However, finding the target area (especially with eye optics) and imaging it is easier due to special lenses and large LCD of the handset.

然而，找到目标区(特别是利用光学仪器)并成像就要靠手柄的特殊透镜和大型的液晶显示屏了。

The perfect focusing concept is proposed in lenses made of Left handed materials (or negative index materials) by means of geometrical optics.

从几何光学理论证明了，在左手系材料（负折率材料）透镜中存在完善聚焦的概念。

However, the appearance of the barrel of such optics with modified lenses does not have been changed.

然而，外观每桶改良等光学镜头并没有被改变。

The entire camera assembly includes everything you see below, which includes the clear optics (lenses), actuator (second black module from the left), sensor, and the black piece-parts that hold everything together.

The small size of the LED light chip allows another advantage arising from the physics of optics: Engineers can employ collaterally small lenses making it possible to efficiently extract, direct and focus the lumens, achieving useful illumination with far fewer lumens--and far less energy--wasted.

Medieval scholars were particularly fascinated by the science of optics and invented eye glasses partly as a result of their studies using lenses to determine the nature of light and the physics of sight.
