They are used primarily to check for burring in automotive fuel injection parts after machining. Because these inspections are a regular part of production line operations, borescopes need to combine excellent image quality with robust durability and minimal repair downtime. By introducing a modular structure for its new mini borescopes, Olympus has responded to user demand for improved durability and usability.
These systems consist of the main unit, the light guide (for attachment to a cold light source) and the eyepiece (for eyeball observation or camera connection), all of which are removable. Thanks to this modular structure, they can be configured for a wide range of uses by adding different eyepieces and scopes with different diameters and lengths. When repairs are needed, modules can simply be replaced.
To strengthen the bend resistance of the insertion tube, the material thickness has been increased by over 50% compared with earlier products without any increase in the outer diameter of the scope. The impact resistance of the distal end has also been enhanced through the use of tough sapphire glass.
A newly designed protective sheath (optional) can also be added. They provide tough protection over an extended area, from the base of the insertion tube to the distal end.
