This site is maintained by Hangzhou SG Electronic Technology Co., Ltd. It covers portable Q-switched Nd:YAG complete machines. We manufacture in Hangzhou, China.
It is a category guide, not a shop. Pages list only specifications, wavelengths and applications that appear in the product file. Prices are not published, and parameters with no source figure are left off entirely.
Picosecond lasers, IPL and diode hair-removal machines have their own category sites and are not republished here.
Free OEM / ODM Development for Distributors
Exclusive machine design, handpiece design, menu interface and logo — all yours.
SG quotes a fair cost for every stage of the project. The buyer pays the development fee in one payment or in stages. Both sides then agree on machine and accessory prices in a pricing agreement. The full development fee is returned as discounts on the buyer's continuing machine orders. When orders of one model, or of similar models, reach 10 units, SG gives one complete machine free of charge.
