C、配置

9072DS双减法单色仪配置

9072DS由2个单色仪以减法模式制成：第二个单色仪的色散与第一个单色仪的色散相反。两个光栅机械连接并精确地电动在一起。这会在第二个单色仪的输出端口处产生光谱均一的光束，并大大减少了杂散光，非常适合光谱辐射法，拉曼或紫外线测量太阳辐射。

9072DS的排列使其可以用作可调带通滤波器或可调陷波滤波器。作为可调带通滤波器，设备的带通由中间缝隙的宽度决定。作为可调陷波滤波器，陷波的宽度由放置在中间狭缝位置的不透明陷波的物理宽度确定。

通过使用自定义的中间多狭缝掩模而不是单个宽度的中间狭缝，9072DS还可以用于通过或滤除几种选定的波长。请联系科学技术应用专家，以告诉我们您的自定义要求。独立软件由Sciencetech提供。

9072DA双加法单色仪配置

9072DA由2个单色仪以加和模式制成：第二个单色仪的色散与第一个单色仪的色散相加。

入站光被第一光栅散射，然后穿过中间缝隙，杂散光在此处被阻挡，然后第二光栅再次光谱分散。机械地连接并校准了两个光栅，以进行精确的波长跟踪。

与单个9072单色仪相比，9072DA的双色散可带来更好的光学分辨率，而带通仅为单个9072的一半。

D、配件

1）光栅选择

为单色仪选择光栅时，需要考虑三个基本参数。

l 所需的波长范围

可用的波长范围取决于所选的光栅凹槽密度和单色仪的角度机械限制。

l 光栅效率

可以烧出直纹光栅以增加其在特定波长带上的效率。全息光栅可以被调制，使得它们在某些波长处比在其他波长处更有效。光栅效率曲线是确定适用于您的应用的最有效光栅的工具。

重要的是要注意，光栅效率曲线并不代表在单色仪中使用光栅时所期望的确切效率，因为光栅效率曲线是在Littrow角处拍摄的。

l 所需的分辨率和带宽

分辨率是衡量仪器分离相邻光谱线的能力的指标。分辨率通常以nm为单位。带宽（或带通）是任一时间落在输出端口上的波长范围，也以nm为单位。当在单色仪的输出端口上集成线性阵列或CCD之类的摄像机时，这是一个重要的参数。

* Several additional gratings available. Please contact a Sciencetech Application Scientist to find alternative gratings to suit your application.

** <30% of a properly F matched input beam will be incident on the grating at this wavelength due to the monochromator geometry

*** At this wavelength the grating is perpendicular to the input radiation and therefore the throughput is 0.

? Each grating requires its own holder to protect it during handling.

2）狭缝组装选项

所有9072系列单色仪均标配一个可调狭缝，并且如下图所示，单独提供了更多选项。 Sciencetech可以制造定制缝。
