A holding apparatus (40) for spectrum measurement of optical elements includes a fixed board (11) having a first through hole (111), and a receiving board (12) having a plurality of receiving holes (120) with different sizes configured for holding different optical elements. The receiving board is coupled to the fixed board and rotatable relative to the fixed board about a first axis. The receiving holes are centered on a first imaginary circle which is centered on the first axis. A distance between a center of the first through hole and the axis is equal to a radius of the first imaginary circle.
