Holmarc introduces yet another product ‘Hydrogen Spectra-Balmer Series Appartus’ for the benefit of students in spectroscopy. It is specially designed for the determination of wavelengths of Balmer series from hydrogen emission spectra and to find the Rydberg constant. This apparatus comprises of high performance CCD Spectrometer, Mercury lamp with power supply and Hydrogen Spectrum Discharge Tube coupled with a High Voltage Transformer. Spectrometer utilizes grating element for spectral dispersion and is compatible with USB 2.0 interface. Better sensitivity of the CCD makes this spectrometer suitable for applications with lower light signals as well. The software developed for this instrument has facilities for capturing single or continuous spectra, custom wavelength calibration, dark subtraction and intensity comparison, simultaneous display of overlay multiple spectra, exporting data to Microsoft excel, automatically timed spectrum saving etc.
Mercury lamp is used as the standard element to find the unknown wavelengths of hydrogen. Later using the hydrogen spectrum and the energy level quantum number; Rydberg constant can be determined. High Voltage Transformer is supplied with Hydrogen Spectrum Discharge Tube. The discharging action is controlled by a variable knob and can be adjusted to get optimum performance of Hydrogen.
