2、微透镜的用途主要是什么?（如哪些领域，可产品用过这东东？）<br /> 3、目前国内哪些厂家能做的好，做得量大？<br /> 4、其加工设备与小透镜加工设备有何不同？哪有这种设备购买？<br /> <br /> 呵呵 ，问题一箩筐，请先<img src="static/image/smiley/default/em27.gif" smilieid="56" border="0" alt=""

怎么不对，微透镜阵列同样可用钻石车床车出来。但是跟二元光学元件一样，在工艺上也是有限制。</div> <div class="postmsg">微透镜阵列一般是用在照明、投影系统的配光上，可使配光照度均匀，常用注塑压模的方法制作。<br /> 面型也可以是非球面，这类系统精度一般要求不是很高。<br /> 至于其他的，比如说光纤、光波导连接的微透镜制作方式就很多了，微加工、光刻..<br /> 还有一种可变焦的微透镜是用液晶或者其他导电溶液与薄膜和基底一起填充的，透镜内部呈液态。</div> <div class="postmsg">请问微透镜的形状检测都有什么方法？谢谢！</div> <div class="postmsg">各位回答比较混乱啊。<br /> 1.微透镜一般指尺寸毫米以下的。<br /> 2.不一定是塑胶镜片，理论上任何光学材料都可以。塑胶镜片是其中一种。<br /> 3.加工方式有很多种，各有优缺点，适用于不同的用途和需求。<br /> 4.微透镜阵列是多个微透镜的组合，透镜单元可以是各种需要的结构。<br /> 5.微透镜的理论应用范围很广，几乎涉及所有的应用工程，比如裸眼3D，LED二次配光，LED芯片等方面透镜的自清洁，光束整形，微结构散热，第三代薄膜太阳能电池等，只不过应用上受其他配套技术，加工技术和价格等各种原因影响。</div> <div class="postmsg">微透镜一般做成阵列，孔径在几百微米以下，主要分为折射型和衍射型的微透镜。折射型的微透镜和普通透镜一样，衍射型微透镜其实就是菲涅尔透镜，由于加工工艺的原因一般做成多元位相浮雕结构。材料可以根据使用波长的不同来选择不同材料，比如紫外用GaN。主要和探测器一起使用，用于提高探测器填充因子，来提高其探测率，这种微透镜阵列和探测器结合的技术在红外上运用比较成熟。</div>
