The 77250-MC is a fully assembled, pre-aligned, Hand Operated Monochromator. The monochromator is based on an Ebert-Fastie design, placing the grating out of the path of the entrance and exit slits, to eliminate re-entrant spectra. The hand operated design allows for output wavelength adjustment as accurate as 1 nm. A three digit counter display displays the output wavelength with resolution as great as 0.1 nm. The micrometer adjustable slit assemblies are ideal for general laboratory or academic use, in which a versatile, conveniently adjustable slit height and width are desirable. These slit assemblies also provide a larger dimensional adjustment range and higher throughput than the fixed slit version of this monochromator, the 77250-FH. The micrometer driven slit assemblies have an adjustable slit width from fully closed to 3 mm (4 µm minimum achievable open width) and a slit height adjustable from 2 to 12 mm. Oriel offers a variety of gratings, sold seperately. These gratings are interchangeable, depending on the needs of the application, and cover a wavelength range from 200 nm to 23 µm. The 77387 mounting kit (sold seperately) allows the monochromator to be mounted in a setup with an easily adjustable optical axis height to match that of a source and/or detector.


77250-MC是一个完全组装，预对准，手动操作单色器。单色器基于Ebert-Fastie设计，将光栅放置在入口和出口缝隙的路径之外，以消除可重入光谱。手工操作的设计允许输出波长调整精确到1纳米。三位数计数器显示输出波长，分辨率高达0.1 nm。微米可调缝组件是理想的通用实验室或学术用途，其中一个通用，方便可调缝高度和宽度是可取的。这些狭缝组件还提供了更大的尺寸调整范围和更高的吞吐量比固定狭缝版本的单色器，77250-FH。测微驱动缝组件有一个可调的狭缝宽度从完全关闭3毫米(4µm最低可实现的开放宽度)和狭缝高度可调从2到12毫米。Oriel提供各种光栅，分别出售。这些光栅是可互换的,根据应用程序的需要,涵盖了从200 nm波长范围到23µm。77387安装套件(分别出售)允许单色器安装在一个设置与一个光源和/或探测器的光轴高度容易调整的设置。
