Product Description
Payment & Delivery



  • 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.

  • Using 1200g/mm grating, the wavelength range is 0-1100nm to cover silicon detector's range.

  • 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.

  • The sine drive system uses precise grinding guide screw to guarantee the high accuracy and repeatability.

  • The ultra wear-resisting linear guide rails ensure steady movement, long life and low noise.

  • Manual monochromator has wavelength counter, the wavelength is controlled manually.

  • They are widely 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.




Our monochromators use 1200g/mm grating, and the wavelength range is 0-1100nm. Czerny-Turner design and coma correction deign can improve symmetry of spectral lines and optical resolution.

Precision grinding guide screw provides high accuracy and repeatability. The standard interface design makes the monochromators are compatible with light sources, detector and other accessories.

The monochromators are widely used in teaching, scientific research, luminosity, chromaticity measurement, coating machine and air pollution surveillance.
