Lighting geometry:
Bright-field.
Diffuse source. Mounted on the sensor, with the lens axis through the center opening of the ring light assembly. Ring light illuminates the area directly in front of the camera.
Description: Provides diffused illumination over a small area.
The ring light is great at creating
contrast between
color differences in various parts. In applications with good color contrast, this is the light of choice.
