This futuristic laser has a truly captivating color that is very similar to ultraviolet: It shines blue-violet, when looked at in smoke, and appears in brilliant royal blue, when seen on a white surface such as projection screens. Since the human eye is far less sensitive to blue than to green, blue lasers require more power to generate similar sensations as green ones. This 50mW blue-violet laser pointer is a great solution. Its fine beam is visible by night and its very bright blue spot is visible by day and night. Used by world leading experts in business and science to convince their audience and create unforgettable impressions. High Quality Guaranteed Many lasers on the market (especially on eBay) do not reach their promised output power. To guarantee that you get what you pay for, we test our lasers at a professional laboratory. This expensive service is included in the price and ensures that the emitted blue-violet beam remains stable at its high power.
