thin lens

基本解释

Using precision casting method to produce ultra-thin lens is a new manufacturing technology which saves both labour and time.
用精密浇注法生产超薄光学透镜是省工省时的生产新工艺。
On the basis of thin-lens focal length measurement experiment, the imaging law of refraction-reflection system was further studied.
在薄透镜焦距测定实验的基础上，进一步讨论了折射反射系统成像的规律。
Generally I pay for the highest level of non-glare coatings and I usually pick the middle of the thin-lens options (my personal prescription rules out the thinnest, lightest lenses).
我一般选择最高级的防辐射镀膜镜片，并且挑选中薄的（我的个人验光处方上规定最薄最轻的镜片）。

Both models maintain their slim profiles by incorporating an ultra-thin 4x optical zoom lens with folded optics.

Despite the 22x zoom lens, the camera was very thin and light -- it should be able to tuck into a pocket just fine.

So... hyperbole aside, the FX30 is thin and features a 3.6x LEICA DC VARIO-ELMARIT optical zoom lens, 7.2 megapixel CCD, Mega OIS optical image stabilization, Venus Engine III image-processing for shooting at ISO 1250, and a 2.5-inch 207k pixel LCD (the L74 throws down 230k pixels) with "Power LCD" to boost brightness by 40% (at the expense of battery life) when outdoors.
