3M公司推出一系列新的光学缺陷自动定位器,它们能够在标准的波段内对有缺陷的点进行快速定位。这些仪器的工作波长分别为850、1300和1550nm,它们既适合短距离的应用,也适合远距离的应用。这些定位器与光学通讯系统的终端连接,使用方便。在出厂前,它们的探测阈值已被预调到了分贝,但用户可通过手动方法在0.5～6分贝范围内任意调节。通过一个自 3M has introduced a new line of automatic optical defect locators that quickly locate flawed points within a standard band. Operating at 850, 1300 and 1550 nm, respectively, these instruments are suitable for both short-range and long-range applications. These locators are connected to the terminals of the optical communication system and are easy to use. Their detection thresholds have been pre-set to decibels at the factory, but users can manually adjust them in the 0.5-6 dB range. Pass a self
