Aspheric and freeform lenses, whose surfaces have no symmetry around an axis of rotation. They may appear to have an irregular shape, and they offer new opportunities and challenges for designers and manufacturers.
Many optical designers have found aspheric lenses to be a favorable solution in situations where conventional spherical optics fall short.
The generation of Bessel beams with axicons is the most noted application for this uncommon type of aspherical surfaces. A more complex setup of combining several axicons and a common spherical lens will be the main aspect in the beam shaping consideration within this article.
Spherical lenses, also known as singlets, are optical lenses with curved surfaces that cause light rays to converge or diverge. They are widely used in imaging applications.
Optics production offers various technologies for the optical coating process. The choice depends on the properties of the raw material and the specifications of the optical systems/products.
Even with sophisticated lens systems, it can be difficult to get an entire image in focus. With any spherical surface, the light will bend differently depending on where on the surface the light is passing through.
On December 25, 2021, Oplens ushered in his 16th anniversary. All Oplens people gathered together to celebrate his birthday.
In the middle of September, the three-day China International Optoelectronic Exposition (CIOE) was held as scheduled.
In nature, any object with a temperature above absolute zero (-273℃) can emit electromagnetic waves. Infrared is the most widespread form of electromagnetic waves in nature, it is a kind of energy, and this energy is invisible to our naked eyes.
Oplens (brand own by SiChuan JUKA Optical Technology) is located in the city of Chengdu, China, which enjoys the reputation of the world optical processing center.
