Compute the radiative flux transferred from a 2.5 m2 polished aluminum plate at 1000 K to a camera that has a 2 inches optical aperture (objective diameter) and a silicon CMOS focal plane array (about 1 cm2), located 10 m away from the plate. Assume that the plate is a Lambertian radiator and all light entering the camera aperture reaches the detector array. Use Figure 1 as a guide for your calculations. Assume that the lens is completely transparent at all wavelengths, the sensor filter is a bandpass filter that completely blocks all small wavelengths up to UV and long wavelengths beyond 1 THz. In the passing band the filter is perfectly transparent. The emissivity of polished aluminum and transmittance of the atmosphere can be considered constant over the entire spectrum (search for the approximate values online –
