          Bar light illumination techniques

          Bar lights can be used to apply a strip of light along a target edge. Depending on the angle 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.

          Imaging examples

          Plastic parts on a conveyor

          With standard lighting

          The edges of the plastic part are unclear.

          With bar lights

          The edge has a high contrast and is clearly defined.

          Food packaging best before date

          With standard lighting

          Hotspots occur due to the target shape.

          With bar lights

          Uniform illumination of the print is possible.

          Connector pins

          With standard lighting

          There is no contrast between the terminal tip and the connector’s moulded surface.

          With bar lights

          Only the connector tip is highlighted.

          Bar light intensity distribution (typical)

          The above image displays the relative brightness across a multiple point grid for the CA-DB Series. Although the intensity varies with each model type, the associated illumination distance and relative brightness across the area are consistent. The brightest areas (shown in red) are considered 100% relative intensity and the dullest areas (shown in green) are considered 0% relative intensity. The images display the intensity differential across the area. By comparing the changes in the intensity differential for different degrees of diffusion, the ideal lighting range can be realised with the relative brightest points being 100%.

          * The above data are representative examples. This is not a guarantee of the product quality.
          * LWD is the distance from the illumination to the measurement target.
          * The above data was obtained without a diffusion plate unless indicated otherwise.
