JY-7ILD series deuterium lamp light source

Deuterium lamp light sources are mainly used for ultraviolet radiation, reaching the vacuum ultraviolet limit of 195nm. The shorter the wavelength, the higher the brightness, and below 360nm, the radiance is higher than that of general halogen lamps. The JY-7ILD30 deuterium lamp light source produced by our company is equipped with long-life deuterium lamp bulbs indoors, which can be replaced by users themselves. When used in conjunction with our company's stable current power supply JY-7IPD30, the stability is better. It can be used as an independent excitation light source for ultraviolet and fluorescent light sources, or used in conjunction with our company's monochromators, spectrometers, sample chambers, filter wheels, etc. to form various application systems.
