Compensating lens set and virtual reality apparatus with the same
Disclosed are a compensating lens set and a virtual reality apparatus with the same. The compensating lens set is applied to a folded optical path system. The folded optical path system sequentially comprises, in an optical axis direction, a display unit, a first lens set and a diaphragm. The compensating lens set is arranged between the first lens set and the display unit, the compensating lens set comprising a first compensating lens, the first compensating lens comprising a first surface and a second surface. The first lens set comprises a third surface and a fourth surface. An incident light emitted by the display unit enters the first compensating lens from the first surface, and is emitted out of the first compensating lens from the second surface, passes through the first lens set, and then is transmitted to the diaphragm.
1. A compensating lens set for application to a folded optical path system, the folded optical path system sequentially comprising, in an optical axis direction, a display unit adapted to emit incident light and a first lens set and a diaphragm;
wherein the compensating lens set is arranged between the first lens set and the display unit, the compensating lens set comprising a first compensating lens having a first surface proximate to the display unit and a second surface distal from the display unit, and configured to eliminate spherical aberration of the folded optical path system, wherein the first surface and the second surface are each aspherical structures;
the first lens set further having a third surface proximate to the display unit and a fourth surface distal from the display unit; such that the incident light emitted by the display unit is reflected by the third surface and the fourth surface;
wherein the incident light enters the first compensating lens from the first surface, is emitted out of the first compensating lens from the second surface, passes through the first lens set, and is transmitted to the diaphragm;
wherein the compensating lens set further comprises a second compensating lens arranged between the first compensating lens and the first lens set, having a fifth surface proximate to the first compensating lens and a sixth surface distal from the first compensating lens; and
wherein the fifth surface and the sixth surface are each spherical surfaces, and a refractive power of the compensating lens set is the opposite of a refractive power of the first lens set.

3. The compensating lens set of claim 1 , wherein the fifth surface and the sixth surface are each aspherical structures.
4. The compensating lens set of claim 1 , wherein a distance from a center of the display unit to a center of the fourth surface is less than or equal to 25 mm.
5. The compensating lens set of claim 1 , wherein the compensating lens set is made of an optical plastic material.
6. A virtual reality apparatus, comprising:
a folded optical path system, and
the compensating lens set of claim 1 .
