What is the difference between DOE and MLA?

A DOE (Diffractive Optical Element) and MLA (Micro-Lens Array) are two different optics used to split laser energy into multiple micro-spots. A DOE creates a highly uniform, evenly distributed grid of micro-beams with consistent spacing and energy, making treatments more controlled and predictable. An MLA uses many tiny lenses to split the beam, but can produce less uniform patterns with slight variations in spot intensity. In short, DOEs offer greater precision and consistency, while MLAs are simpler but less accurate.
