Using an additional reflection chamber the light is not emitted directly from the light source onto the object via the semi-transparent mirror, delivering a much more homogeneous illumination.
The following examples show printed foil packaging which is highly reflective and has a significantly varying profile. Using advanced coaxial light provides a very even illumination with mini mal highlights.
This type of illumination is suited for uneven surfaces that have a more pronounced profile such as wrinkled paper, foils, threads of screws, PCBs with soldered components, moulded plastics etc. Using advanced coaxial light provides a very even illumination with minimal highlights.
