The Saphire Sky projects a deep blue saphire color.. It uses low power and produces bright graphics and beams. Using a connected computer with Show Designer software you can select from a library of graphic images and animations to build a custom show. You can type in words or sentences and have them written out in vibrant laser color. You can also create beams and sky effects with this laser. The Saphire Sky requires an operator with the rental system and a variance filed for each show. This is an easy online process. It can work in standalone mode by projecting an assortment of preloaded beam effects. This color of blue was basically unavailable a few years ago and all blue lasers were very expensive. Not any more
