Diamond transmission spectrum
WebAug 12, 2024 · To construct the transmission spectrum, we split the white light curves into 20 spectrophotometric bands, each spanning 20 nm, and compute the mean values of (Rp/Rs)^2 in each band. We compare the transmission spectrum to two sets of atmospheric models. WebAug 3, 2015 · Since diamond is optically isotropic, the same spectrum can be recorded in any direction through the sample. The faceted stone can be positioned in any orientation as long as the light transmitted through it is …
