WebThe UV-Vis spectral range is approximately 190 to 900 nm, as defined by the working range of typical commercial UV-Vis spectrophotometers. The short-wavelength limit for simple UV-Vis spectrometers is the absorption of ultraviolet wavelengths less than 180 nm by atmospheric gases. Purging a spectrometer with nitrogen gas extends this limit to 175 … WebUV–visible spectroscopy of microscopic samples is done by integrating an optical microscope with UV–visible optics, white light sources, a monochromator, and a sensitive …

WebSep 25, 2015 · To be sensitive to wavelength, you need to disperse the light, and that means a monochromator. Whether you use exit slits and a single detector and scan the wavelength, or use a position sensitive detector to measure the spectrum at once, is up to you. – Jon Custer Sep 25, 2015 at 20:59 Add a comment 1 Answer Sorted by: 1 WebGENESYS UV-Vis Spectrophotometer Free Trial Programs*.
