The 71455 Shutter, with its compact size, easily integrates into a variety of light source systems. This shutter can be operated using the toggle switch on its case or by sending a TTL signal to the BNC connector. The shutter aperture is 0.4 in [10 mm] diameter. Its thin profile allows it to fit into a tight optical path. The shutter is designed with standard 1.5-inch series flanges, so it may be coupled to a wide variety of Oriel accessories and instruments. The #1/4-20 threaded holes on three sides of the housing allow it to be conveniently positioned when being rod mounted. The Oriel OPS series arc lamp power supplies and quartz tungsten halogen (QTH) lamp power supplies are capable of providing a TTL signal to operate the shutter. The light intensity control feature of the OPS power supplies allows users to set up timed exposures and control the dose received by the sample. These power supplies include command sets, allowing developers to design programs that can automatically control when the shutter is open or closed. The shutter receives power to operate from a small DC power supply, which is provided. It is shipped with both U.S. and European power cords. This shutter is used with light sources up to 150W; higher power requires a liquid filter or other means of heat control.

71455快门，其紧凑的大小，很容易集成到各种各样的光源系统。这种快门可以使用其外壳上的拨动开关操作，或者通过向BNC连接器发送TTL信号来操作。快门孔径为0.4英寸[10毫米]。它的薄轮廓使它能够适应一个紧密的光学路径。快门采用标准的1.5英寸系列法兰设计，因此它可以与各种各样的喇叭配件和仪器相结合。3侧螺纹孔#1/4-20允许安装杆时方便定位。Oriel OPS系列弧灯电源和石英钨卤素(QTH)灯电源能够提供TTL信号来操作快门。OPS电源的光强控制特性允许用户设置定时曝光和控制样品接收的剂量。这些电源包括命令集，允许开发人员设计可以自动控制何时打开或关闭快门的程序。快门从提供的一个小的直流电源接收能量来工作。它与美国和欧洲的电源线一起运送。此快门与150W光源配合使用;更高的功率需要液体过滤器或其他热控制手段。
