Describes a premium lens system that achieves apochromatic color correction while simultaneously flattening the focal plane. These lenses eliminate color fringing across a wide spectrum and maintain edge-to-edge sharpness, making them essential for high-resolution microscopy and precision metrology where focus drift across the field is unacceptable.
