Linear Apodizing Filters
Linear Apodizing filters are customizable density gradient filters that have constant density in one direction and variable ND filter in the other direction. Two types: dark in center to clear on the outer edges or clear in center to dark on the outer edges. These filters are used to eliminate undesirable intensity variations in optical systems. There are two basic types of these filters: 1) Dark in the center to clear on the outer edges, or 2) Clear in the center to dark on the outer edges.
Custom sizes and densities are available upon request.
