Neutral density filter sets
from AndoverAbsorption and metallic-coated neutral density (ND) filters. The metallic coated type ND filters employs a combination of absorption and reflection to reduce the intensity of lights. The absorptive filters feature the ability to minimize back-reflections and scattered light. They are therefore ideal for calibration.
