Frequently Asked Questions

The Dye Handpiece is used in medical cosmetology for the treatment of vascular diseases such as port-wine stains, hemangiomas, telangiectasia, rosacea, spider nevi, acne, scars, stretch marks, dark circles around the eyes, skin rejuvenation, and pseudofolliculitis.

The Dye Handpiece works by using solid dye bodies as the laser medium to convert the laser wavelength from 532nm to either 650nm or 585nm, depending on the model. It is connected to the laser output terminal of the laser beauty instrument to facilitate medical cosmetology procedures.

The Dye Handpiece features a compact structure, convenient replacement, stable performance, and the ability to easily achieve the output of new wavelengths.

The available nanosecond models are HP650-DYE-NHN, HP585-DYE-NHN, HP650-DYE-NHS, and HP585-DYE-NHS. They have output wavelengths of 650nm or 585nm, efficiencies of 40% or 60%, spot sizes of 2.5+/-0.5mm, and a service life of ≥20,000 times.

It is recommended to apply the product according to the usage conditions in the attached table to ensure its lifespan reaches 20,000 times. Additionally, the input light should not contain light of other wavelengths, such as the 1064nm laser.

For nanosecond models, the input wavelength should be 532nm, input energy 200mJ, pulse width 8ns~10ns, energy distribution flattop light, spot diameter Φ12~13mm, and frequency 1Hz. For picosecond models, input energy is 100mJ and pulse width 350ps~500ps.

The nanosecond models have higher efficiency (40% or 60%) and smaller spot sizes (2.5+/-0.5mm), while the picosecond models have lower efficiency (20% or 30%) and larger spot sizes (3.0+/-0.8mm or 4.5+/-0.8mm). Both model types have a service life of ≥20,000 times.
