Quality Test & Inspection: See the Difference with Borescopes
Borescopes inspect where technicians can't.
An optical instrument used for inspection work where the area to be inspected is inaccessible by other means, borescopes can be rigid, flexible and semi-rigid. A rigid borescope has an eyepiece on one end and an objective lens on the other linked together by a lens relay system. Flexible and semirigid scopes use fiber optics, instead of traditional lenses, to relay images and transmit light.
