LST400激光快门
LST400激光快门型号设计用作激光安全联锁装置并适用于各种加工应用。该型号标配提供开启和关闭状态的TTL输出位置传感器。其薄型机身和8毫米孔径兼容多种主流激光源。兼容的系统控制器为CX4000B或基于24 VDC的用户自建电路。产品选项通过后缀代码系统进行选择。请注意，许多选项在生产后无法加装，请仔细选择。
选择后缀 -C2 用于CO2激光应用（请参阅LST400-C2）。
选择后缀 -IR 用于约700 nm起始的红外应用。此选项将标准镀铝反射镜更换为金镜。
标准镀铝反射镜适用于深紫外至约700 nm波段（请参阅LST400-AL）。
针对OEM应用，可提供特殊介质膜反射镜（请参阅LST400-123或LST400-4）。
电缆选项也可提供，详情请咨询。
使用本型号需特别注意：
热安装要求： 如果光学功率耗散接近额定值上限，必须高度重视散热安装。
