Rigorous dimension standard control;
The coating can be customized according to requirements;
According to user needs, we can provide cutting, edging, coating and complete installation services
The spherical lens processed by Hanzhong Borisun Optics has a good reputation in the industry. Our company is equipped with foreign advanced processing equipment, which can process various spherical lenses according to customer requirements
▶ The spherical biconvex lens has chromatic aberration, and the focal length changes with the wavelength. The actual focus distance corresponding to different wavelengths.
▶ The spherical aberration of a biconvex lens is larger than that of a planoconvex lens, and sometimes the focal spot cannot be concentrated at one point.
▶ Because of the reflection loss on the front and back of the uncoated lens, the transmittance is about 90%.
The biconvex lens is completely symmetrical. It is generally used to form a real image of things, with a change rate of 0.2 to 5. Beyond this range, the planoconvex lens will be more suitable. The biconvex lens can be used as a magnifying glass, objective lens and some focusing occasions.
Because both surfaces of a biconvex lens have an impact on the lens performance, it has a shorter focal length than a planoconvex lens on the premise of the same diameter and surface radius.
Lens can be added with antireflective coating. For coating, please refer to the coating section of our official website.
For example, we are producing BK7 biconvex lens with positive focal length, incident light correction, both real and virtual images, and smaller spherical phase difference, divergence, distortion and other characteristics under unit change rate.
