glassvisiblebeam shaping

Gaussian to Top-Hat Beam Shapers are special optical lenses used to distribute energy of Gaussian beam to Top Hat profile. We offer uncoated, VIS or IR coated Gauss-to-Top hat beam shaping lenses. Lens Specifications: Material: LF5 Schott glass Recommended operation wavelength range: 400-1500 nm n= 1.5659 @1060 nm, n= 1.5848 @ 546 nm, n= 1.6192 @ 365 nm Lens diameter: 12.0 +0.0/-0.1 mm Thickness: 4.0 +/- 0.1 mm Clear aperture: dia 11.0 mm Beam energy distribution efficiency: >95% of input energy within Top Hat profile Beam homogenity: ±5% (rel. to average intensity within top hat) Damage threshold (uncoated): >3J/cm2 @ 532 nm, 10 ns Mounted in to 1” ring holder.
