摘要： An optical scanning device (1) for scanning an information layer (4) of an optical record carrier (2), the device (1) comprising a radiation source (11) for generating a radiation beam (12, 15, 20) and an objective system (18) for converging the radiation beam on the information layer, the information layer being covered by a transparent layer (3) of thickness td and refractive index nd. The objective system comprises a lens having a protection device projecting away from the lens towards the optical record carrier such that the distance between the protection device and the optical record carrier is less than the free working distance. The lens satisfies the condition: where D is the entrance pupil diameter, FWD is the free working distance, and D, FWD, t and td are all expressed in millimeters and where FWD + td/nd

摘要： An optical element for reflecting solar light has excellent weather resistance, and furthermore, a high reflectance in a wide band. When solar light enters an optical element (OE), light (L1) in a short wavelength band among the solar light is reflected by a dielectric multilayer film (DF). Other light (L2) in longer wavelength bands are passed through the dielectric multilayer film (DF), then a base material (SS), and reflected by a metal deposition film (MV) to pass through the base material (SS) and the dielectric multilayer film (DF). Thus, high reflectance in a wide band is ensured.
