The supplier sells Asphericon, AdlOptica πShaper and other beam shapers. Aspheric a|TopShape, a|AiryShape and a|SqAiryShape modules efficiently convert Gaussian beams to circular/square flat-top profiles, with precise manufacture for quality/stability across laser applications. a|TopShape converts a collimated Gaussian to a slightly enlarged(M≈1.5), collimated uniform flat-top, with compact design, high optical quality and≥90% uniformity. It spans320–2500nm and accepts10mm input diameter±10%. Standard reach is0.3m; LD reaches1.5m; LDX maintains uniformity up to3m by adjusting input diameter/divergence. Since smaller beams shorten effective reach, LD/LDX suit small diameters; relaxed uniformity permits longer reach. Referenced intensity profiles are at100,1000,3000 and4000mm. LD reaches95% uniformity within1.5m; changing input diameter gives LDX94% within3.2m. TopShape design wavelengths are355,632 and1064nm; LD/LDX offer355,405,532,632,780 and1064nm. Flat-tops improve cutting edges/uniform illumination over centrally peaked Gaussian beams in material processing, inspection and fluorescence microscopy. a|AiryShape covers300–1600nm and combines with focusing lenses to form focused circular flat-tops/rings, integrating compactly. a|SqAiryShape similarly forms focused square profiles, described as flat-top and ring spots, over300–1600nm. Its17.3mm length fits existing setups; adding a focusing lens greatly shortens working distance. Combining a|BeamExpander, a|SqAiryShape and a200mm lens reduces total assembly length25%. Cached figures describe normalized z profiles within±1.5mm of the waist and2D/cross-section intensities at different planes for a|AiryShape at635nm. It creates flat-tops at focus and varied profiles at other distances; quality depends on well-collimated input with minimal wavefront aberration. a|SqAiryShape figures at1064nm span±6mm around the waist, giving square flat-tops and other fourfold-symmetric profiles; it likewise requires quality collimated input. BeamTuning's Airyshape supports broad wavelengths. a|TopHat Tune Circle forms precise circular flat-tops1–10mm in diameter for processing/other applications. Varied focusing focal lengths adjust distance/diameter while preserving uniformity. It covers300–1600nm and integrates with BeamTuning; referenced simulations show uniform intensity. A30mm outer diameter fits standard mounts such as a|VariMount, then connects to a focusing lens. Example50,75 and100mm lenses change working distance/spot diameter; a graph relates flat-top diameter to lens EFL. A780nm design simulation with a focusing lens illustrates fully uniform intensity, important for processing, cutting and consistent energy delivery. Standard mounting and plug-and-play lens connection require little setup, improving efficiency; physical construction supports long-term durability/reliability.

The Top hat beam shaper is developed and manufactured by Canada's Osela. It effectively converts a free-space or fiber-delivered laser beam into a uniform, slowly varying profile without high-frequency noise. The TH model has no internal imaging lens and requires an external imaging-lens system. Applications include flow-cytometric cell-count monitoring, DNA sequencing, micromachining, confocal microscopy and others.
