Experimental CCD Spectrometer for Spectral Physics Instruments

The Experimental CCD Spectrometer for Spectral Physics Instrument is a versatile instrument designed for precise spectral measurement and analysis. Utilizing a high-performance linear CCD detector, the system enables real-time acquisition of spectral data with advanced visualization capabilities, including three-dimensional spectral displays. The instrument is suitable for studying emission and absorption spectra from a wide variety of light sources and materials. It also serves as an effective platform for wavelength calibration and optical probe verification, making it valuable for laboratory teaching, scientific research, and spectroscopy training. The optical system employs a precision grating monochromator configuration in which incoming light passes through an entrance slit, is collimated, dispersed by a diffraction grating, and projected onto a linear CCD array. This arrangement provides accurate wavelength measurement, excellent spectral resolution, and reliable repeatability. Physics Lab Experiments from Atico Exports.
