Filter Design
Long and Shortpass filters, also known as “edge filters”, have a wide variety of applications throughout many industries. Often used for precise discrimination of adjacent wavelengths, these filters are crucial in controlling signal-to-noise and instrument sensitivity. Long and shortpass filters are fully customizable for use in reflection or transmission configurations and also have functionality for use as beamsplitters or combiners.
