Why Use a Homogenizing Mirror?

In most laser applications, the Gaussian energy distribution (high intensity in the center, low at the edges) can lead to uneven processing, such as over-melting in the middle or insufficient heating at the periphery. IREEDA Homogenizing Mirrors are engineered to reshape the energy profile, delivering a "top-hat" intensity distribution. This is essential for precision laser cleaning, stripping, and large-area surface processing

IREEDA Homogenizing Mirror

Highlights

Premium Beam Homogenization: Specifically designed to convert standard Gaussian laser beams into uniform Flat-top beams, eliminating hot spots and ensuring consistent energy distribution across the entire spot area.
Ultra-High Reflectivity (R > 99.8%): Features state-of-the-art dielectric HR coatings at 1064nm. Minimizes insertion loss and prevents thermal deformation in high-power fiber laser systems.
Superior Substrate Quality: Available in high-clarity K9 (BK7) for cost-efficiency or Fused Silica (Quartz) for extreme thermal stability and high laser damage thresholds (LDT).
Precision Curvature Design: Offered with standard large radii of R4000 or R7000, meticulously polished to ensure precise wavefront control and excellent far-field homogenization.
Industrial Durability: Built to withstand harsh industrial environments. Optimized for laser cleaning, welding, and surface treatment where long-term stability is critical.
