The TopShape is a beam shaper that transforms collimated Gaussian beams into collimated top hat beams. It is distinguished by its compact design and outstanding optical quality (beam uniformity < 0.1). The beam shaper covers a wide spectral range (320–1600 nm), accepts different input beam diameters and generates a stable beam profile for at least 300 mm. Using the LongDistance (LD) version , even homogeneous beam profiles can be achieved at a working distance of up to 1.5 m. With the new a|TopShape LDX, the beam profile can be shifted to large working distances of up to 3 m.
