All set to debate your quartz plate specifications? Our specialized crew is standing by to offer qualified guidance, customized answers, and competitive prices.
This is often vital for precision devices and high-temperature products that involve precise dimensional Regulate, ensuring balance and dependability less than fluctuating temperatures.
Note: One-crystal or crystalline quartz in general is not inside our producing array. We only course of action amorphous glass elements.
Ohara artificial fused silica is produced applying axial vapor stage deposition to create remarkably pure optical-quality silica with fantastic thermal steadiness and transmission Attributes.
Valley Style and design understands the necessity of precision in microelectronic equipment substrates. Inside our nearly fifty years of encounter, we’ve delivered a large number of important semiconductor materials for electronics, and we’re pleased to incorporate 450-mm silicon wafers.
The scale of Sapphire that may be polished is proscribed only by the material availability. Sapphire blanks as many as 12″ diameter might be lapped, optically polished, diced and CNC machined. Keeping precise tolerances together with flatness, and parallelism is crucial For numerous applications.
Our solutions meet RoHS specifications, confirming they’re absolutely free from limited hazardous substances and environmentally accountable.
Fused silica glass handles continuous functioning temperatures as many as one thousand °C and tolerates sharp thermal gradients without having problem. Its coefficient of thermal enlargement is extremely fused silica quartz plate for optical windows and semiconductor use minimal, which allows for dimensional security beneath thermal load that is a prerequisite for laser optics, semiconductor processing equipment, and any software the place mechanical precision cannot be compromised by warmth.
Fused Silica will not be the same as Fused Quartz Besides the optical grades described on this site, we also provide a a lot less advanced quartz glass form referred to as pure quartz glass or fused quartz. Although the names are related, the products are really unique. Fused quartz consists of appreciably more impurities than synthetic fused silica since it is created by melting naturally happening quartz crystals from silica sand.
The absence of metallic impurities as well as other UV-absorbing contaminants is what sets optical quartz glass apart. Transmission at 185 nm fused silica quartz plate for optical windows and semiconductor use exceeds 80% – a general performance that the majority glasses are not able to solution.
All TOQUARTZ® quartz plates adjust to EU Achieve laws, ensuring they’re free from harmful substances and Harmless for world wide distribution.
Creating on our practically fifty several years of expertise in processing a number of supplies to extremely slim thicknesses, Valley Layout has leveraged this information to drive new restrictions in extremely skinny processing, sprucing some elements to as skinny as 10 microns.
Quartz glass plates show extremely substantial transparency, significantly throughout the ultraviolet to infrared spectral selection. This will make them invaluable in optical programs, like the fabrication of lenses, optical fibers, and optical windows.
With a fracture modulus exceeding 350MPa, our quartz plates supply remarkable longevity and mechanical integrity. Their low friction fused silica quartz plate for optical windows and semiconductor use coefficient guarantees extended provider lifetime in superior-flow applications and demanding mechanical environments.
