Ultraviolet-visible spectroscopy or ultraviolet-visible spectrophotometry (UV-Vis or UV/Vis) involves the spectroscopy of photons in the UV-visible region. This means it uses light in the visible and adjacent - near ultraviolet (UV) and near infrared (NIR) - ranges. The absorption in the visible ranges directly affects the color of the chemicals involved.. Spectrophotometers Prominent & Leading Manufacturer from New Delhi, we offer spectrophotometers, microprocessor uv/double beam spectrophotometer, single/double beam microprocessor spectrophotometer and atomic absorption spectrophotometers.. A block diagram of a classic dispersive IR spectrometer is shown in Figure C. Figure C Dispersive IR instruments operate in Figure D is a schematic of the Michelson Interferometer. Infrared spectroscopy is also finding a place in the environmental analysts' A schematic diagram of a UV-Vis spectrophotometer is shown in Figure.11. IR region..
