The model 74020 Grating Assembly is designed for installation into the Oriel Cornerstone 130 family of monochromators. This 30 x 30 mm grating comes bonded to a mount, allowing it to be installed inside the instrument. The grating efficiency exceeds 20% over its entire operating range, with a peak efficiency of 60% at its blaze wavelength.

This Grating Assembly may be installed in the field, after which the grating must be aligned and calibrated. However, it is suggested to return the instrument 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 is returned with a Certificate of Calibration, guaranteeing the instrument meets or exceeds it specifications.

74020型光栅组件设计用于安装到Oriel基石130系列单色器。这个30×30毫米的光栅连接到一个安装，允许它安装在仪器内部。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为60%。

这种光栅组件可以安装在现场，之后必须对光栅进行校准和校准。但建议将仪器送回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。单色仪返回时附有校准证书，保证仪器符合或超过其规格。
