Bi-Convex (Double-Convex) lenses have spherical outwards shape in both surfaces. These surfaces have equal radius of curvature (ROC). Choose or request material, size, shape. Optional AR coating available.
What is Double convex (Bi-Convex) Lens?
Bi-Convex (Double-Convex) lenses have spherical outwards shape in both surfaces. These surfaces have equal radius of curvature (ROC) and work in very similar principle as spherical plano-convex lenses. Double convex lens has positive focal length and perform most efficiently at magnification from 0.2 to 5 times. To achieve minimal spherical aberration, coma and distortion, DBX(CXCX) lenses should be used at 1:1 conjugate ratio.
What is the purpose and main functions of Double Convex (Bi-Convex) Lenses?
Key functions of double convex (DCX) Alien Photonics lens are converging of light rays, image formation, magnification, focusing light on instruments. While in laser-based applications bi convex lens are primary used for laser beam focusing.
Double Convex (Bi-Convex) advantages over Plano-Convex lens
Symmetrical focusing
Bi convex lens have symmetrical surfaces which makes them particularly effective for applications requiring symmetrical beam focusing from both sides of the lens. This can be advantageous in setups where light passes through the lens in both directions or where uniform focusing characteristics are needed on both sides of the lens.
High magnification
In setups requiring high magnification, Alien Photonics bi-convex lenses can offer better performance. Their symmetric design can help maintain image quality and focus precision when used in optical systems that magnify the laser beam or image significantly.
