beskrivelse:

Optical geometry of a gravitational lens where,

\alpha

is the bending angle,

\theta _{S}

is the actual angle subtended (without lens effect) by the source at the observer,

\theta _{1}

is the observed angle subtended (due to lens effect) by the apparent source at the observer,

D_{L}

D_{S}

is the angular diameter distance to the source, and

D_{LS}

is the angular diameter distance between the lens and the source.
