✦ Synopsis

Laser beams get flat-tops Newport Corporation's Refractive

Beam Shaper converts a laser beam with a Gaussian profile into a collimated, flat-top beam that propagates over large distances without variation in power, intensity, or uniformity. The beam shaper relies on low-dispersion refractive optics and produces no hard edges, speckles, or diffraction effects. It functions over a large bandwidth, from far infrared to deep ultraviolet, and has a near 100% conversion efficiency. The 910A Spatial Filter Series from Newport is suitable for all of its Mand L-Series objective lenses and 910PH-Series mounted pinholes. The spatial filters combine five-axis alignment with high stability.
