Embodiment 1

[0046] Please also refer to figure 1 and figure 2 , an optical lens assembly 1 comprising at least two optical lenses. The optical lens is in the shape of a truncated cone, and each optical lens includes a first surface, a second surface and a conical surface, and the area of ​​the first surface is smaller than that of the second surface. The first surface and the second surface are light-transmitting surfaces, and the conical surface is a reflecting surface.

[0047] The size of each optical lens is different, and the optical lenses are coaxially arranged according to the size. The adjacent optical lenses include a front optical lens and a rear optical lens, and the second surface of the front optical lens is opposite to the first surface of the rear optical lens. The first surface of the front optical lens is larger than the first surface of the rear optical lens and not larger than the second surface of the rear optical lens.

[0048] As mentioned above, at least two o...

Embodiment 2

[0069] Please also refer to image 3 and Figure 4 The difference between this embodiment and Embodiment 1 is that the optical lens assembly 1 includes a first optical lens 11 , a second optical lens 12 and a conical lens 14 , and each lens is made of a transparent material such as glass or optical plastic. The conical surfaces of the first optical lens 11 , the second optical lens 12 and the conical lens 14 are all coated with a total reflection film of the wavelength of the applied light. The first and second surfaces of the first optical lens 11 and the second optical lens 12 , that is, the respective planes, are coated with anti-reflection coatings.

[0070] Coating a thin film with a higher refractive index than the base material on the optical surface is a total reflection film, which can increase the reflectivity of the optical surface. The anti-reflection coating is the opposite of the total reflection coating. A thin film with a lower refractive index than the base ...

Abstract

The present invention provides an optical lens assembly. The assembly comprises optical lenses which are in the shape of a circular terrace, each optical lens includes a first surface, a second surface and a circular conical surface, and the area of the first surface is smaller than the area of the second surface; the first surface and the second surface are illuminating surfaces, and the circular conical surface is a reflection surface; there are at least two optical lenses, and optical lenses are coaxially arranged; the adjacent optical lenses are divided into a front optical lens and a back optical lens, and the second surface of the front optical lens is opposite to the first surface of the back optical lens; and the first surface of the front optical lens is larger than the first surface of the back optical lens, ad is not larger than the second surface of the back optical lens. The optical lens assembly is an optical lens assembly capable of generating multi-dimensional and multi-layered annular cursors through adoption of a single-point light source.

Description

technical field [0001] The invention relates to the field of optical devices, in particular to an optical lens assembly. Background technique [0002] At present, the relatively simple method to obtain a ring-shaped spot with uniform energy is to use a point laser spot with good parallelism and concentrated energy to hit the reflective cone made of alloy or glass, and use the mirror reflection of the reflective cone to obtain a ring-shaped spot. Because the energy of the obtained ring-shaped spot is uniform, the line is straight, and the width is thin and consistent, it is widely used in construction, decoration, packaging and other industries that require marking. However, multi-dimensional and multi-level laser marking is currently required, and a single ring laser marking can no longer meet the demand. Contents of the invention [0003] In view of this, the object of the present invention is to overcome the deficiencies in the prior art and provide an optical lens asse...
