Product description

1.What is Bi-convex Lens?  

Double Convex Lenses are used in image relay applications, or for imaging objects at close conjugates. Double Convex Lenses have 

positive focal lengths, along with two convex surfaces with equal radii. Aberrations will increase as the conjugate ratios increase. 

DCV Lenses are used in a range of industries or applications.

2.What is the difference between convex lens and double convex lens?

One or both of the lens faces is part of a sphere and can be concave or convex. A lens is called a convex lens if it is thicker at the center 

than at the edges. ... Double convex lenses have focal points on both sides of the lens; these and the points at twice the focal length are 

used to locate objects and images.

3.What does a double convex lens do?

The fact that a double convex lens is thicker across its middle is an indicator that it will converge rays of light that travel parallel to its 

principal axis. A double convex lens is a converging lens. A double concave lens is also symmetrical across both its horizontal and 

vertical axis.
