Determine the optical magnification of any lens quickly and accurately with our free online calculator. Understand how lenses enlarge or reduce images by inputting your image and object distances. Perfect for students and professionals studying lens properties and image formation in optics.
Formula:
The formula for lens magnification (M) is:
M = - (di / do)
Where:- M = Magnification (dimensionless)
- di = Image Distance (distance from the lens to the image)
- do = Object Distance (distance from the lens to the object)
A negative magnification indicates an inverted image, and a positive magnification indicates an upright image. The absolute value |M| > 1 means the image is enlarged, and |M| < 1 means it's reduced.
