Thin Lens Equation calculator
Image distance & magnification from object distance and focal length.
Category: Geometric Optics
Formula: 1/f = 1/do + 1/di · m = -di/do
Inputs
| Input | Parameter | Unit | Default |
|---|---|---|---|
| Focal length | f | mm | 50 |
| Object dist | do | mm | 200 |
Result with the default inputs
- Image dist: 66.6667 mm
- Magnification: -0.3333×
Open it with your own values: put each input in the address as a parameter, for example /calculators/thin-lens-equation?f=50. A unit other than the listed one goes in <parameter>_unit.
