Measuring Range


Optical system

·Optical system: Pashen-Runge, Roland circle optical structure, Roland focal length: 500mm

·High-performance holographic diffraction grating, Grating notching 1800L/mm & 2700L/mm

·Optical resolution: 0.006nm

·Spectral range: 200-800nm

·Double chamber system:

Short wave chamber wavelength: 200~470nm

Long wave chamber wavelength: 470~800nm;

·Both roland circle and the host machine are equipped with a constant temperature system to

maintain constant temperature independently, 40±1°C; the constant temperature is

adjustable, which is effectively suitable for too high or too low environment temperature

The linear array of multiple CCDS is arranged in a Roland circular shape, which realizes

continuous and simultaneous detection of the whole band, and facilitates later

development of other elements

·8 high performance CCD detectors, each CCD with 3648 pixels

·Ultraviolet band spectral enhancement detection technology, enhances the ultraviolet band

light intensity, and prolongs the life

Excitation light source

·Bidirectional high performance excitation light source, 14000V ignition pulse, digital discharge

parameter setting, digital pulse generator, digital offline pulse control

·Dual-phase zero-crossing signal detection technology, avoiding high-voltage spark

electromagnetic compatibility interference, and improving voltage stability

Excitation chamber

·Rod electrode holder for automatic adjustment of electrode pole distance device, ensure that

the height of electrode spacing is consistent for all measurements
