Selection Guide

Powell lens results depend on laser parameters and the real optical path. For best line uniformity, select in this order: operating band → design wavelength → 1/e² input spot diameter → fan angle → mechanical size → material and coating.

Different combinations of spot size, wavelength, and fan angle change the final line profile. When requesting a quote, please provide complete parameters. Special sizes, angles, or bands can be matched by our engineers. Final specifications follow the datasheet and measured results.
