The CA-DR Series includes flat horizontally arranged LEDs, which help provide uniform intensity across a target. Six different sizes and colours of light with optional diffuse and polarising filters are available. Making the ring well suited to a wide variety of application and camera needs.
Light is reflected circumferentially according to the target profile. The target surface condition can be clearly seen.
You can obtain an image without halation by using the polarising plate.
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 realised with the relative brightest points being 100%.

* LWD is the distance from the illumination to the measurement target.
