2940nm Hexagonal Microlens Arrays Honeycomb Homogenizer Product Overview
The 2940 nm Honeycomb Homogenizer is an optical component typically integrated within a 2940 nm Er:YAG fractional laser system utilizing picosecond-domain technology. It consists of numerous tiny, hexagonally arranged micro-lenses. Due to this honeycomb-like structure, it is also commonly referred to as a honeycomb lens.
When a 2940 nm laser beam passes through the Honeycomb Homogenizer, it functions like a traditional focusing or field lens, optimizing the fractional laser beam. Its micro-lenses perform secondary focusing on the pre-existing laser micro-spots, concentrating them into smaller points. This significantly increases the energy density delivered to the skin, enabling deeper and more precise treatment.
Moreover, by adjusting the relative distance between the homogenizer and the skin surface, the focal depth of the laser micro-spots within the skin can be precisely controlled.
This 2940 nm hexagonal refractive micro-lens array can also be paired with a 2940 nm diffractive optical element (DOE). In this configuration, the slightly diverging micro-beams generated by the DOE are collimated and delivered in a more uniform and parallel manner, enhancing the predictability and safety of aesthetic medical treatments.

2940nm Hexagonal Microlens Arrays Honeycomb Homogenizer Aesthetic Application:
In 2940nm Er:YAG fractional laser systems, laser output often suffers from uneven spot size and locally excessive energy. Directly applying the laser to the skin or material surface can result in uneven treatment depth, localized burns, or unstable processing. Honeycomb homogenizers address this issue by evenly distributing laser energy.
A honeycomb homogenizer is installed in the laser light path, typically between the light source and the DOE or focusing optical system. After passing through the honeycomb homogenizer, the originally slightly divergent or unevenly intensity microbeams are redistributed into a uniform, flat-topped array of microspots. The DOE or focusing system then delivers the laser to the target surface. The relative distance between the honeycomb homogenizer and the skin or material surface can be adjusted to precisely control the focal depth and coverage of the laser spot.
