- Excimer Info
- An excimer laser premix is a multi-gas mixture, dedicated to the generation and /or production of a single wavelength. In order to achieve maximum safety, improve reproducibility, and guarantee optimum laser performance, the use of a premix has become a laser industry standard.
Linde Gases premixes provide the following advantages:
- Very low percentages of toxic, corrosive halogen gases
- Precise gas mixtures analyzed and guaranteed to each manufacturer's specifications
- Minimal space requirements
- Lowered cylinder costs: shipping, storage, rental
- Fewer gas lines and gas handling equipment
- Superior reproducibility
The term "Excimer" refers to the rare gas / halide molecule. There are four wavelengths (spectral lines) that can be generated from Fluorine laser gas mixtures and two generated from Hydrogen Chloride laser gas mixtures.
- Argon is a rare atmospheric gas which is colorless, odorless, tasteless, and nontoxic. It is considered extremely inert and forms no known chemical compounds. The concentration of argon gas in the atmosphere by volume is 0.93%. Argon gas has numerous applications, including neon signs, lasers, incandescent and fluorescent lamps, electronic tubes, window insulation, welding, and semiconductor applications. Numerous purities of argon gas are available for specific industrial purposes. ::: Argon Brochure
- Fluorine Excimer
- Excimer lasers are multi-gas lasers. Output wavelength is a function of the rare gas / halogen combination. Excimer is the name of the rare gas / halide molecule. There are four wavelengths (spectral lines) that can be generated from fluorine laser gas mixtures. ::: Fluorine Excimer Brochure
- Helium is a rare atmospheric gas which is colorless, odorless, tasteless, nontoxic, nonflammable, and only slightly soluble in water. The concentration of helium gas in the atmosphere by volume percent is 5.24 x 10-4. Helium gas is principally shipped and used in either gaseous or liquid form for nuclear reactors, semiconductors, lasers, light bulbs, superconductivity, instrumentation, medical applications, cryogenics, MRI and R & D laboratories. ::: Helium Brochure
- Vision Correction Gases
The use of lasers in ophthalmology has been around since the 1970’s for conditions like glaucoma and retinal tears, however the existence of LASIK for vision correction is relatively new and in fact it was not approved in the United States until late 1990’s by the Food and Drug Administration. Once approved, LASIK surgery for vision correction has taken off and has been extremely popular with people seeking alternatives to glasses and contacts.
According to the FDA, over 600,000 LASIK eye surgeries are performed in the United States each year. Spectra/Linde’s involvement with the vision correction market has been around since the beginning and in fact it was Spectra/Linde’s hard work with the industrial Excimer OEM’s that paved the way for Spectra/Linde to enter the vision correction market.
Spectra/Linde’s existing reputation and willingness to work with and understand the vision correction OEM’s specifications and quality needs is the sole reason for Spectra/Linde’s success in the vision correction market. For more information please contact our Excimer Laser Customer Service team.
