发明名称 Projection lens
摘要 <p>A lens assembly comprising seven lenses. Each lens includes u greater than or equal to about 12.8°, LEP equal to or from about 100 mm to about 400 mm, sigmaRba greater than or equal to about 1°, and sigmaRbi less than or equal to about -14°. The outward ray angle slopes and the inward ray angle slopes are positive if the outward ray and the inward ray intersect the optical axis at a location which, when seen from the object, is in an opposite direction to projection. The outward ray angle slopes and the inward ray angle slopes are negative if the outward ray and the inward ray intersect the optical axis at a location which, when seen from the object, is in an opposite direction to projection.</p>
