Conical Lens

The upper surface of a conical lens is usually a slanted cone, while the lower surface is a flat surface. This special design allows the direction of the light to change as it passes through the cone, thus forming a specific beam shape.

The conical lens is machined by computer digital control precision, with very high accuracy. At the same time, the grinding and polishing process makes the surface roughness of the conical lens well controlled, and the RMS value of the surface roughness is usually very small.

Conical lenses can be divided into transmission conical lenses and reflection conical lenses according to the different mode of light action. In addition, according to the specific application scenarios and needs, conical lenses can be further subdivided into different types of conical lenses, such as conical lenses, corner conical prisms, etc.

When a beam of parallel light is shot into the transmission conical lens, the direction of the light will change on the conical surface, and then form a ring beam. This circular beam has the characteristics of a Bezier beam, so it is often called a "Bezier ring".

The reflective conical lens can produce a unique beam shaping effect. When a parallel beam of light shines on the surface of a reflecting conical lens, it produces a ring beam with the same width. By adjusting the distance between the two conical lenses, the radius of the outgoing ring beam can be easily changed.

Annular light sources can provide a more uniform lighting effect than point light sources. Therefore, conical lenses are often used in optical systems that require uniform illumination, such as projectors, microscopes, etc.

Conical lenses are also widely used in the field of laser processing. By adjusting the parameters of the conical lens, the shape and size of the laser beam can be controlled, so as to achieve accurate cutting and drilling of the processed material.

In the field of medical cosmetology, conical lenses are also used to produce beams of light with specific shapes to meet the needs of different cosmetic treatments. For example, the circular beam generated by the conical lens can be used for skin tightening, wrinkle removal and other cosmetic treatments.

The manufacturing process of conical lens usually includes material selection, blank production, precision machining, polishing and coating. In the manufacturing process, the process parameters and quality standards of each link need to be strictly controlled to ensure that the performance and quality of the final product meet the design requirements.

To sum up, the conical lens, as a special optical element, plays an important role in the optical system. Its unique shape and optical properties make conical mirrors widely used in many fields such as uniform lighting, laser processing and medical cosmetology.
