Overview
IREEDA Precision Microlens Arrays (MLA) are high-end optical components designed for sophisticated beam shaping and light field control. Featuring a meticulously engineered hexagonal (honeycomb) structure, these arrays provide the highest possible fill factor to ensure exceptional light utilization and beam uniformity.
Equipped with a triple-band AR coating (R<0.1%), they are perfectly optimized for multi-wavelength laser systems (1064nm, 532nm, and 650nm), making them the industry standard for high-power laser homogenization and Shack-Hartmann wavefront sensing.
Highlights
- Superior Homogeneity : Transforms non-uniform Gaussian laser beams into ultra-stable "Flat-top" profiles with uniformity >95%.
- Hexagonal Honeycomb Design: Optimized hexagonal grid provides superior fill factor compared to square arrays, minimizing zero-order diffraction and stray light.
- Triple-Band AR Coating : Advanced coating achieves R<0.1% at 1064nm, 532nm, and 650nm simultaneously, ensuring maximum transmission and zero ghosting.
- High Power Resilience : Available in Synthetic Fused Silica (Quartz) to handle high-peak-power pulses in industrial laser cleaning, welding, and medical systems.
- OEM & Custom Patterns : Standard 16/20mm diameters available. We support custom lens pitch, focal length, and substrate geometry to fit your optical assembly.

FAQ
1. Q: What is the benefit of a hexagonal microlens array over a square one?
A: Hexagonal arrays have a higher fill factor and a more circular symmetry. This results in better light collection efficiency and a more uniform, rounded beam profile in the far field, which is ideal for laser processing.
2. Q: Can these arrays be used with high-power UV lasers?
A: Yes, when using the Quartz (Fused Silica) substrate, the array can handle high-power UV and IR lasers with a very high damage threshold, preventing thermal lens effects.
3. Q: Do you support custom focal lengths for individual microlenses?
A: Absolutely. We can customize the pitch (size of each small lens) and the radius of curvature (focal length) to meet your specific beam shaping requirements.
