Features:

  • Nonsymmetrical level Czerny-Turner beam path and coma correction design can improve symmetry of spectral lines and optical resolution.

  • Eliminating secondary dispersion is designed to restrain stray light.

  • Optional multi gratings are available.

  • The precision worm & gear structure guarantees the high accuracy and repeatability.

  • Operations of grating switching, light filters changing and wavelength scanning are controlled by computer via RS232 interface or USB interface.

  • Nitrogen connector is available for UV and NIR testing.

  • The standard beam entrance is compatible with our light sources and fiber interface.

  • The standard beam outlet is compatible with our single-point detector and other accessory.

  • Widely are applied in teaching, scientific research, luminosity, chromaticity measurement, coating machine, air pollution surveillance and so on.

  • Optics chamber and mechanical drive chamber are separated to reduce stray light and pollution to optical components.

 


Description:


This series Spectrometers use two gratings and optional multi gratings are available. By RSR232 interface or USB interface, the Spectrometers can be controlled via computer to switch grating, change light filters and scan wavelength. The Spectrometers guarantee the high accuracy and repeatability by the precision worm & gear structure.
