The 77721 Fixed Slit Holder may be mounted to the input port of an Oriel MS257 Spectrograph, or at the input and output ports of the Oriel MS257 Monochromator. Using fixed slits is the most economical choice when a single, non-adjustable height and width are required. Fixed slits should also be considered when a few select sizes are required, as they provide excellent repeatability. A number of fixed slit models are available in various sizes (ordered separately). When ordering fixed slits, the input and output slits should be of the same size. The MS257 Monochromator and Spectrograph require fixed slits to be installed into the 77721 prior to operation. The 

The MS257 Spectrographs and 77250 Manually Operated Monochromator require purchase of the 77721. Order two for single output port instruments, and three for dual output port configurations.

Note: fixed slits are slit holders ordered separately. The slits should be the same size at the instrument's input and output ports.

77721固定狭缝支架可安装在Oriel MS257光谱仪的输入端口，或安装在Oriel MS257单色仪的输入和输出端口。当需要一个单一的、不可调整的高度和宽度时，使用固定的狭缝是最经济的选择。当需要一些选择的尺寸时，也应该考虑固定的狭缝，因为它们提供了很好的可重复性。许多固定狭缝型号有各种尺寸(单独订购)。在订购固定的狭缝时，输入和输出狭缝的大小应该相同。MS257单色仪和光谱仪在操作前需要在77721上安装固定的狭缝。的MS257光谱仪和77250手动操作单色仪需要购买77721。单输出端口仪器订购2台，双输出端口配置订购3台。注意:固定狭缝是分开订购的狭缝支架。在仪器的输入和输出端口上，狭缝的大小应该相同。
