LED Lighting Vision System Peripheral Equipment CA-D Series
Coaxial Lights (Vertical)Coaxial vertical illumination emits light on the same axis as the camera and lens.
Coaxial light illumination techniques
The coaxial light transmits light from the side onto a half way mirror. The mirror reflects the light onto the target. Specular reflected light is allowed to pass back up to the camera whereas diffuse reflected light from the target is rejected. This in turn causes a contrast at the edge points of a target.
In addition, the further the light is from the target the greater the rejection of diffused light becomes, creating greater image contrast and definition.
