The second outer coaxial light source lens assembly 84 is identical in structure to the first outer coaxial light source lens assembly 82.

The inner coaxial means that the light beam falls on the observed object through the lens in the objective lens, and the outer coaxial means that the light beam surrounds the outer side of the objective lens and falls on the observed object. Typically the inner coaxial is a point light and the outer coaxial is a ring light. The coaxial light is mainly characterized in that the illumination angle and the optical phase angle are small, the light reflection is small, the observed object is clearer, and the coaxial light is mainly applied to transparent observed objects such as (wafers, LCD screens, CCD lenses, mobile phone cover plates, multimedia screens and the like). The scratches and stains on the transparent object cannot be seen by using the conventional side light source illumination, and the scratches or stains are difficult to distinguish because the reflection angle of the side light is not in a phase angle. External coaxial light also presents this problem because its angle and phase angle are not coincident (so it is difficult to detect micro-scratches within 0.01 mm). The scratch and the stain can be clearly distinguished by adding the inner coaxial light source lens component 83.

The glass cover plate of the mobile phone is reasonably divided into three areas, wherein the first outer coaxial light source lens assembly 82 is used for detecting one part of the frame part of the glass cover plate of the mobile phone, and the second outer coaxial light source lens assembly 84 is used for detecting the other part of the frame part of the glass cover plate of the mobile phone.
