#CMT# #/CMT# The lens (1000) has an inner lens group (120) that is set with a positive subset (111) with a positive meniscus lens (20). An outer lens group (110) is set with a negative subset (112) having a negative meniscus lens (30). The glasses are arranged spatially in partial dispersion plane. The index of refraction for light of Fraunhofer lines, numerical control of index of refraction and index of refraction for light of wavelength are determined. The upper and lower limits of coherent spectral region of lens representing pure transmission are set to specific range. #CMT# : #/CMT# An independent claim is included for a lens assembly. #CMT#USE : #/CMT# Polychromatic corrected lens of lens assembly (claimed) for image sensor installed in camera. #CMT#ADVANTAGE : #/CMT# The manufacturing process of the polychromatic corrected lens can be simplified. The cost of the polychromatic corrected lens can be reduced. The extensive equality of diagram properties independent of concrete in each selected scale to user can be facilitated. The time consumption of polychromatic corrected lens can be reduced. The objects having equal image size with different scale in far spectral regions can be imaged effectively without depending on focus. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows the schematic view of the lens. 20,70 : Positive meniscus lens 30,60 : Negative meniscus lens 110,210 : Outer lens group 111,211 : Positive subset 112,212 : Negative subset 120,220 : Inner lens group 1000 : Polychromatic corrected lens. |
