Yellow quartz UV-d model series, surface yellow, dark yellow section. I produced a yellow deep yellow and light yellow quartz tube has two colors to choose from. Yellow quartz tube can not completely filter out all visible light in the ultraviolet, to avoid occurrence of material produced color centers and light distortion, yellow quartz tube to reduce the corrosion of silver reflective layer, substantially improve the efficiency of the laser occurs. Yellow quartz tube is laser technology, laser generator, the main components core equipment important material of the optical pumping.
