The absorption neutral filter can reduce the light amount of visible light or YAG laser (1064nm). Because it is an absorption filter, there is little stray light caused by reflection, and the characteristics of transmitted light will not change greatly with the decrease of light quantity. The transmittance classification is meticulous, which can reduce various light quantities, and the light quantities can be fine-tuned by combining several filters. WNZAB absorbent neutral filter has no coating on its surface.
