凸透镜

The light source directs rays through a plane convex lens that focuses the light into a parallel beam. The light beam passes through the grid diaphragm, which splits it to produce a second beam of light 90° out of phase.

光源将光线照射到平凸透镜上，透镜将光线聚焦成平行光束，光束穿过光栅膜片，光栅将光束分离出第二根90度异相光束。

An optical element such as a rear projection screen for an image display device comprises at least two substantially rigid sheet members each having a first major surface and a second major surface providing a plane of incidence and a plane of emergence, respectively, through which light is transmitted sequentially. A first sheet member comprises a Fresnel lens, and a second sheet member comprises a lenticular lens array on each of the major surfaces thereof.

一种光学元件，例如用于图象显示装置的背投式屏幕（1），包括至少两个基本为刚性各具第一主表面（21；31）和第二主表面（22，32）的板部件（2；3），分别提供顺序穿过光线（10）的入射面和出射面，第一板部件（2）和第二板部件（3）在其各个主表面（31，32）上分别包含一个菲涅耳透镜（24）和一个双凸透镜阵列33，35。

Irradiation from a Q-switched Nd: YAG laser (pulse duration: 12 ns, repetition rate: 10 Hz) was focused onto the sample surface by a plano-convex lens with a spot diameter of about 1 mm to ablate a portion of sample and generate a micro plasma.

一个平凸透镜把斑直径大约为1 mm的光量开关Nd： YAG激光器（脉宽：12 ns；重复频率：10 Hz）辐照聚焦于样品表面，用来烧蚀样品的一部分，形成一个微等离子体。

Open Linear Encoder includes main grating scale and optical encoder head. This optical encoder head includes LED light source, optical detector module, and secondary phase-grating. LED light will pass through the plano-convex lens and produces parallel light. As the parallel light pass through secondary grating, the quadratic image display on the main grating scale. And the Moire interference will be reflected from the main grating scale and detected by optical detector module, as there is a relative shift between the main and secondary grating. From detecting the periodic sinusoidal signal with phase difference 90°, the period represents the grating pitch, using the counter to detect the number of periodic signals to get the displacement, and we can adapt the technology of electron subdivide further to increase the resolution of measurement .

反射式光学尺包括主光栅尺及光学读头，光学读头包含LED光源、光侦测器模组及相位式副光栅，LED光源经平凸透镜，产生平行光穿透副光栅后，副光栅之二次成像投射在反射主光栅尺上，当主、副光栅因相对运对产生之Moire干涉经主光栅尺反射至光电检测器，检出相位差90°之周期性弦波讯号，其周期代表栅距，因此可用计数器检出周期性讯号数目得到位移量，可进一步采用电子细分割技术提高解析度。

In our science the term galaxy refers to the lenticular star system that contains millions and millions of stars.

在我们的科学词汇里，星云系指的是凸透镜片型的星系，包含了千万以上的恒星。

According to range of the focal distance, dropping UV glue which is crystalline and unexpensive into lens cavity with UV rays, and then forms as soon as solidifies the convex lens. Combining UV curing glue convex lens and variable focus lens, the focal distance range achieves the 8.3~24.5 mm low focal distance effect.

於此之后根据变焦效果的需要，利用UV胶透光性佳、成本低，将UV胶滴定於透镜腔体中，形成一凸透镜，藉由变焦透镜与UV胶透镜结合，焦距变化达到8.3~24.5mm范围的低焦距效果。

Thick in the middle and thin at the edge, its shape is just like a huge convex lens. It is above and supported by seawater, rises and falls with the tides and accretes with seawater.

其形态中间厚，边缘薄，宛如一枚巨大的凸透镜，承托于海水之上，与潮汐同涨落，与海水相伴生。
