Product Description

What is a double convex lens?
Bi-Convex (Double-Convex) lenses have the same radius of curvature on both sides of the lens and function similarly to plano-convex lenses by focusing parallel rays of light to a single point. ... Bi-Convex lenses are the best choice when the object and image are at equal or near equal distance from the lens.
 

How double convex lens work?
A double convex lens, or converging lens, focuses the diverging, or blurred, light rays from a distant object by refracting (bending) the rays twice. ... This double bending causes the rays to converge at a focal point behind the lens so that a sharper image can be seen or photographed.

Technical Information

 

 

 

 What is the magnification formula for lenses?
   Magnification formula for lenses. Let's explore the magnification formula (M= v/u) for lenses and see how to find the image height and its nature (whether it's real or virtual). Created by Mahesh Shenoy.

What is application of double 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. ... 

Processing

Testing

 

Oplens equipped Zygos which work by producing a beam of laser light and transmitting it to the optic under test by way of a very, very accurate lens fitted to the Zygo. This is the key to the instrument's accuracy. As the light passes through this lens, which is not coated, it enables 4% of the light to be reflected back into the Zygo.
