          Ring light illumination techniques

          The CA-DR Series includes flat horizontally arranged LEDs, which help provide uniform intensity across a target. Six different sizes and colors of light with optional diffuse and polarizing filters are available. Making the ring well suited to a wide variety of basic application and camera needs.

          Application

          Plastic bottle

          Ring light only

          Light is reflected circumferentially according to the target profile. The target surface condition can be clearly seen.

          Ring light + polarizing filter

          An image can be obtained without halation by using the polarizing plate.

          Ring light intensity distribution (typical)

          The above image displays the relative brightness across a 10000 point grid for the CA-DR 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 lighting heights (LWD) the ideal lighting range can be realized 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 inspection target.
