WebFor example, a linear spatial filter that emphasizes high spatial frequencies (high-pass) tends to sharpen the edges of an image, while a linear spatial filter that emphasizes low spatial frequencies (low-pass) will tend to blur the image and reduce noise. WebSimilarly, for optimized coupling into a single mode fiber the spot size of the focused beam must be less than the mode-field diameter of the fiber. Spatial Filter Systems. Many applications, such as holography, require a beam with uniform intensity. The KT310 spatial filter is ideal for producing a clean, spatially uniform, Gaussian beam.
