The peptide has the function of promoting self-renewal of human embryonic stem cells.

Abstract: Provided are an augmented reality optical module, including a first lens, a second lens, a third lens group, a first polarization modulation unit provided on a side of the third lens group and configured to modulate the light emitted by the image source into first circularly polarized light, an angle selection film provided on a first surface of one side of the first lens and configured to reflect light having an incidence angle greater than or equal to a first angle and transmit light having an incidence angle smaller than or equal to a second angle, and a second polarization modulation unit provided on the other side of the first lens and configured to modulate incident circularly polarized light into linearly polarized light.

Abstract: An augmented reality optical module includes a relay lens group and a reflection lens group. The relay lens group receives and converges the light emitted by the image source. The reflection lens group comprises a first lens and a second lens. The light emitted by the image source is incident to the relay lens group and converged to form the relay image at least once, the light of the last relay image is incident to a first surface of the first lens and reflected, the reflected light is incident to a first surface of the second lens and reflected, and then incident to the first lens and transmitted through the first lens to form imaging light. The ambient light is transmitted in such a manner that the ambient light is transmitted through the second lens and the first lens, sequentially, and then emitted to be superimposed on the imaging light.
