The model 77744 grating is for use with the Oriel MS257™ monochromator and imaging spectrograph. This grating is installed by Newport onto either the 77706 Single Grating Mount or 77708 Multiple Grating Mount, that can hold up to four gratings (ordered separately). The grating efficiency exceeds 20% over its entire operating range, with a peak efficiency of 75% at its blaze wavelength.

This grating may be installed into a new instrument or added to an existing instrument. Existing instruments must be sent to Newport for grating installation and calibration. During recalibration, the instrument is thoroughly assessed to ensure optimal performance and routine maintenance services are performed. The monochromator or spectrograph is returned with a Certificate of Calibration, guaranteeing the instrument meets or exceeds it specifications. Contact a Newport technical sales engineer for more information.

77744型光栅是使用凸肚MS257™单色仪和成像光谱仪。这个光栅是由新港安装到77706单光栅或77708多光栅，可以容纳四个光栅(分别订购)。光栅效率在整个工作范围内超过20%，在其火焰波长处峰值效率为75%。

这种光栅可以安装在新仪器上，也可以加到现有仪器上。现有仪器必须送到新港进行光栅安装和校准。在重新校准期间，对仪器进行彻底的评估，以确保最佳的性能和日常维护服务。单色仪或摄谱仪返回时须出示校准证书，以确保仪器符合或超过其规格。更多信息请联系新港技术销售工程师。
