The word “borescope” is an umbrella term for the visual inspection tools that capture live video footage of the spaces they’re inspecting. There are a variety of borescope models available to suit your specific needs. For instance, rigid borescopes are often used when straight-line access to a targeted viewing area is required. These kinds of borescopes use a lens system to send images back to the viewer in real-time. An angled mirror and eyepiece make it easy to get a close-up view of the equipment you’re inspecting.
