Abstract:
An optical device (1) includes a first transparent substrate (10), a thermochromic device (20) covering a surface (11) of the first transparent substrate (10), a second transparent substrate (50), an electrochromic device (40) covering a surface (51) of the second transparent substrate (50) and a thermally insulating volume (30) separating the first transparent substrate (10) and the second transparent substrate (50). The thermally insulating volume (30) is preferably a vacuum volume or a volume (31) filled with gas.
