zoom ratio

基本解釋

Compared with the traditional zoom system, this type of zoom system structure is easier to obtain high zoom ratio.
與傳統(tǒng)變焦距系統(tǒng)相比，該變焦距結(jié)構(gòu)形式較容易實現(xiàn)高變倍比變焦。
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優(yōu)點，一是可以實現(xiàn)高倍率變焦，二是容易消除在變焦過程中產(chǎn)生的像點移動現(xiàn)象。
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。

There's a 0.8-25x zoom ratio (36.3-2, 007mm 35mm equivalent), giving you quite a bit of range for viewing and recording just about any scene.
