5.2. Applications of 395nm UV Light
The 395nm UV wavelength is highly effective for detecting fluorescent substances. Here are some common uses:
- Detección de orina de mascotas: Detecta fácilmente manchas secas de orina de mascotas en alfombras, tapetes y muebles que son invisibles a simple vista.
- Autenticación de moneda y documentos: Verify the authenticity of banknotes, passports, and other official documents that contain UV security features.
- Detección de escorpiones: Scorpions glow brightly under 395nm UV light, making them easy to spot in dark environments.
- Inspección de minerales y piedras preciosas: Identify certain fluorescent minerals and gemstones.
- Curado de resina: Accelerate the curing process of UV-sensitive resins and glues.
- Bed Bug Detection: Locate bed bugs and their eggs, which may fluoresce under UV light.
- Inspección de higiene: Revela manchas ocultas y áreas antihigiénicas en habitaciones de hotel, baños y cocinas.

5.4. 395nm vs 365nm UV Light
While both 395nm and 365nm UV lights are used for fluorescence, they have different characteristics:
- 395nm UV (Alonefire SV103): This wavelength is more visible to the human eye, producing a noticeable purple glow. It is excellent for general detection of fluorescent materials, such as pet stains, currency, and scorpions, where a strong visual indication is desired.
- 365nm UV: This wavelength is closer to the true "black light" spectrum, emitting less visible light and more pure UV. It is often preferred for professional applications requiring minimal visible light interference, such as forensic analysis, specialized mineral identification, and some industrial curing processes.

Under 365nm UV, the same minerals exhibit a more vibrant and distinct fluorescence, indicating the difference in their applications.
6. Mantenimiento
- Limpieza: Limpie el cuerpo de la linterna con un paño suave.amp Paño. No utilice limpiadores abrasivos ni disolventes.
- Cuidado de la lente: Gently clean the UV lens with a lens cleaning cloth to remove dust or smudges. Avoid touching the lens with bare fingers.
