The 77722 Motor Driven Variable Slit Assembly is designed exclusively for the MS257 monochromator. It uses a micro stepping motor to control a slit width range of 4 μm to 2.0 mm. Slit height is 15 mm. The slit width can be set using the Hand Controller, by computer, or automatically by the MS257 in order to have a predetermined and constant bandpass. Entire scans can be taken with the slit widths automatically adjusted by MS257 at each data point. Factory recalibration service is recommended when transitioning to this motorized slit assembly on the MS257.


77722电机驱动可变狭缝组件是专为MS257单色器设计的。它使用一个微型步进电机来控制狭缝宽度范围的4μm 2.0毫米。狭缝高度为15毫米。可以使用手动控制器、计算机或MS257自动设置狭缝宽度，以获得预定的恒定带通。整个扫描可以使用每个数据点上MS257自动调整的狭缝宽度进行。在向MS257上的电动狭缝总成过渡时，建议使用工厂重新校准服务。
