Applications

The 365nm UV wavelength is highly effective for a variety of uses:

• Pet Urine Detection: Ideal for locating hidden pet stains on carpets, rugs, and other surfaces that are invisible to the naked eye.
• Mineral and Gemstone Inspection: Many minerals and gemstones fluoresce under 365nm UV light, making it useful for collectors and enthusiasts.
• Currency and Document Verification: Reveals security features on banknotes, passports, and other official documents.
• Stain and Leak Detection: Can be used to find leaks in HVAC systems or automotive fluids (when a fluorescent dye is added).
• Resin Curing: Suitable for curing UV resin in crafts and jewelry making.
