Absorptive neutral density filter
Neutral density filters are commonly used in imaging optical systems, lasers, machine vision, spectral measurement and other fields, its used to avoid damage to camera sensors or other optical components caused by strong light. Neutral density filters can absorb or reflect the untransmitted portion of the light to evenly reduce the transmittance of a portion of the spectrum.
VR optics can offer absorptive neutral density filters of various materials and sizes, OD from 0.1 to 4, as well as various coatings.
