摘要 |
An optical apparatus is disclosed by which, even if heat is generated in optical elements in a diffraction grating-optical modulati on apparatus, lights emitted from the optical elements is less likely to suffer from displacement therebetween. The optical apparatus includes an optical element (11), a mounting substrate (50), a support member (60), and a cooling/heat radiating member (70). The support member (60) is attached to a first face (50A) of the mounting substrate (50) while the optical element (11) is attached to a second face (50B) of the mounting substrate (50). The cooling/heat radiating member (70) is attached to the support member (60). The optical element (11) and the support member (60) are thermally connected to each other by a heat transmission element (51) provided in the inside of the mounting substrate (50). The support member (60) is made of a material having a thermal conductivity of 230 W/m.K or more. <IMAGE> |
