Top Hat Beam Shaping Lenses

FBSR beam shapers generate round homogeneous Top Hat spots. Each FBSR is made for a fixed input beam diameter with a ±5% tolerance. Lenses for wavelengths and beam diameters other than standard, can be produced on request.

FBSL beam shapers generate narrow and homogeneous line spots. FBSL generates a Top Hat profile along the line, while across the line the shape is Gaussian to allow the smallest line width. Length and width ratio is around 1.6 : 1 @ 1/e², 2.2 : 1 @ FWHM.

FBS2 beam shapers generate small and homogeneous square Top Hat spots in the focal plane. Each FBS2 is made for a fixed input beam diameter with a ±5% tolerance. Lenses for wavelengths and beam diameters other than standard, can be produced on request.
