Neutral Density Filters
Neutral Density (ND) Filters reduces the intensity of incoming light spectrum equally. ND Filters can either reduce the intensity by absorbing or reflecting the incoming light spectrum. They are used extensively in laser and imaging applications as there is a need for ND filters to prevent excessive damage to the sensors or optical components.
Simtrum Provides a variety of ND Filters such as: Absorptive ND Filters, Reflective ND Filters, Variable ND Filters, etc.
