Profile: ZOLIXINSTRUMENTS CO.LTD is a manufacturer of fine mechanics, motorized micro-positioning stages, and precision light measuring instruments. We offer optical spectroscopy systems and components including monochromators, spectrographs, light sources such as tungsten-halogen light source, xeono light source, SiC infrared light source, and the detectors. We are a designer of custom optical system including emission, absorption, transmission spectroscopy analysis system, photodevice detector spectroscopy analysis system, fluorescence, Raman spectroscopy analysis system, and solar cell spectral response/QE/IPCE measurement system. The modular ZLX-FS fluorescence spectrometer is designed for the precise measurement of excitation and emission spectra from solid or liquid samples, and has found application in many fields such as chemistry, physics, biology, medicine, and environmental monitoring. The ZLX-ES series spectro-radiometer systems are designed for the accurate measurement of the radiant power emitted from a light source as a function of wavelength. The ZLX-AS system is designed for high quality measurements with excellent stray light performance of absorption, transmission and reflectance, from a wide range of solid and liquid samples.
