Abstract
We propose a new test of the Einstein’s formula for the gravitational light deflection using the Galactic microlensing. In this classical formula, the deflection angle ∆ϕ is inversely proportional to the impact parameter p of incoming photons travelling from infinity.
Key words
Gravitational deflection of light, Einstein formula, gravitational microlensing, light curves
