The model 77421 Grating Assembly is designed for installation into the Oriel MS125 Spectrograph. This 30 x 30 mm grating comes pre-aligned in its own frame, allowing it precisely fit inside the instrument. The frame has a tab that allows the grating to be inserted or replaced inside the spectrograph without touching its surface. Each grating comes with a protective cover and is labeled with the model number, making interchangeability and storage simple. The grating efficiency exceeds 20% over its entire operating range, with a peak efficiency exceeding 50% at its blaze wavelength.


77421型光栅组件是为安装到Oriel MS125光谱仪而设计的。这个30×30毫米的光栅在它自己的框架内预先对准,使它精确地适合仪器内部。该框架有一个标签,允许光栅插入或更换在光谱仪内,而不接触其表面。每个光栅都有一个保护罩,上面标有型号,便于更换和存储。光栅的效率在整个工作范围内超过20%,在其火焰波长处的峰值效率超过50%。
