UV Application

UV products primarily focus on 365nm (long-wave UVA) and 254nm (short-wave UVC).

The 365nm wavelength offers strong penetration and relatively higher safety, making it the preferred choice for most fluorescent applications; while 254nm is mainly used for sterilization and disinfection.

Residential and Commercial Applications

Detecting Cat Dander: Cat dander exhibits a fluorescent reaction under UV light.

Curing Adhesives: UV-curable adhesives rapidly transition from liquid to solid upon UV absorption.

Cleaning Inspection: Identifies hard-to-detect stains on bedding, carpets, and walls.

Industrial Inspection and Maintenance

Penetrant Testing: Used to detect microscopic cracks on component surfaces. When combined with fluorescent dye, cracks will fluoresce.

Leak Detection: In air conditioning and automotive repair, fluorescent dye is added to the system; leak points will emit a vivid fluorescent glow.

Equipment Maintenance: Used to inspect circuit board cracks, component aging, or the uniformity of specific coatings.

Anti-Counterfeiting Verification

Banknotes and Documents: Currency, passports, ID cards, and driver's licenses all feature specific UV security features, fluorescent fibers, and patterns.

Luxury Goods: High-end apparel, handbags, watches, and alcoholic beverages often incorporate invisible fluorescent anti-counterfeiting marks on labels and packaging to verify authenticity.

Research Observations

Mineralogy: Many minerals exhibit vibrant fluorescent colors under UV light, serving as a crucial method for identifying and collecting mineral specimens.

Biology: Observe the fluorescent phenomena of scorpions, certain fungi, plants, and even marine organisms (such as corals) under UV illumination.

Sterilization and Disinfection (UV-C 254nm)

Item Disinfection: Ideal for sanitizing small surfaces like phones, keys, and the inside of masks.

Pet Cleaning: Even after cleaning, urine stains left by pets like cats and dogs will fluoresce under UV light. UVC helps you achieve thorough cleaning.

Cautions

Avoid direct exposure to eyes and skin. Prolonged exposure to UVA radiation may also cause damage to skin and eyes.

When using UVC for sterilization, personnel and pets must leave the area. Do not direct the light toward humans.
