Thin Lens Equation Calculator

How to use the Thin Lens Equation Calculator

1. Fill in the values you know. Fields already contain typical example values that you can overwrite.
2. Pick the unit for each measurement with the selector beside the field; changing a unit converts the number for you.
3. Leave blank the value you want to find, or simply read the results panel, which updates as soon as there is enough information.
4. A value the calculator worked out is shaded in its field. Type over it to switch which quantity is calculated.

If a value is missing or does not make sense, the field shows a short message explaining what to fix.

Formulas used

This calculator is built on the following relationships between its quantities. Each one can be solved for any of the values it contains, which is why you can leave any single field empty and have it calculated from the others:

1/focal_length = 1/object_distance + 1/image_distance

magnification = abs(image_distance)/object_distance

Interpreting your results

After performing the calculation, the output provides valuable information about the image formed by the lens.

• Image Distance (d_i): The distance from the lens to the image. A positive d_i indicates a real image formed on the opposite side of the object; a negative d_i indicates a virtual image on the same side as the object.
• Magnification (M): This indicates how much larger or smaller the image is compared to the object. A magnification greater than 1 means the image is larger, while less than 1 means the image is smaller.

Common Mistakes: Be cautious of the sign conventions for focal length and object distance. Ensure the correct values are used; improper signs can lead to incorrect interpretations. Always double-check the focal length, especially if using concave lenses, which usually have negative values.
