Visual and Optical Testing is one of the essential inspection method of non-destructive testing. In Visual Inspection, the probing medium is light the portion of the electromagnetic spectrum with a wavelength of 380-770 nm that is capable of exiting the human retina. Visual testing requires adequate illumination of the test surface and proper eye-sight of the person performing this inspection.

Visual Testing is performed as direct visual testing, remote visual testing and translucent visual testing. Various mechanical and optical aid such as mirror, magnifier, bore scope, fiber scope and videos scopes are used when human eye get limitation. Light lens systems such as bore scopes and fiber scope allow remote surfaces to be examined which permit the introduction of the device into very small access holes detect minor discontinuities and most of the equipment is capable to make permanent record also.
