The wavelength calibration tests with the Integral Field Spectrophotometer PMAS uses an innovative optical frequency comb source developed at innoFSPEC-AIP. This source comprises a set of equally spaced spectral lines covering the spectral range from 725 to 850 nm, and with a mode line separation of 1.2 nm which is unique in the world with this type of instrumentation. By feeding the comb light in the PMAS spectrograph and associating each line with pixels in the spectrograph detector we will calibrate this unit.

积分场光谱仪PMAS的波长校准测试使用了InnoFSPEC-AIP开发的创新光学频率梳光源。这种光源包括一组等间距的谱线，覆盖的光谱范围从725到850 nm，模线间隔为1.2 nm，这在世界上使用这种类型的仪器是独一无二的。通过将梳状光送入PMAS光谱仪，并将每一条线与光谱仪探测器中的像素相关联，我们将校准这个单元。
