InnPho's Flat-Top Beam Expandersconvert a Gaussian laser beam input into an output that has a flat-top profile. The conversion is caused by an Engineered DiffuserTM, manufactured by RPC Photonics, Inc.
Feature:
● Spectral Range: 350 nm to 2 μm
● Cross section uniformity: ± 5-10% (neglecting speckle)
● Laser damage threshold: 20 J/cm2, 1054 nm, 1 ns pulse
Optimum performance of the apodizing element (Engineered DiffuserTM) is achieved when the input beam diameter is 3-4 mm, using our GCE-9.
