SUMMARY

YTR-6308 multi-functional grating spectrometer is a grating as a spectrometer of spectral components, its basic principle is that when light beams of different wavelengths are incident on the grating at the same angle of incidence, different wavelengths of light beams at the same level of diffraction of the main position is different, so as to achieve the purpose of spectroscopy. Its advantage is a wide spectral measurement range and high resolution, comprehensive performance is outstanding, is currently the most widely used spectral instruments. The grating spectrometer is designed for physics experimental teaching open structure design, students can intuitively view the internal optical path and structure of the spectrometer. At the same time, the photomultiplier tube and linear CCD as a photoelectric sensor, both high-resolution spectra can be obtained, but also can quickly obtain a wide spectrum. It enables students to more fully understand and master the working principle of the spectrometer. The instrument can be well used in experiments such as hydrogen-deuterium spectroscopy experiments, sodium atomic spectroscopy, etc.

FEATURES

• Symmetrical C-T optical path structure with visual structural design to help students understand and master the structural composition and working principle of the spectrometer.

• Dual optical path design, using high quality photomultiplier tube and linear CCD as photoelectric detector respectively, which makes students understand and master the performance,advantages, disadvantages ,usage of the detector.

• Professional spectral analysis experiment software, including: spectral measurement, transmittance measurement, reflectance measurement, absorbance measurement and chromaticity measurement and other experimental modules (some experimental modules need to be equipped with additional accessories).
