Swing-Prism Borescopes with Rotatable Probe Shafts
Types PR and PRZ swing-prism rigid borescopes with variable direction of view, focussing device, rotatable objective tube and optional variable magnification zoom eyepiece. These instruments provide the capability to view steplessly in a range of directions from 55° fore-oblique to 115° retro-view. One instrument can therefore fulfill the function of two or three separate conventional borescopes.
This multiple viewing capability is further enhanced by the rotatable insertion tube which provides 340° of rotary scanning stop to stop.
This versatility allows the same scope to be used for multiple applications and thus can reduce the inspection time by removing the need to stop the inspection to change scopes.
Henke-Sass, Wolf swing-prism borescopes are available in three diameters, 6, 8 and 10 mm. On all models two alternative fields of view are available, the standard 50° FOV being supplemented by an optional narrow-angle 35° FOV giving higher magnification.
On all instruments an optional variable magnification zoom eyepiece can be selected.
With this option the instrument becomes probably the most versatile rigid borescope available today, having variable direction of view, variable focus, variable magnification and 340° rotary scanning.
