Quartz optical coating filter

 Quartz optical coating filters are all made of high-quality quartz hard coating technology ,The commonly used specification is a 60mm diameter disc, which is fixed by M62 thread and can be stacked in multiple layers. Can be used with the full range of light sources of China Education Golden Resources.
