Abstract

A dispersive element is disclosed which is designed to receive incident light (1) and disperse the incident light (1) into multiple spatially separated wavelengths of light. The dispersive body (DB) comprises a collimation cavity (COLL) to collimate the incident light (1), at least two optical interfaces (PRIS) to receive and disperse the collimated light (2) and a collection cavity (CLCT) to collect the dispersed light (3) from the at least two dispersive interfaces (op1, op2) and to focus the collected light (4).
