Edmund Optics has introduced TechSpec spherical aberrationcompensation plates optimized for use in collimated light with small fields ofview. Leveraging a precision BK7 substrate, these ...
THE steeply curved surface of the field lens of a Kellner-type eyepiece usually introduces considerable spherical aberration of the principal rays. Frequently, this aberration cannot be corrected ...
Scientists at the Research Centre Julich in Germany have made individual oxygen atoms in perovskite materials directly visible using an electron microscope. Their success relies upon the development ...
Until recently, electron microscopy’s main engineering constraint has been spherical aberration of the objective lens - a feature of all round lenses that causes image distortion. Not only has ...
Two new Olympus TruResolution objectives for multiphoton laser scanning microscopes deliver an industry-first automatic spherical aberration compensation function that also compensates for Z-shifts ...
The latest aberration-corrected electron microscopes can resolve individual atom columns in a silicon crystal that are just 78 pm apart. How many students are told, perhaps during their first science ...
BERKELEY, CA -- TEAM 0.5, the world's most powerful transmission electron microscope -- capable of producing images with half-angstrom resolution (half a ten-billionth of a meter), less than the ...
One of the oldest problems in optics has been solved. Rafael Gonzalez from Mexico's Tecnologico de Monterrey has come up with an almost comically dense equation that can be used to almost completely ...
Applying aspheric treatments to cataract and refractive surgery procedures can significantly reduce spherical aberration and the consequent effects of glare and haloes, improving postoperative visual ...
