Custom Optical Sapphire Windows Glass Lens Watch Crystal Glass 19E1M42
Sapphire’s excellent physical and optical performance has been widely use on some luxury watch as cover, military and aerospace field, such as wave-transmitting window, laser window, guard plate, pressure sensor, gyroscope, durable bearing, optoelectronic tracker, IR security system, optronic masts etc. The main properties of sapphire: 1) Sapphire has excellent light guides, and its transmittance in the range of 150-7500 nm, covering the ultraviolet, visible, near infrared, mid-infrared wave band, etc. 2) Its expansion coefficient of only 5 * 10-6 /degree, the melting point is 2050 degrees, operating temperature up to 1900 degrees, with excellent resistance to thermal shock and high temperature performance. 3) Excellent mechanical properties, hardness upto Mok’s 9, but also has good compressive strength and flexural strength. 4) It has a good sealability to maintain the vacuum sealing system, even if generated by thermal shock no any leakage causes. 5. Sapphire is a great choice of material of radioresistance and electric insulativity. Sapphire Windows made by VY Optics are considered among the best in the industry. Our custom optical components are excellent at protecting delicate lasers, sensors, cameras, and other devices due to their superior strength and scratch resistance. Sapphire windows can also be used as viewports in high pressure or vacuum situations. Sapphire pressure windows can be made much thinner than their optical glass counterparts due to sapphire’s high modulus of ruptur Material: Sapphire, ZnSe, ZnS, Ge, Si, LT, LN etc.. Dimension: 1.0mm-460mm Thickness: 0.1mm-30mm Surface Accuracy: lambda/20 Surface Quality: 10-5 Tolerance: +/-0.01mm Parallelism: 30″
