Testing the quality of objectives for microscopy and smartphones
Lens assemblies for mobile devices and microscope objective lenses are designed to generate sharp images not only in the centre of their field of view, but also off-axis, at field points. Measuring the imaging quality of lens assemblies is realized by measuring the wave aberrations on the optical axis and in the field. Furthermore, automated measurement procedures provide information about focal length, chromatic aberration, polarization effects, PSF and MTF.
