Double convex lens

A biconvex lens is suitable for situations where one conjugate distance is 0.2 to 5 times the other conjugate distance. The performance of this lens shape is suitable for situations where the object distance and image distance are the same.

There is also an external lens in the biconvex lens, which has a smaller spherical aberration.

Appearance lens:

The external lens design is used to minimize spherical aberration and coma (aberrations introduced by light that is not on the optical axis), while still utilizing the spherical surface to form the lens. Using spherical design makes the outer lens easier to manufacture than non spherical lenses, reducing costs. Each side of the external lens is polished to have different curvature radii, providing better performance for spherical single lenses. For small diameter input beams, the external lens even has diffraction performance. These lenses are typically used in high-power applications where achromatic adhesive lenses cannot be used. The design of the external lens is to minimize aberrations while still utilizing a spherical surface to form the lens. These lenses are optimized for infinite conjugate ratios and are highly suitable for focusing collimated beams or collimating point light sources.

A biconvex lens, also known as a double convex lens, is a common optical component that has outward convex surfaces on both sides. The two sides of this lens can be spherical or non spherical, but the most common shape is that both sides are spherical. A biconvex lens is a type of converging lens that can focus light passing through it.

application area

Double convex lenses have applications in many fields due to their ability to converge light rays

  • optical instrument:Such as magnifying glasses, microscopes, telescopes, etc., used to focus light to enlarge images.
  • Photography and Video:Used in camera lenses for focusing and adjusting images.
  • laser technology:Used to focus laser beams and improve the efficiency of laser action.
  • lighting:In flashlights or stage lighting, used to focus or disperse light to achieve the desired illumination effect.

advantage

  • Simple and efficient:The double convex lens has a simple structure, stable optical performance, and is easy to manufacture and use.
  • WIDELY:Suitable for various optical systems, the biconvex lens can be selected with different materials and parameters according to needs.
  • Good focusing ability:It can effectively focus light and improve the imaging quality and efficiency of optical systems.

note

Although biconvex lenses have many advantages, their limitations should also be noted during use, such as the occurrence of optical distortions such as spherical aberration and chromatic aberration. To improve imaging quality, it is usually necessary to reduce these distortions through lens combinations or the use of special designs such as non spherical lenses.

Overall, biconvex lenses are fundamental and important components in optical design and applications. Through proper design and use, efficient light control and composition can be achieved in various optical systems
