Multifunctional Grating Spectrometer Monochromator for Spectral Physics Instruments

The Multifunctional Grating Spectrometer Monochromator for Spectral Physics Instruments is a versatile optical instrument designed for the study of spectroscopy, optical measurements, and wave phenomena. Its modular architecture allows users to adapt the instrument to a variety of experimental requirements by selecting different gratings, detectors, and accessories. The system supports both photomultiplier tube (PMT) and CCD detection modes, enabling either highly sensitive signal detection or real-time spectral acquisition. A mechanical switching system allows convenient selection between operating modes. When the CCD detector is removed, the instrument can also function as a precision monochromator for accurate wavelength selection and measurement. Light entering the spectrometer is dispersed by a diffraction grating into its component wavelengths. The selected detector captures the resulting spectrum for analysis, allowing users to perform qualitative and quantitative optical investigations. Optional accessories further expand the system’s capabilities for absorbance measurements and fiber optic applications. Physics Lab Experiments from Atico Exports.
