●Business card
(2) Objects with gloss but uneven surfaces
Only the flat portions of the object will shine, while other areas will appear as images without contrast.
●Wire
●Screw
2. Suitable applications for coaxial illumination:
Coaxial illumination is suitable for objects with gloss and flat surfaces.
It is suitable for the following examples:
●Metal plating
●Silicon wafer
●Substrate gold electrodes
