Swing-Prism Borescopes

Borescopes with variable viewing direction, objective lens probe rotatable by 340°, focussing and optional zoom eyepiece for magnification allow inspections with continuous adjustment from 60° to 120°, and a second version from 10° to 115°, retrospective view. All settings are made on the eyepiece. Consequently, the instrument enables to carry out several inspection tasks in a flexible and fast way. Moreover, the viewing range is extended owing to the objective lens probe rotatable by 340°.
