Abstract
An optical system for collimation of incoming light, comprising: a body (); a recess () formed on a first side () of the body (), the recess () having a central light entry surface () and a side light entry surface (); a central light exit surface () provided at a second side of the body (), which second side () is opposite to said first side (); said central light entry surface () being arranged in relation to the central light exit surface () such that incoming light falling on the central light entry surface () is directed to the central light exit surface (), a total internal reflection surface () provided at a side surface of the body (), which is arranged such that incoming light falling on the side light entry surface () of the recess () is directed towards the total internal reflection surface () so as to be subject to total internal reflection towards the second side () of the body (); and a rejection area () surrounding said central light entry surface (), said rejection area () being configured to prevent incoming light to exit said body () through said second side ().
