How ESI Developed A New Cost-Saving Design Methodology For Laser Systems

Electro Scientific Industries (ESI), a creator of laser-based manufacturing solutions, developed a new, cost-saving methodology for laser systems involved in computer memory chip repair.

ESI discovered a simple relationship between a laser beam’s astigmatism, asymmetry, and extremal ellipticity propagating through an optical system. Validated by OpticStudio, this discovery enables a trade-off between astigmatism and asymmetry to create a round beam with sufficiently low ellipticity. As a result, ESI can relax laser specification requirements, reducing manufacturing costs of their ultra-precise micromachining systems. Learn how ESI proved this theory and its implications for laser design.
