365nm UV Gun Applications
A 365nm ultraviolet light gun is a powerful inspection and curing tool designed to emit high-purity UVA light with minimal visible light interference. This wavelength is ideal for applications that require strong fluorescence response and precise UV activation.
In industrial settings, 365nm UV guns are widely used for UV curing of adhesives, inks, resins, and coatings, helping manufacturers achieve fast curing speeds and improved production efficiency. They are also essential for non-destructive testing (NDT), where the UV gun reveals cracks, leaks, or surface defects when used with fluorescent penetrants.
In quality inspection and maintenance, 365nm UV guns help detect oil leaks, coolant leaks, and contamination in automotive, aerospace, and HVAC systems. The strong fluorescence output makes hidden issues clearly visible. In forensic and security fields, these devices are used to identify counterfeit documents, invisible markings, and biological residues.
Additionally, 365nm ultraviolet light gun are popular in gemstone and mineral identification, as well as laboratory research requiring accurate UVA exposure. With their focused beam, high intensity, and portability, 365nm UV guns provide reliable performance for professional inspection, curing, and detection tasks across multiple industries.
