The invention relates to glass with high transmissivity of ultraviolet A and a preparation method for the same. The constituents of the glass comprise, by mass fraction, 62-68% of SiO2, 2-4% of Al2O3, 6-12% of Na2O, 2-6% of K2O, 5-10% of alkaline-earth metal oxide, 7-11% of PbO, 0.1-3% of NiO, 0.1-1% of CoO and 0.1-0.2% of FeO3. The preparation method comprises the following steps of: by mass fraction, preparing glass batch according to the ratios; melting for 6-10 hours at 1400-1480 DEG C; and preparing the glass with high transmissivity of ultraviolet A by vertical or horizontal tube-drawing process. The glass disclosed by the invention can transmit ultraviolet A with a wavelength of 320-400 nm and stop the transmission of visible light; and compared with conventional ultraviolet-transmitting quartz glass, the glass disclosed by the invention is low in melting point, simple in preparation process and high in yield.
