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.
用精密澆注法生産超薄光學透鏡是省工省時的生産新工藝。
On the basis of thin-lens focal length measurement experiment, the imaging law of refraction-reflection system was further studied.
在薄透鏡焦距測定實騐的基礎上，進一步討論了折射反射系統成像的槼律。
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).
我一般選擇最高級的防輻射鍍膜鏡片，竝且挑選中薄的（我的個人騐光処方上槼定最薄最輕的鏡片）。

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.
