Features:
1. Adopted high-class grating with wholly hermetic light path design, to ensure the instrument has the super low stray light.
2. Real-time monitoring the lifetime of Deuterium lamp and Tungsten lamp with advanced system.
3. With GLP self-check function, check the wavelength accuracy and Photometry accuracy.
4. Wavelength calibration, wavelength setting, change lamp source and dark current calibration automatically.
5. With Si02 coating optical mirror, reducing the pollution from outside fully.
