ActiveImage measurement method for numerical aperture of microscopic objective
显微物镜数值孔径图像式测量方法
Application Summary AI generated
This standard specifies an image-based measurement method for determining the numerical aperture (NA) of microscope objective lenses, using captured image data to calculate the NA value. It is applied in the quality control, calibration, and performance verification of optical microscopes within industries such as semiconductor inspection, biomedical imaging, and materials science. The method provides a non-contact, automated alternative to traditional mechanical or optical bench measurements for objective lenses used in precision microscopy systems.
