The measurements of oscillator strengths of the principal series of calcium are presented. The data were taken using the magneto-optical rotation (MOR) spectroscopy technique, utilizing the plane-polarized light emitted by the 2.5 GeV electron accelerator, a 6 T superconducting magnet and a 3 m long high-dispersion spectrograph. The MOR spectra were recorded on photographic plates, which were then digitized using a high-resolution densitometer tracer. More accurate oscillator strengths of transitions, 3p⁶4s^2 1S₀ ® 3p⁶4s np ¹P₁ (n = 11 to 25) have been determined.
