Excentriciteten hos en cementerad lins h\u00e4nvisar till felinriktningen mellan den optiska axeln och linsens geometriska centrumaxel. M\u00e4ngden excentricitet uttrycks vanligtvis i vinklar, s\u00e5som 30 sekunder (30\u2033) eller 1 minut (1\u2032). Den st\u00f6rsta skillnaden mellan de tv\u00e5 ligger i deras inverkan p\u00e5 det optiska systemets prestanda.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

    • En lins med 30\u2032 excentricitet har en mindre avvikelse av den optiska axeln j\u00e4mf\u00f6rt med en lins med 1\u2032 excentricitet, vilket orsakar f\u00e4rre aberrationer. Dessa aberrationer inkluderar sf\u00e4riska aberrationer och kromatiska aberrationer av axeln.<\/li>
    • Ett objektiv med 1\u2032 excentricitet orsakar mer betydande aberrationer, vilket p\u00e5verkar bildkvaliteten. Till exempel \u00e4r sf\u00e4riska aberrationer och kromatiska aberrationer av axeln mer uttalade, vilket leder till allvarligare bildf\u00f6rvr\u00e4ngning.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
