Product Description CaF2 Lens Window IR Grade Calcium Fluoride Custom Optical WindowsProduct DescriptionThe exceptionally high laser durability of CaF2 makes it the material of first choice for litho excimer laser optics, beam deliveries, and all excimer laser wavelengths in a wide range of other applications.Synthetic calcium fluoride crystals extend the application range of optical materials from the vacuum ultraviolet (VUV) to the infrared (IR) region. They offer very good transmission performance, ranging from 130 nm to 9 μm. Advantages in optical performance can be realized with calcium fluoride in chromatically corrected optical systems, photography, HDTV zoom lenses, as well as in microscopy. Further applications encompass sensors (especially in the IR spectrum), spectrometers, and medical lasers. Calcium fluoride single crystals, grown from high purity raw materials, are required for illumination and projection optics in 248nm and 193nm micro-thography technologies. Hellma Materials' expertise & Raytek Optics allow fabrication of CaF2 blanks in diameters up to 440mm and with a thickness exceeding 100mm and highest transmission down to 157nm.The very high laser durability of CaF2 makes it the first choice material for lithoexcimer laser optics, beam deliveries, and for all excimer wavelengths in a wide range of other applications.Synthetic calcium fluoride crystals complete the application range of optical materials from VUV to IR with a very good transmission ranging from 130nm to9μm. Advantages in optical performance can be achieved with calcium fluoride in chromatically corrected optical systems in astronomy photography, HDTV zoom lenses, as well as in microscopy. Further applications are sensors [especially in IR spectrum], spectrometers and medical lasersHellma Materials and Raytek Optics offer CaF2 components and blanks with different crystals along with different surface qualities.CaF2 is the ideal choice for VUV/DUV/UV,VIS AND IR applications.Key quality features of these crystals include excellent UV transmittance, which allows them to effectively transmit ultraviolet light; high laser durability, making them resistant to damage from laser irradiation; low stress birefringence, ensuring minimal optical distortion due to stress; and high refractive index homogeneity, which is vital for consistent optical performance.Products Name: Calcium fluoride single crystals Alias: Calcium fluoride single crystals, Calcium fluoride, CaF2, Lithotec Calcium Fluoride, Calcium Fluoride IR Materials, CaF2 IR materials, CaF2, Hellma CaF2, Hellma CaF2, CaF2 crystals, CaF2 crystals, UV CaF2, CaF2 UV materials, etc.Main Characteristics:1).Excellent UV Transmittance2).High laser durability3).Low stress birefringence4).High refractive index homogeneity5). Calcium fluoride features a very low spectral dispersion, a low non-linear refractive index and is available in sizes up to 440 mm diameter.
