Short Wave Pass Edge Filters

Short Wave Pass Edge Filters

Short Wave Pass (SWP) edge filters represent Andover's solution for precise spectral control in shorter wavelength regions.
These filters employ first-surface dielectric coatings to achieve sharp transitions between transmission and blocking regions, delivering superior performance compared to conventional colored glass filters.
Designed to transmit shorter wavelengths while effectively blocking longer ones, these filters provide excellent spectral discrimination across the 300-1000nm range, making them ideal for demanding optical applications requiring precise wavelength selection.
