optical zoom ratio

常見例句

The design results prove that the zoom system has high optical transmission, large zoom ratio, high resolution, small size and excellent image quality.
設(shè)計(jì)結(jié)果表明，該系統(tǒng)具有透過率高、變倍比大、分辨率高、體積小、像質(zhì)高等優(yōu)點(diǎn)。
Firstly, the zoom ratio may be enlarged. Secondly, the image point movement may be easily eliminated. The principle of optical compensated step zoom lens is explained.
這種變焦距物鏡有兩個(gè)優(yōu)點(diǎn)，一是可以實(shí)現(xiàn)高倍率變焦，二是容易消除在變焦過程中產(chǎn)生的像點(diǎn)移動(dòng)現(xiàn)象。
