Abstract
The present disclosure provides an optical module and a head-mounted display. The optical module includes a third lens, a polarization reflecting film, a second lens, and a first lens arranged sequentially; a first quarter-wave plate is arranged between the third lens and the first lens; a beam-splitter provided a side of the first lens distal to the second lens; each of the first lens and the second lens has a refractive index less than that of the third lens; the first lens has a dispersion coefficient greater than that of the second lens, and the second lens has a dispersion coefficient greater than that of the third lens.
