The UltraLite ALS from Versalite features Blue-Merge Technology (BMT). This patent-pending technology combines a unique blend of short wave forensic wavelengths. The BMT lamp allows users to detect 99.5 percent of evidence using only the BMT light and one filter. At 6 inches by 4 1/2 inches by 1 1/4 inches and 300 grams (including battery option), the UltraLite ALS is a small and lightweight forensic system. With more than 1,000 mw of power output, it is as powerful as much larger portable units and argon lasers, and has more then twice the power output of any other handheld ALS. The UltraLite ALS has an ergonomic design that will allow the user to comfortably use the ALS for long periods of time.
