Model Description

■ Features It is an ultra -high -purity artificial crystal manufactured by using high -purity raw materials, optimizing the development conditions and thorough quality control. The impurities concentration, linear defective density, and incration density in crystals are extremely small, and it is a top -class ultra -high pure product in all items in the artificial crystal and quality standard "JIS C 6704". The extremely high purity allows you to bring out the original characteristics of the crystal to the extreme. The effect of maintaining high -resistance and high transmittance for high -output and short -wave length lasers, less defective effects for radiation irradiation, excellent characteristics for optical parts in space, radiation environment, and high -stabilizer. Can be expected. The impurities content is extremely low compared to the standard products. The absorption of 3585cm-1, which indicates the containing a typical impurities of the crystal, is rarely compared to the standard products. ■ Remarks 1. Indicates the maximum size of the block. It can be delivered by processing to a predetermined size and thickness. Please specify. 2. Inclusion density is based on JIS-C 6704. The IA grade is the most inclusive product for optical applications. 3. The infrared absorption coefficient α value is based on JIS-C 6704. It is standardized by the absorption coefficient by hydroxyl group -OH. 4. This is an example of a quantimal analysis by ICP-MS. It does not guarantee the impurities. At the request, it is possible to perform an analysis for each rough stone and attach it, but in that case, the analysis cost will be charged separately. 5. The artificial crystal has a phase transition temperature at 573 ° C. Please use it at the temperature below this. ■ High transmittance characteristics N-Grade EX maintains a high permeability to the vivid ultraviolet area near the absorption end. ■ High laser durability High resistance to long -term irradiation of 193nm ARF Exima laser. There is little deterioration of transmittance before and after irradiation. ■ Radiation resistance Even if the absorption dose of the gamma wire is increased, the energy absorption due to radiation defect is low. It is expected that excellent characteristics will be obtained in the space environment. * Please try the vibrator, camera, and equipment window material used in space environment and radiation environment.
