WitrynaThe WFC3 (F140W, F125W, and F336W) and archival WFPC2 (F702W and F450W) imaging provides five-filter photometry that we use to detect 3375 sources between z ≈ 0-6, including 1536 objects in a deep central pointing with both spectroscopic and photometric coverage. Witryna10 lut 2024 · Raman Imaging. In contrast to Raman mapping, Raman imaging is like taking a photo; Spectral intensity values are collected simultaneously from the whole region of interest. The laser illuminates a square or circular region on the sample. Light is filtered, to record the intensity of just one narrow part of the spectrum. fishers locksmith prosWitrynaBetween 780-2500 nm, substances such as plastic, organic compounds, and non-organic compounds can be easily differentiated, which is hard to do in the visible range.
