Import 308nm Excimer Laser Equipment — Buy in Bulk from Supplier in China

The 308 nm excimer laser system from Wuhan CAS Keli Electrooptical Technology is a gas-discharge ultraviolet laser built around xenon chloride (XeCl) chemistry, producing coherent emission at 308 nm. The equipment is developed by scientists from the Chinese Academy of Sciences and is targeted at medical dermatology, cosmetic procedures, and industrial precision marking applications. The supplier describes a compact form factor designed for integration into existing clinical or production workflows, though specific dimensions, beam parameters, and output power ratings are not provided in the source material. The 308 nm wavelength corresponds to 4.03 eV photon energy, suitable for precise ablation of biological tissue and certain polymers without deep thermal diffusion.

XeCl excimer lasers typically operate with a gas mixture of xenon, chlorine, and a neon or helium buffer at pressures of several atmospheres, with pulse durations in the nanosecond range and repetition rates variable from single shot to hundreds of hertz depending on the power supply and cooling architecture. The supplier mentions high stability and accuracy in laser output, but does not quantify beam pointing stability, pulse-to-pulse energy variation, or mode structure. Standard 308 nm excimer systems for dermatology deliver fluences of 50 to 200 mJ per square centimetre at the treatment plane with spot sizes from 2 mm by 2 mm to 20 mm by 20 mm. Buyers should determine whether the offered system uses a fixed or adjustable beam delivery optic and whether fibre optic or articulated arm coupling is provided.

Medical applications cited include psoriasis and vitiligo treatment, where 308 nm UV-B phototherapy offers targeted dosing with reduced exposure of unaffected skin. Industrial uses encompass micromachining of polymers, thin-film patterning, and marking of temperature-sensitive substrates. The supplier mentions flexible minimum order quantities and references ISO and CE certifications without providing certificate numbers or scope. Packaging is described as tailored for safe delivery, with FOB and CIF shipping options noted. Buyers should confirm with the supplier the exact output energy per pulse, repetition rate maximum, beam delivery configuration, and cooling system requirements, as these determine clinical throughput and installation infrastructure needs.

Wuhan CAS Keli Electrooptical Technology Co., Ltd. is located in the Economic Development Zone of Wuhan, Hubei Province, China, with the postal address listed as 430074. The supplier indicates an affiliation with the Chinese Academy of Sciences through its founding scientists, though the exact nature of this relationship, whether spin-off, licenced technology, or informal collaboration, is not detailed. The company holds an imported supplier tier and a harbour trust tier, with a zero percent response rate and no average response hours recorded in the platform data. No information is provided on year of establishment, registered capital, employee headcount, annual revenue, or named clientele.

The source description makes claims of ISO and CE certification, competitive trade terms, flexible minimum order quantities, and global reach, but provides no verifiable documentation or specific figures. Buyers should independently verify the supplier's business licence, ISO 9001 or ISO 13485 certification status for medical devices, and CE marking documentation including the notified body identification number. The mention of scientists from the Chinese Academy of Sciences suggests potential technical depth, but this should be confirmed through direct communication regarding research publications, patent holdings, and the specific roles of named individuals in product development.
