Wide field of view objective lens assembly |
摘要 |
An objective lens assembly provides up to 60 degrees field of view for the ANVIS image intensifier goggle. A first lens subassembly positioned on the focal axis faces a external view and substantially corrects pupil aberrations in an aperture stop located after the first subassembly. A second lens subassembly is then located after the aperature stop on the focal axis. Color and field aberration corrections is provided while maintaining substantially high quality focus by a third lens subassembly. A lens element after the third lens subassembly on the focal axis flattens the image plane over the intensifier image format such that there results a format of up to 25 mm with a photocathode resolution for up to a 60 degree field of view.
