An optomechanical assembly (10) is disclosed for enhancing the thermal dissipation performance of an optical system within an enclosure (12). The optical module (11) of the optical system includes a heat sink surface (20) which connects the optical module (11) to the enclosure (12). A cooling device (25) is placed between the heat sink (20) and the enclosure (12) to create high heat potential hence better dissipation. The enclosure (12) is provided with cooling elements (23) and venting holes (22) to promote better heat removal via natural convection.
