Detailed Explanations of the Calculator’s Working
The thin lens calculator employs a fundamental equation in optics to derive the focal length based on the lens material’s refractive index and the radii of curvature. By inputting these values, the calculator swiftly provides the result, saving time and effort. Such calculators are often embedded in software used by optical engineers, facilitating complex design processes and ensuring accuracy.
Formula with Variables Description
1/f = (n – 1) * (1/R1 – 1/R2)
Where:
- f is the focal length of the lens.
- n is the refractive index of the lens material.
- R1 is the radius of curvature of the first lens surface.
- R2 is the radius of curvature of the second lens surface.
Example
For a lens with a refractive index of 1.5, and radii of curvature R1 = 10 cm and R2 = -10 cm, the focal length can be calculated using the formula mentioned:
1/f = (1.5 – 1) * (1/10 – 1/(-10)) 1/f = 0.5 * (0.1 + 0.1) 1/f = 0.1 f = 10 cm
The result is a focal length of 10 cm, highlighting the calculator’s utility.
