The LBTEK Siemens Star Target, commonly referred to as a sun target or sector target, is used to test the resolution of imaging systems. Each sector of the Siemens Star Target tapers toward the center at a known angle, with a blank circle of 200 μm diameter at the center that interrupts all sector bars. By observing the changes in the distance of the sectors as they approach the center of the pattern, customers can define the resolution of the optical system and evaluate it in vertical, horizontal, and other directions without repositioning the test target. The LBTEK Siemens Star Target is widely used for assessing the imaging quality of optical systems, identifying focus errors, astigmatism, and other aberrations present in optical systems. Additionally, LBTEK offers customization services for resolution test targets. For other requirements, please contact LBTEK Technical Support.
