激光变形镜

详细介绍

激光变形镜

波前校正镜

我们提供灵活的模块化自适应光学系统有19 - 109控制通道，镜孔径15 - 50 mm。变形镜在激光应用程序可以涂上裸露的金属，如铝、银、金。我们也生产变形镜在高功率激光的应用程序。这些镜子特点99.99%的反射率在一个选择的波长。我们也提供超快速激光变形镜，有98%的宽带金属/电介质涂料550 - 1000 nm,集中在800nm。UV-enhanced可以涂上保护铝层、优化了266到350纳米的范围。其他类型的涂料可以定制。OKO激光变形镜检测固体激光器的谐振器，光学载荷高达40千瓦。

我们提供的系统使用压电变形反射镜 (PDM)和微型机械变形镜(MMDM)。FrontSurfer波前控制系统作为波前传感器和AO反馈控制器。

波前传感器

波前传感器系统包括:

·FrontSurfer独立的软件为Windows或Linux。程序重建波前从一个光斑图获得在六角形，正交或随机Hartmann(-Shack)面镜有任意数量的子孔径。该软件在Windows和Linux支持标准视频接口。在“对齐"模式下的软件能够实时动态显示低阶像差在极坐标下或相关格式。在反馈模式，程序连接OKO变形镜可用于低成本的实时自适应光学。

· FrontSurfer校准哈特曼面镜六角和正交几何图形，设计使用1/2英寸CCD阵列。可以提供作为一个独立的组件(正方形10 x10mm)或在一个C-mount兼容的头。

·广泛的显微镜头阵列为Hartmann-Shack传感器。可以提供独立的每个数组，波前传感器，或者安装在一个C-mount兼容的头。

· FrontSurfer -兼容的HR CCD和CMOS相机有电脑视频接口为Windows和Linux操作系统。

微透镜阵列

我们提供高质量的复制微透镜阵列专门为使用FrontSurfer波前传感器。作为一个标准的选项，我们提供一系列六角形的127微透镜有18毫米的焦距和一个300µm的距， C-mount安装。此外，我们还提供了一系列微透镜阵列的制作在玻璃和石英有小的数值孔径和99%光学填充因数。微观结构提供光谱效率(紫外到远红外)，机械和热稳定性。这些数组工作有非常高的光学载荷。提供一个有成本效益的解决方案，所有列出的数组可以被复制在塑料系列。微透镜阵列有正交或六角形的安排是可用的。
