4mm Videoscope & 4mm Borescope

What are 4MM Borescopes?

4mm borescopes are just as they sound, a borescope 4mm in diameter. While the 4mm borescope (sometimes referred to as a 4mm videoscope) can vary in actual size ranging from 3.7mm to 4.5mm, the small variance, however, is negligible and provides no adverse impact on the inspection process. A standard borescope probe length for the 4mm diameter borescopes is 1.5 meters (4.9 feet) and available with or without articulation with up to 3 meters (9.8 feet) of working length.

Who uses 4 MM Borescopes?

Generally thought of as the “multi-adaptive” videoscope, the 4mm diameter borescope is the most popular diameter due to its functionality with diverse applications. A popular choice among aviation and aerospace, the 4mm borescope can easily navigate through small chambers. As many aerospace professionals can attest, when inspecting turbine blades there is often a minimum requirement of utilizing at least a 2-way articulating borescope, although many professionals prefer the 4-way or joystick articulating borescope systems. For optimal articulation, the 4mm articulating borescope enables the end-user to steer or manipulate the borescope tip by cable guiding the tip into the body of the borescope handle. Safe to say, with many versatility features for the inspection process, the 4mm flexible borescope like the P&W inspection kit paired with the Turbomeca borescope Guide tubes (or any of our GE borescope guide tubes) ensures a steady navigation for superior inspection quality.

In addition to aerospace and aviation, professionals in casting and manufacturing industries are also known to extensively utilize both the articulating and non-articulating 4mm borescopes. In fact, in the casting industry, the articulation can be used to help guide the borescope around a slight bend while inside the inspection area. With non-articulating borescopes, these systems provide the same borescope probe diameter and standard features such as adjustable LED lighting, image capture, and video recording; however, the probe tip is fixed in a straight view or fixed side viewing. Additionally, the non-articulating borescope, often the borescope of choice, offers an economical solution where there is a high expectancy of borescope damage.

Visiting our 4mm Borescope camera options means that you are considering moving forward with the project. The 4mm portable videoscope is the most popular diameter for aviation borescope inspections. The slim diameter allows the videoscope probe to negotiate the guide tubes and get into those hard to reach places. Regardless of how you found our page we’re glad you’re here.
