A method for characterizing longitudinal chromatic aberration of microscope objectives using a confocal optical system
نویسندگان
چکیده
We describe a novel method of characterizing the longitudinal chromatic aberration of microscope objectives by recording a series of axial responses as a function of wavelength as a plane reflector is scanned through the focal region of a confocal microscope. Measurements are presented for a variety of objectives with differing degrees of correction. The use of the chromatic focal shift to measure surface profiles is also discussed.

The development of electron-optical techniques for geometric and chromatic aberration correction have significantly improved the spatial resolution of transmission electron microscopy (TEM) and enhanced its capability for chemical mapping [1].

متن کاملChromatic confocal microscopy for multi-depth imaging of epithelial tissue
We present a novel chromatic confocal microscope capable of volumetric reflectance imaging of microstructure in non-transparent tissue. Our design takes advantage of the chromatic aberration of aspheric lenses that are otherwise well corrected. Strong chromatic aberration, generated by multiple aspheres, longitudinally disperses supercontinuum light onto the sample. The backscattered light dete...
متن کاملControl of chromatic focal shift through wave-front coding.
Control of chromatic aberration through purely optical means is well known. We present a novel, to our knowledge, optical-digital method of controlling chromatic aberration. The optical-digital system, which incorporates a cubic phase-modulation (CPM) plate in the optical system and postprocessing of the detected image, effectively reduces a system's sensitivity to misfocus in general or axial ...
