Fluorescent inspection is a critical step in industries such as aerospace, automotive, manufacturing for non-destructive testing (NDT) and quality assurance. A high-quality UV torch provides reliable illumination at the correct wavelength (UV-A, 365 nm), ensuring fluorescent dyes and penetrants can be seen clearly.
In this guide, we’ll look at what makes a UV inspection torch effective, what to consider before buying, and introduce some of the professional-grade UV torches we supply.
What to look for in a UV inspection torch
When choosing a UV torch for fluorescent inspection, there are several key factors to keep in mind:
- UV irradiance – Typically measured in µW/cm², sufficient output is required to meet industry standards.
- Wavelength – Most inspections require UV-A light at 365 nm. This ensures optimal fluorescence of dyes without excess visible light.
- Beam uniformity – A consistent beam ensures no dark spots or uneven illumination across the inspection area.
- Portability and battery life – Lightweight, rechargeable models are ideal for field inspections or hard-to-reach areas.
- Compliance and certification – Always ensure your UV torch complies with relevant NDT and safety standards.
