- Excimer Info
An excimer laser 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
Since the 1970’s, lasers have been used in ophthalmology for conditions such as glaucoma and retinal tears. However, the use of LASIK for vision was not FDA approved in the United States until the late 1990’s. Since then, LASIK surgery has gained immense popularity with people seeking alternatives to glasses and contacts. Now, according to the FDA, over 600,000 LASIK surgeries are performed in the United States each year.
Spectra/Linde has been involved in the vision correction market since the beginning. In fact, their hard work with industrial Excimer OEM’s paved the way for their entrance into the vision correction market. Spectra/Linde’s existing reputation and willingness to work with vision correction OEM’s to understand their specifications and quality needs has led to great success.
