Bi-Convex Lenses
Bi-convex lens with positive focal length is a biconvex lens lens with an incident and an emergent surface, characterized by a longer focal length at the middle of the lens surface and a shorter focal length at the end of the lens surface. It is best suited for situations where the object and image are located on opposite sides of the lens and the ratio of the image to the object distance (conjugate ratio) is between 0.2 and 5.
Biconvex lenses are primarily used to converge light from point sources or to transmit images to other optical systems. They are also commonly used in the manufacture of optical instruments such as telescopes and microscopes.
CLZ Optical Co., Ltd. stocks Bi-Convex Lenses ranging from 10mm to 250mm in diameter with a full range of focal lengths to meet your needs. We can also customize optical components to meet your requirements using a variety of optical materials, such as optical glass, fused silica, silicon.

We can modifying diameter of lenses and blacking edge in stock optics to meet your requriments.
This can achieve:
The stock optics diameter from large to small and tighter diameter tolerance.
Coated Area is a continuous coating extending to the edges of the optical component. (Edge after coating)
Edge-blackened lenses, or inked lenses, minimize the stray light within an optical system.
