Honeycomb Lens: Features and Maintenance
A honeycomb lens is a hexagonal micro-lens array, composed of hundreds of hexagonal micro-lenses according to certain rules. Since the shape of the small hexagonal lenses is similar to the shape of a honeycomb, the arrangement of the output light spots also forms a honeycomb shape — hence its name.
After years of development, the honeycomb lens on the market has been standardized. The standard lens has a diameter of 16 mm, a thickness of 2 mm, and a focus of 40 mm. It consists of hundreds of hexagonal micro-lenses with a subunit size of only 1000 μm.
After the laser beam passes through the honeycomb lens, it generates a hexagonal array of dots. The size of each laser dot is adjustable.
Applications in Beauty Industry
A common application of honeycomb lenses is in the beauty industry. For this usage, important features of the honeycomb lens include:
- Focusing the laser energy into the “Honeycomb Instantaneous Lens” reintegrates the energy.
- The lens focuses 70% of the high energy to 130 honeycomb center points to form a honeycomb lattice that acts on the skin.
- The laser energy released from the central point of each honeycomb can be as high as 20 times more intense.
- The honeycomb shock effect shatters the melanocytes of the epidermis and spreads to the deep dermis.
Cleaning and Maintenance
A honeycomb lens is a relatively precise product. The lens is manufactured with advanced coating technology, but the coated surface can be easily damaged.
Cleaning and maintenance of the lens can prolong its service life. However, improper cleaning can damage polished surfaces as well as any specialized overlays on substrates or lenses. Such damage can degrade performance in all applications.
Customized Honeycomb Lens cleaning and maintenance tips:
- Hold the edge of the customized honeycomb lens. Use wooden, bamboo and plastic tools to handle the lens will reduce the chance of damage to the lens. A handheld vacuum pen can be used for small lenses. Do not handle the lens with metal tools or pliers.
- Never touch the lens surface with your fingers, because moisture from the fingers can sometimes damage the coating on the lens. Touching a finger on the lens surface for a long time can create a permanent stain. Avoid touching the lens surface even if you are wearing gloves.
- Place the lens on a soft surface, especially if the optical surface is convex. Placing a lens on a hard table surface will scratch the lens surface.
- When not using the lens system or assembly, cover the lens to protect the optical surface from damage.
- When storing a customized honeycomb lens, wrap each lens individually in a clean, soft lens box, and place in a safe place. Never put unwrapped lenses together in a box or bag, as they can be damaged by contact with each other. Never place them under heavy objects.
