Filters are flexible

Custom, variable, metallic neutral-density filters and geometric beamsplitters with variable beamsplitting ratio have transmission and reflection defined by a computer-generated geometrical beamsplitter. Software and photolithographic fabrication allow flexibility in achieving linear and nonlinear patterns in different sizes for prototype and serial quantities.

Custom, variable, metallic neutral-density filters and geometric beamsplitters with variable beamsplitting ratio have transmission and reflection defined by a computer-generated geometrical beamsplitter. Software and photolithographic fabrication allow flexibility in achieving linear and nonlinear patterns in different sizes for prototype and serial quantities. A variety of substrate materials such as fused silica are available. The optical density ranges from nearly zero to four or five, depending on customer specifications.
