Ultra low stray light: excellentThe C-T monochromator optical system, advanced electronic system, ensures an ultra-low stray light level of better than 0.03%, meeting the measurement needs of users for high absorbance samples.

High quality components: The core components are made of high-quality imported parts to ensure the stability, reliability, and long life of the instrument. The core light source components are sourced from Hamamatsu, Japan（HAMAMATSU's long-life deuterium lamp ensures a working life of over 2000 hours, greatly reducing the maintenance frequency and cost of replacing light sources on a daily basis.

Long term stability and reliability: The optical dual beam optical system design, combined with real-time digital proportional feedback signal processing, effectively offsets the signal drift of light sources and other components, ensuring the long-term stability of the instrument baseline.

High wavelength accuracy: The high-level wavelength scanning mechanical system ensures superior performanceThe wavelength accuracy of 0.3nm and the wavelength repeatability better than 0.1nm are achieved through the instrument's built-in spectral characteristic wavelength for automatic wavelength detection and correction, ensuring the long-term stability of wavelength accuracy.

Convenient replacement of light source: The instrument can replace the light source without removing the housing. The light source switching mirror supports automatic search for the best position function. The direct insertion deuterium tungsten lamp design eliminates the need for optical debugging when maintaining and replacing the light source.
