The 77218 Fixed Slit has a 0.12 mm width and 18 mm height and is the most economical choice if only a few slit sizes are required.. They also offer the greatest accuracy and repeatability. This precision slit is fixed onto a machined block that slides into the 77294 Fixed Slit Holder. The Fixed Slit Holder is ordered with the Oriel monochromator or spectrograph and is installed on all ports of the instrument. Slits are ordered separately, and should be the same size for all ports.

Order two slits for the 77250 Manually Operated Monochromator and Cornerstone 130 Monochromator. Order two slits for a Cornerstone 260 Monochromator with a single output port, and order three slits for a Cornerstone 260 with dual output ports.

Note that slits may be interchanged without affecting the instrument's calibration. However, the Fixed Slit Holder should never be removed from the monochromator.


77218固定缝有0.12毫米的宽度和18毫米的高度，如果只需要几个狭缝尺寸，这是最经济的选择。它们还提供了最大的准确性和可重复性。这种精密的狭缝固定在一个机加工的块上，滑入77294固定狭缝支架。所述固定狭缝固定器与孔单色仪或摄谱仪订购，并安装在仪器的所有端口上。狭缝是分开订购的，所有端口的尺寸应该相同。为77250手动操作单色仪和基石130单色仪订购两个狭缝。为一个单输出端口的基石260单色仪订购两个狭缝，为一个双输出端口的基石260订购三个狭缝。请注意，在不影响仪器校准的情况下，缝隙可以互换。然而，不应该从单色器中移除固定狭缝支架。
