The condition for the ME-VAL is obtained from the paraxial ray equation rather than from axial focusing field expansions. The study shows that the ME- VAL also reduces the off-axis aberrations significantly, though not as much as its MM-VAL counterpart. A ME-VAL has been proposed for a magnetic objective lens using octopole deflector electrodes, in which the VAL condition is slightly mismatched. The results shows that the ME-VAL is less sensitive to mismatches in the VAL fields than the MM-VAL counterpart in terms of off-axis aberrations, and comparable performance can be obtainable if the advantages of electrostatic deflection can be fully exploited.","is_dataset_classified":null,"base_score":1.3862943611198906,"endowment":1.3862943611198906,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"18998783","pmcid":null,"openalex_id":"https://openalex.org/W1968449391","authors":[],"funders":[],"total_grants":0,"fwci":null,"citation_percentile":null,"influential_citations":0,"citation_trend":[{"year":2017,"count":1},{"year":2024,"count":1}],"oa_status":"closed","license":null,"oa_locations":[{"url":"https://doi.org/10.1117/12.370120","host_type":"journal"}],"fields_of_study":["Magneto-Optical Properties and Applications","Magnetic properties of thin films","Optical Coatings and Gratings","Engineering","Physics"],"mesh_terms":[],"keywords":["Electrostatic lens","Magnetic field","Deflection (physics)","Magnetic lens","Paraxial approximation","Physics","Optics","Lens (geology)","Deflection angle"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Affordable and clean energy"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-07-18T21:00:29.862721Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
