We will now be carrying an Ultra Thin HQ Borescope that will measure only 0.35mm in diameter. As our thinnest diameter fiberscope yet, this fiberscope will allow places with even smaller access points to be visually inspected. This .35mm borescope features the same German made high resolution Quartz Fibre optic bundle used in our other Ultra Thin HQ Borescopes. This HQ fiberscope also comes with a LED light source for bright illumination and a built in focus ring on the eye piece to ensure a clear crisp image every time. For more information on this new 0.35mm Ultra Thin HQ Fiberscope please contact any of our sales reps.
