What is a UV Torch?
A UV torch, also known as an ultraviolet flashlight, emits ultraviolet light, which is invisible to the human eye but reveals fluorescent materials. These torches are commonly used for detecting counterfeit money, checking for leaks, forensic investigations, mineral hunting, pest detection, and hygiene inspections.
Unlike standard torches, UV torches operate on specific wavelengths (usually 365nm or 395nm), which determine their effectiveness.
How to Choose a UV Torch
Selecting the right UV torch depends on its intended use. Here are key factors to consider:
1. Wavelength
- 365nm UV Light – The best option for professional use, as it produces minimal visible purple light and highlights fluorescence more effectively.
- 395nm UV Light – A more affordable option but may produce a stronger purple glow, which can affect visibility.
- 405nm UV Light – Typically used for specific applications like curing resins or identifying specific substances.
2. Light Output and Power
- Higher UV intensity allows for better fluorescence detection.
- Some models come with multiple UV LEDs for increased power.
3. Battery Type
- Rechargeable lithium-ion batteries provide the longest runtime and brightest output.
- AA or AAA batteries are more convenient for portability but may offer lower power.
4. Durability and Build Quality
- Aluminum or stainless-steel bodies ensure the torch is rugged and long-lasting.
- Water-resistant or impact-resistant designs are ideal for outdoor or industrial use.
