English
The convex lens is a convex lens. The convex lens includes an incident surface and an radiating surface. It is characterized by a longer focal length at the middle of the lens surface and a shorter focal length at the end of each lens surface. Lenticular lenses are mainly used to focus light from point sources or to transmit images to other optical systems.
ATOPTIK’s double convex lens is a common and essential optical component widely used in optical imaging, laser focusing, beam collimation, fiber coupling, and applications in medical, industrial, and scientific research. With a symmetrical structure featuring convex surfaces on both sides, this lens excels in light convergence and imaging performance.

Symmetrical Double-Convex Structure
The double convex lens has convex surfaces on both sides with a fixed focal length, effectively focusing incident light to a point and reducing beam dispersion.
Ideal for light convergence and optical imaging, especially in short- and mid-focus optical systems.
High Optical Precision
Precision manufacturing ensures low aberration and high-resolution imaging, with surface quality reaching 40/20 or higher, providing excellent smoothness and clarity.
Outstanding surface accuracy and optical performance minimize light loss and scattering in the optical path.
Various Material Options
Available in different optical materials based on application needs, including BK7 optical glass, fused silica, and sapphire.
BK7 is suitable for visible and near-infrared (VIS-NIR) applications, fused silica supports a wide spectral range from UV to NIR, and sapphire offers exceptional mechanical strength and heat resistance in harsh environments.
Coating Options and High Transmission
Custom anti-reflection (AR) coatings can be applied to the lens surface to reduce reflection losses and enhance transmission efficiency, with common coating ranges such as 400-700 nm, 1064 nm, and 1310/1550 nm.
Suitable for laser systems, optical instruments, optical communications, and other applications sensitive to light loss.
