7ISW15 Series Double-Grating Scanning Monochromator/Spectrometer (patent)
Features
  • Asymmetrical Czerny-Turner optical path design, eliminating aberrations, which can improve spectral line symmetry and enhance optical resolution.
  • Second dispersion removal design effectively reduces stray light.
  • Flexible configuration allows for the use of multiple gratings according to specific demands.
  • The monochromator is equipped with RS232 and USB interfaces. Through computer control, grating conversion, filter replacement, and wavelength scanning can be achieved, enabling fully automatic wide spectrum testing. USB support allows for hot plug, offering plug-and-play convenience and fast transmission rates.
  • The entrance port can be used with various light sources produced by our company and can be equipped with a fiber optic entrance connector.
  • It can be connected to any single-point detector and other accessories manufactured by our company. It can also be connected to line arrays and array detectors for spectrograph use.
