Introduction: The monochromator decomposes the composite light into a series of high-purity monochromatic light. It is mainly used for quantitative and qualitative analysis of light source characteristics, solution concentration, light effect and optical properties of transparent substances. Product application: Among them, grating monochromator is widely used. In scientific research, production, quality control and other links. Whether it is penetration absorption spectroscopy, fluorescence spectroscopy, or Raman spectroscopy, how to obtain single-wavelength radiation is an indispensable means. Features: 1. The instrument is small in size; 2. The sinusoidal mechanism of the instrument is isolated from the optical chamber, which effectively reduces the stray light and avoids the pollution of the surface of the optical parts caused by the chronic volatilization of the lubricating oil in the mechanical system; 3. The instrument is equipped with a mechanical counter, which can directly read the wavelength of monochromatic light, and is also equipped with a stepping motor. Technical parameter: Focal length: 100mm Wavelength range: 330nm ~ 900nm (Users can choose grating according to their needs, and extend to a certain band within the range of 190nm ~ 20μm.) Wavelength accuracy: ±1nm (1200 lines/mm grating) Wavelength repeatability: 0.5nm (1200 lines/mm grating) Resolution: ≤1nm (1200 lines/mm grating, measured by the spectral line half-width method according to the national standard) Stray light: ≤1×10-3 (He-Ne laser, measured at 632.8±8(nm)) Slit: There are four options: 0.1mm, 0.5mm, 1mm, 2mm Dimensions: 145×145×120mm3 (excluding motor)
