Optical lens group and near-to-eye display device

The utility model discloses an optical lens group, which comprises a PBS prism, the PBS prism comprises a light incident surface, a light collimation surface and a light emergent surface, the PBS prism further comprises a polarization selection beam splitter, and the polarization selection beam splitter is located on a plane, obliquely intersected with the light incident surface, in the PBS prism; image light enters the PBS prism from the light incidence surface; the reflecting mirror is positioned on one side of the light collimating surface and is used for reflecting and collimating the image light emitted from the light collimating surface; the image light reflected by the reflector passes through the PBS prism and then is emitted from the light emitting surface; and at least one lens located on a transmission path of the image light. According to the optical lens group provided by the utility model, by using the reflector and combining the PBS prism, the aberration of the system can be corrected, and the
