Rigid borescopes are particularly robust and designed for heavy-duty industrial use. With the HOPKINS(R) II rod lens system, they reliably deliver exceptionally clear, sharp, and bright images.
The so-called swing prism borescope features a swing prism at its tip. Using a control handle, the direction of view can be infinitely adjusted between 0A and 140A. The sheath can be rotated by 400A. The result is the largest field of view available on the market.
This Borescope diameter is 8 mm.
