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 890 nm and with a mode line separation of 0.8 nm. The comb lines will be scanned over a full mode spacing (0.8nm) being this characteristic 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 not only calibrate the wavelength response of this unit but also its line-spread-function.

积分场分光光度计PMAS的波长校准测试使用innofSPEC-AIP开发的创新光频梳光源。该光源包括一组等距的光谱线，覆盖从725至890 nm的光谱范围，并且模式线间隔为0.8 nm。梳状线将在全模式间隔（0.8nm）上被扫描，这是世界上使用这种类型的仪器所独有的特性。通过在PMAS光谱仪中输入梳状光，并将每条线与光谱仪检测器中的像素相关联，我们不仅可以校准该单元的波长响应，还可以校准其线扩展函数。
