Let us consider five different situations for a converging lens (f > 0). You can check it with our thin lens equation calculator!

We encourage you to check similar cases for the diverging lens, which has a negative focal length f < 0 with our calculator!

The magnification of a lens is the ratio of the size of the image to the size of the object. Hence, to find the magnification of a lens, take the ratio of the two. You can also calculate magnification by taking the ratio of the image-lens distance to the object-lens distance.

The thin lens equation calculator will help you to analyze the optical properties of the simple lens. Keep reading to learn about the thin lens equation and understand how a lens can magnify the image of an object. Everything is about light, so be sure to check out the principles of light refraction too!

Remember that magnification must always be a positive number. That's why we have taken the absolute value of y, which generally may be both positive and negative.

There are two basic types of lenses. We can distinguish converging lenses, which have focal length f > 0, and diverging lenses for which focal length f < 0. It should also be noted that when the image distance is positive y > 0, then the image appears on the other side of the lens, and we call it a real image. On the other hand, when y < 0, then the image appears on the same side of the lens as the object, and we call it a virtual image.

The power (P) of a lens is the reciprocal of its focal length (f). Hence we can express the formula for the power of a lens as:

You can compute the magnification of the created image, too (see the mirror equation calculator). It can be easily estimated if we know the distance of object x and the distance of image y:

Ideal for extending short cables if you need to use a pc sometimes close to a socket and somtimes further away, if wifi is bad, without having metres of cable piled up on the floor half the time.

-The compact size of this coupler allows for the extension of network cables in tight spaces, such as behind TVs or desks;

-Support PoE applications, providing enhanced versatility for your networking setup, especially for IP cameras and VoIP.

No, the thin lens formula is not different for different lenses. The thin lens formula is the same for both convex and concave lenses.

Experience lightning-fast network speeds of up to 10 Gbps and a bandwidth of 600 MHz, meeting the stringent standards of Category 7 performance as per the ASNI/TIA/EIA 568C standard.

If we place the object near the lens, we will get its image somewhere. The position, orientation, and size of this image depend on two things: the focal length of the lens (which is specific for the particular lens) and the position of the original object. We can predict what we will see with the following thin lens equation:
