UV applications the dose of radiation is a key parameter. With a better reflector, the required dose can be reached more quickly or using less powerful sources, thus improving efficiency.
vega®UV reflective aluminum surfaces can be used as reflectors to channel the output of UV sources. They can also be used to cover the internal walls of devices and reduce unwanted absorption.To considerably improve the effectiveness and efficiency of the appliances, Almeco’s optical engineers can support you in the development and production of reflectors to optimize the distribution of UV radiation by concentrating it where it is needed.
