Double Convex Lens

 The 2 plano 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.

 

Overview of Double Convex Lenses


ATOPTIK’s double convex thin 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.

 

Specifications of Double Convex Lens

Features of Double Convex Lens

 

Symmetrical Double-Convex Structure

 

The a 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.

 

As an optics supplier, we will do our best to meet all the needs of customers.

Plano Convex Lens

Image
  ATOPTIK can process ultra-high precision optical plano convex lens  with ultimate surface accuracy up to λ/20 and a maximum diameter of Ø150mm.   Overview of plano convex laser lenses A plano convex spherical lenses  consists of one flat surface and one convex surface, with a positive focal length. It can focus parallel light rays into a point or transform a point light source into a collimated beam. When in use, it is generally recommended to orient the convex surface toward the incident light to minimize spherical aberration.   Applications of Plano Convex Lens 1. Optical Focusing and Collimation Plano-convex lenses are widely used in laser systems for focusing high-energy beams, such as in laser cutting and welding, or for collimating divergent light sources. Their positive focal length and ability to reduce spherical aberration make them ideal for applications where precise beam shaping and minimal distortion are essential.   In imaging devices like m...
