Ordinary UV LED flashlights, even those with peak wavelength as low as 365 nm, will emit a significant amount of visible wavelengths. However, the TrueBlack longwave flashlight kit offers the perfect solution for when you need to eliminate such unwanted visible wavelength contamination and achieve superior visual clarity. This pre-assembled kit combines a high-brightness UV flashlight with a high-quality UV-transmitting glass filter (Hoya U-325C), captured with an impact-resistant vinyl cap. Great for photography and detecting low-level fluorescence. Applications include crime scene photography, SmartWater® visualization, fluorescent minerals, vaseline glass, ethidium bromide gel documentation, leak detection, document authentication, stain detection, counterfeit bill detection, scorpion hunting, etc. SmartWater is a registered trademark of SmartWater Limited.
