  These pen lights are specifically designed for inspections. They are mostly used in professional settings like forensic investigations, inspections, and counterfeit detection. They emit a concentrated beam of UV light. This light highlights and reveals various substances and materials like forensic evidence, UV-reactive dyes, and counterfeit currency.

• UVB Pen Lights

  These pen lights are specifically designed to emit UVB light. This is a type of UV light that has various applications in the medical field. They are mostly used in phototherapy for the treatment of skin conditions like psoriasis and vitiligo. UVB pen lights are also beneficial in dermatology for vitamin D synthesis.

Function and Features of UV Pen Light

A UV pen light has various functions, and its features include the following:

• Compact and lightweight

  UV pen lights are usually compact and lightweight. The compact and lightweight design enhances portability and ease of use. It makes the pen light easy to carry in pockets, purses, or tool bags for quick access when needed.

• Skinny design

  Most of the UV pen lights have a slim design. The slim design improves their accessibility in tight spaces. It makes them ideal for tasks that require precision detection in small or narrow areas.

• Metal construction

  UV pen lights are usually made out of metal. The metal construction improves their durability and longevity. It can withstand repeated use and impact and is often resistant to scratches and abrasion.

• UV wavelength of 395nm- 400nm

  The UV pen lights emit wavelengths between 395nm and 400nm. This wavelength is useful for various UV applications, such as detecting stains, counterfeit currency, or pet urine. It’s also used in curing UV resin and fluorescence.

• Easy to operate

  Most UV pen lights are easy to operate. They come with simple on-and-off functions. Some have a push switch at the rear or a removable clip at the front. This UV pen light is easy to use and control.

• Adjustable focus

  Some UV pen lights have an adjustable focus. The adjustable focus allows for light beam customization for different tasks. It provides a wide beam for large area illumination and a concentrated beam for precision detection.

• Water-resistant or splash-proof

  Some UV pen lights are water-resistant or splash-proof. The water-resistant or splash-proof feature improves the pen light's durability in different environmental conditions. It enables it to function well in wet or humid areas without damage.

Scenarios where UV Pen Light is used

UV pen lights are used in various industries and applications. Business customers looking to purchase these UV lights for resale purposes should note the following common usage scenarios:

• Forensic Investigations

  UV pen lights are used during crime scene investigations to detect and examine evidence. The lights are used to reveal bodily fluids such as blood, saliva, or semen, which may not be visible under normal lighting. UV lights are also used to find fingerprints, the latent prints often become visible when dusted with a special powder under UV light.

• Authentication of Documents and Currency

  UV pen lights are used in the verification of security features found on banknotes and important documents. The light exposes special inks and fibers embedded in currency notes and documents that glow when struck by UV light. This makes it easy to check the authenticity of currency notes as well as diplomas and certificates before they are presented at auctions.

• Art and Antique Restoration

  UV pen lights are often used in the examination of artworks and antiques. The light reveals hidden details on the surface of the items. For instance, UV light can expose cracks, previous restorations, and authentically details. This allows experts to determine the item’s condition and authenticity as well as to assess the extent of damage.

• Inspection of Insects

  Entomologists use UV pen lights to study and inspect various insects. For example, some insects are attracted to UV light, thus making it easier to capture and study them. Additionally, certain insects have body parts that glow under UV light. Consequently, the use of pen lights aids in the examination of these insects.

• Medical Applications

  UV pen lights are commonly used in dermatology. The doctors use them to identify skin conditions such as psoriasis, fungal infections and dermatitis. In dentistry, dental practitioners use UV pen lights to cure and seal dental resins. They also help in the detection of dental carries.

• UV-C Sanitation

  Some pen light types emit UV-C light that is used for disinfection and sanitation. The UV-C light kills or inactivates pathogens such as bacteria, viruses and microorganisms. This is done by disinfecting high-touch areas in public places like hospitals, offices, and restrooms.

• Preventive Veterinary Care

  Vets use UV pen lights for various applications such as the examination of skin conditions in animals, the detection of parasites and the assessment of oral health in pets. Regular veterinary checkups involve the use of these lights to ensure the overall health of pets.

UV Pen Light Q&A

Q1: Can we use an UV pen light to cure all types of resins and gels?

A1: No, the UV pen light cannot cure all types of resins and gels. Some resins are compatible with UV-A lights, while others require UV-C light. The latter are often used for sanitation purposes. Always check the resin manufacturer’s guidelines to get the suitable light type.

Q2: What safety measures should be taken when using a UV pen light?

A2: Users should wear UV-blocking sunglasses to shield their eyes from harmful rays. It’s also necessary to limit skin exposure to the light and use the pen in well-ventilated areas, particularly when working with UV-sensitive chemicals.

Q3: How long should someone hold a UV pen light over a pet stain to detect it?

A3: There’s no specific time duration because the light should be moved slowly over the area that needs to be checked. A thorough sweep is more effective than holding it in one spot.
