Qioptiq Imaging Solutions Inc.’s Optem Zoom 125C, a microimaging variable-magnification lens system for the microelectronics, telecommunications, semiconductor and manufacturing sectors, features a 12.5:1 zoom ratio, top-end resolution of 300 line pairs per mm, a nominal working distance of 89 mm and a nominal magnification range of 0.52× to 6.5× in standard configuration. Compared with the previous model, the system achieves a 50% gain in illumination uniformity across the entire field of view at low magnification. Interchanging zoom modules with function modules allows application-specific configuration without tooling or a decrease in optical performance.
