Visit us at BOOTH 2549 at SPIE PHOTONICS WEST from 30 January to 1 February 2024 at Moscone Center in San Francisco, California, USA
The Oplens team would like to extend our heartfelt thanks for your cooperation. We hope that this holiday season brings you joy, peace, and prosperity. Happy winter solstice!
Measuring the surfaces of thin, parallel optics can be challenging. When optics are less than a few millimeters thick, their front and back surfaces are so close together that it is difficult for standard interferometry to tell them apart.
Spherical lenses - also sometimes referred to as singlets - are optical lenses that feature a spherical surface with a radius of curvature that is consistent across the entire lens.
Spherical lens refers to a type of optical lens with one or two surface shaped like a cut of sphere, meaning this surface can be defined from a center reference point and a fix radius of curvature. Spherical lens are the more commons form of optical lens, being easier to design, easier to manufacture and easier to check the quality. In this articl
Explaining the Difference Between Anamorphic and Spherical Lenses
A double concave lens, also known as a biconcave lens, is a type of lens that has two concave (curving inward) surfaces. This means that the lens is thinner in the center and thicker at the edges, creating a negative lens that diverges light rays.
Optical Component Production Process
Anti-reflection coatings are used to reduce reflection from surfaces. Whenever a ray of light moves from one medium to another
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.
