Since our inception, we are serving in the industry as trustworthy manufacturer and supplier of UV Spectrophotometer. We integrate these equipments by making use of high graded components sourced after a keen market inspection. Our provided stock of UV Spectrophotometer use two light sources one is deuterium (D2) lamp that is applicable for ultraviolet light and the second is tungsten (W) lamp that is useful for visible light.
- Fine measurement attributes
- Technically assorted
- no unwanted higher orders of diffraction
The UV-Visible spectrophotometer uses two light sources, a deuterium (D2) lamp for ultraviolet light and a tungsten (W) lamp for visible light. After bouncing off a mirror (mirror 1), the light beam passes through a slit and hits a diffraction grating. The grating can be rotated allowing for a specific wavelength to be selected. At any specific orientation of the grating, only monochromatic (single wavelength) successfully passes through a slit. A filter is used to remove unwanted higher orders of diffraction. (Recall the experiment you did last semester on Atomic Spectra) The light beam hits a second mirror before it gets split by a half mirror (half of the light is reflected, the other half passes through). One of the beams is allowed to pass through a reference cuvette (which contains the solvent only), the other passes through the sample cuvette. The intensities of the light beams are then measured at the end.
