The Schneider Group, (Bad Kreuznach, Germany) introduces the MacroVaron 85mm f4.5 lens featuring Schneider-Kreuznach's new Continuous Aberration Suppression (CAS) technology. The new MacroVaron lens (MRV 4.5/85 CAS 0.5X-2.0X) enables system integrators and equipment manufacturers to significantly improve the reliability and flexibility of quality assurance processes in production inspection systems. Schneider-Kreuznach's unique CAS technology within the lens enables the use of ultra-high-resolution down to 2.5 microns over an extremely large magnification range from 0.5X to 2.0X, with uniform performance over the entire range. A 62mm image circle, low distortion and excellent chromatic correction make the MacroVaron lens ideal for high-resolution line scan applications up to 12k (and down to 5-micron pixel sizes), such as those used in flat panel display (FPD) and printed circuit board (PCB) inspection systems. The relative illumination of the lens is virtually constant over the entire image height, enabling the use of the full size of the sensor. This uniformity of light eliminates the need for electronic compensation, thus minimizing the noise of the camera signal. The 85mm focal length of the MacroVaron lens reduces the required working distance, which decreases the space needed for the camera-lens assembly.Like all Schneider-Kreuznach industrial macro lenses, the new MacroVaron lens features Schneider-Kreuznach's unique iris locking mechanism and robust design, to ensure extremely reliable and precise measurements in even the harshest high-vibration manufacturing environments. www.schneiderindustrialoptics.com
