LUCEO 适用范围 水晶，玻璃，石英，树脂等透明光学材料 型号 LSC-5000B 重量 40KG 加工定制 否 光学元器件的材质不均一性，通这视光观察方法可以检测的设备。 光学元器件的不一均一性大体上有脉理，异物，气泡等，但是后期的研磨加工等同样会带来表面的不平整，或是表面划道等。 此设备是专门用于这些缺陷的检查检测的。 此设备将水晶板，玻璃等透明体内部的脉理及表面的研磨纹理可视化，视野范围大约在φ45mm，低通滤波器用的水晶板，蓝色滤光片等产品最为合适。 采用专门开发的软件，可以将设备本身的观察镜头所带来的影响降到最低，使检测背景列清淅，检查更容易。 折射率变化的可视化设备有观察方法称为纹影法，但观察LSC-5000B的方式采用阴影图形方法。通过在边缘产生的干扰，减少图像边缘模糊。 检测方法 阴影图形法 观测范围 Φ４５ｍｍ 光源 高辉度LED 波长450-465nm 有效画素 1360*1040 画素尺寸 4.65×4.65 μm OS Windows 7 / Windows 8 软件 ClearBack。不知道连接的图片里能不能看到，我尽力了。<br /> </td></tr></table> </div> <div id="comment_1205732" class="cm"> </div>
