UV Borescopes — Ultraviolet Inspection Cameras for Leak Detection | Ralcam
Make the invisible obvious. Ralcam UV borescopes add ultraviolet illumination to a 4-way articulating probe, so fluorescent dye traces and surface-breaking cracks light up where white light shows nothing.

Fluorescent penetrant and dye-trace methods work brilliantly — on surfaces you can reach with a handheld UV lamp. The moment the area of interest is inside a bore, a weld cavity, or a sealed circuit, the standard method stops working. A UV borescope carries the light source in with the camera.
Applications
Weld and crack detection under fluorescent penetrant, refrigerant and coolant leak tracing with UV dye in HVAC and automotive circuits, and hydraulic system leak location where the joint is buried in an assembly.
Current specification
This is a focused, professional-tier range rather than a broad one. The M608U pairs UV illumination with 4-way articulation, an 8.5 mm probe on a 1 m cable, a 5" screen, and a detachable probe assembly — built for NDT and MRO work where the inspection has to be recorded, not just performed.

FAQ
What is a UV borescope used for?
A UV (ultraviolet) borescope makes fluorescent penetrant dye glow, so hairline cracks, weld defects and leaks that are invisible under white light stand out clearly. It's used in NDT, aerospace and engine crack detection. Ralcam's M608U and N508U are the UV models.
Do I need special penetrant dye, and is it included?
UV crack detection works best with a fluorescent penetrant dye applied to the surface. Check each product page for what's included; if dye isn't in the box, any standard fluorescent penetrant made for UV inspection will work.
Can a UV scope also do normal inspection?
Yes — UV models also carry white LED lighting for standard visual inspection, so you get both a normal view and UV crack detection in one tool. Switch lighting modes depending on the task.
