Cylindrical Lenses
Featured Product from Avantier Inc.
Avantier manufactures high-precision cylindrical optics designed for the rigorous demands of laser beam conditioning, spectroscopic imaging, and aerospace metrology. By integrating advanced manufacturing with proprietary CGH (Computer-Generated Hologram) interferometry, we ensure every lens—from standard plano-convex to complex aspheric profiles—delivers the exact wavefront quality your application requires.
Unlike spherical lenses, a cylindrical lens is highly sensitive to angular orientation. A misalignment of even a fraction of a degree can introduce unwanted residual astigmatism, degrading the beam quality (M2) significantly.
