Optical Windows Available from Astar photonics inc.Our state of the art factory is able to manufacture both large optical windows. A wide variety of optical substrates are available to choose from, and since production is carried on in-house our design team […]
This is the type of lens that has a curve in such a way that it is thin on the edges, but when it comes to the center, the lens is rather thick. In other words, if the surface of a lens is seen to be curved outside, then it is identified as a biconvex […]
Founded in 2011, A-Star Photonics Inc is a manufacturer of lenses in China. In technology research and development and product promotion, always stand in the forefront of the industry, to provide consumers with a full range of visual solutions.

Or focusing applications utilizing monochromatic illumination, in a range of industries including industrial, pharmaceutical, robotics, or defense. Plano-convex Lenses have one convex surface. For maximum efficiency, the second, Plano (flat) surface should face the desired focal plane. Plano-Convex lenses are commonly used in a wide range of applications or industries. Astar photonics are points are […]
Plano-Convex lenses are the best choice for focusing parallel rays of light to a single point. They can be used to focus, collect and climate light. The asymmetry of these lenses minimizes spherical aberration in situations where the object and image are located at unequal distances from the lens. N-BK7 lenses are a great choice […]
Plano-concave lenses are useful for a wide range of applications. These lenses are manufactured from BK7A grade A (or customer design) optical glass and are supplied uncoated. Anti-reflection coatings are available as listed earlier in this section. To order an anti-reflection coated lens, simply append the wavelength in nanometers to the product number. A-STAR photonics […]
