Bar Lights The addition of high-intensity models to KEYENCE's lineup of bar lights
CA-DB/CA-DBxW
Bar light illumination techniques
Camera/light arrangement
Bar lights can be used to apply a strip of light along a target edge. Depending on the alignment of the light and the camera, the bar light can be used to enhance or reduce specular reflection from a target. For highlighting a feature with specular reflection (such as the tip of a pin), the direct reflection of light has to come back into the camera. For removing specular reflection (sometimes referred to as hotspots), the direct line of reflection needs to be away from the camera.
High-intensity model equipped with micro lenses added to lineup
A high-intensity model equipped with micro lenses (CA-DBxW) has been added to the lineup. Compared to the white type, this model achieves a light intensity that is approximately four times that of the conventional model. * This model can provide high-intensity lighting over a wide area. Also, no screws are needed to fix the diffusion plate (included) of the high-intensity model in place, which eliminates concerns regarding the screws falling out due to vibrations.
