Pinhole camera picture

A magnifying glass

M = θ/θo = (h/f)/(h/N) = N/f

Compound Microscope

Object is placed just beyond focal point to create large real image. mobjective = -di/do ≈ -di/fobjective The real image from the objective lens is the object for the eyepiece lens. The image formed by the objective lens is at the focal point of the eyepiece. Meyepiece = N/feyepiece Mtotal = mobjectiveMeyepiece

Refracting telescope

α = -h/fobjective β = h/feyepiece Mtotal = β/α = fobjective/feyepiece L = fobjective + feyepiece

Terrestrial Telescope
