Embodiment 1

[0032] Such as figure 1 As shown, the present invention relates to an eyepiece, which includes a first lens part 1 and a second lens part 2, the first lens part 1 is connected to the second lens part 2, and the first lens part 1 The viewing angle and the viewing angle of the second lens portion 2 form the overall viewing angle of the eyepiece.

[0033] The first lens part 1 and the second lens part 2 are glued together by optical photosensitive glue.

[0034] The angle formed by the image side surfaces of the first lens portion 1 and the second lens portion 2 is 130°. When connecting the first lens part 1 and the second lens part 2, if the angle between the image sides of the two lens parts is chosen to be designed as an acute angle, the overall field of view of the eyepiece will be weakened, and it will also bring great manufacturing difficulties. Therefore, the The included angle on the side of the image is designed as an obtuse angle to maximize the field of view of the e...

Embodiment 2

[0046] Such as figure 1 As shown, the present invention relates to an eyepiece, which includes a first lens part 1 and a second lens part 2, the first lens part 1 is connected to the second lens part 2, and the first lens part 1 The viewing angle and the viewing angle of the second lens portion 2 form the overall viewing angle of the eyepiece.

[0047] The first lens part 1 and the second lens part 2 are injection molded together through integral molding.

[0048] The angle formed by the image side surfaces of the first lens part 1 and the second lens part 2 is 110°.

[0049] The overall field of view of the eyepiece is set to 70°.

[0050] The viewing angle of the first lens part 1 is designed to be 40°, and the viewing angle of the second lens part 2 is designed to be 30°.

[0051] The first lens part 1 is an aspheric lens.

[0052] The focal length of the first lens unit 1 is 60 mm.

[0053] The center thickness of the first lens part 1 is 20 mm, and the edge thickness i...

Abstract

The invention discloses an eyepiece and spectacles equipped with eyepieces. The eyepiece includes a first lens part (1) and a second lens part (2). The first lens part (1) is connected with a second lens part (2). An integral view field angle of the eyepiece is formed by the view field angle of the first lens part (1) and the view field angle of the second lens part (2). The spectacles equipped with the eyepieces include a frame (3). The frame (3) includes a plurality of eyepiece holding racks (4) and bridge parts (5) connected to adjacent eyepiece holding racks (4); and at least two eyepiecesarranged in the eyepiece holding racks (4). The invention solves technical problems of large lens number and narrow view field angle due to coaxial arrangement of a plurality of lens in the prior art.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to an eyepiece and glasses equipped with the eyepiece. Background technique [0002] The helmet-mounted display is a popular product in the display field in recent years, and the helmet image display device for virtual reality and augmented display has made great progress. Since the helmet display device is installed on the observer's head, it must be compact and light in weight to reduce the burden on the observer's head. The helmet-mounted display is mainly composed of three parts: the display part, the optical system and the helmet. Among them, the optical system is the core of realizing virtual reality technology. [0003] The optical system has the function of displaying miniature images in front of human eyes to form a virtual magnified image. However, there is a certain contradiction between the compactness of the optical system and the requirements of the head-mounted di...
