EEE Light® UV Boost™

This groundbreaking UV nanostructured coating improves UV output of existing UV lamps, sleeves and UV transparent windows by up to 15% at 254nm. It has been extensively evaluated at 254nm using standard mercury low pressure lamps (LP Hg lamps). This proprietary layer is made with a simple wet chemical coating process followed by a short heat treatment. It has excellent adhesion and withstands repeated chemical cleaning. Patent applications are filed. The coating technology has been developed for cost efficient, large scale manufacturing and is easily added to existing production lines for UVC light sources.

Performance has been verified on soft glass (soda lime), borosilicate and quartz/fused silica. Typical results are shown below, obtained by inserting a LP Hg lamp into the glass tube, with and without the UV coating. To simulate a UVC lamp with a surrounding sleeve, measurements on the improvement using two concentric tubes has been performed as well.
