With bright field illumination (see also direct incident light), the camera is positioned exactly in the direction of reflection of the light rays and detects smooth surfaces particularly clearly, because the rays are reflected back in their original direction on smooth surfaces. An example of bright field illumination is coaxial illumination, in which the illumination […]
Coaxial lighting is diffuse incident light or bright field lighting. The light of an LEDsurface illumination is coupled laterally via a semi-transparent mirror into the beam path of a camera and projected onto the test object. This ensures that the test object is illuminated very evenly and without shadows. The light from the test specimen […]
