How does Sapphire Domes Differ from Ordinary Glass?

图片
As a  Sapphire Optical Components China , share with you. (1) Laboratory method: The detection of  Sapphire Domes  is very similar to the identification of jewelry, and the same equipment is used. The more commonly used instrument for jewelry identification is the refractometer, which can determine the refractive index of the object being tested. Although sapphire glass is artificial, But its refractive index is the same as natural, both 1.76 ~ 1.77, because sapphire glass is crystalline, so it has a heavy refractive index like crystal, which is 0.008. During the inspection, rotate and observe the polarizer on the eyepiece. It can be seen very clearly. The flat glass is better to observe, the spherical surface is not very good, and the refractive oil needs to be applied when testing. The refractive index of mineral glass is about 1.52, it is easy to distinguish it from sapphire, and it There is also no refraction. Sapphire Windows Another method is to use a polarizer. Any cr

How to Clean Optical Lenses After Coating?

As an  Optical Lenses Manufacturers , share with you how to clean the optical glass coating. The cleaning method: Cleaning method one: Ultrasonic cleaning 1. Dilution ratio: 5% of cleaning agent. If the degree of cleaning pollution is serious, increase the solution concentration. 2. Cleaning equipment: ultrasonic cleaning machine cleaning. 3. Cleaning process: Pour the prepared cleaning agent into the ultrasonic cleaning machine, and then put it into the  Optical Lenses  for cleaning. After removing the cleaning material from the solution, rinse it immediately and thoroughly. Do not leave the cleaning material for too long and rinse it. Rinse three times to ensure complete removal of contaminants and residual traces of the cleaning solution. Dry the items carefully after cleaning, and use a lint-free cloth or hot air to dry them. 4. Cleaning time: The cleaning time is 2-5 minutes, depending on the degree of contamination, the cleaning time can be extended. 5. Cleaning te

Properties of optical components made of calcium fluoride

Calcium fluoride is commonly used for optical components in the spectral range from ultraviolet to infrared. CLZ Pr ecision  Opti cs  Co., Ltd can offer you  optical lenses ,  optical windows , optical domes,  optical prisms , optical mirrors and other optical components made of calcium fluoride. The transmission of  calcium fluoride  covers the wavelength range from 130 nm in vacuum UV to 9 μm in the far infrared. Calcium fluoride is also used in high- powered  laser optics due to its good transmission (approx. 94%). In general, the polished surface of calcium fluoride is very stable and can be used for many years. In addition, the lower refractive index of calcium fluoride enables it to be used directly without an antireflectiv e  coating. Calcium fluoride has a high mechanical stability. Calcium fluoride is ideal for applications that require low damage thresholds, low fluorescence and high uniformity. It is commonly used in excimer lasers, spectrometers and cooled thermal

How to improve the CO2 laser damage resistance of Fused Silica Precision Lenses?

Fused Silica is an amorphous state of silicon oxide. It is a typical glass. Its atomic structure is long-range disordered. It provides its high use temperature and low thermal expansion coefficient through three-dimensional cross-linking. As a  Fused Silica Precision Lenses Supplier , share with you. Improving the laser damage resistance of  Fused Silica Precision Lenses  are the main element that guarantees the load capacity of high-power solid-state laser devices. However, laser-induced damage on the surface of optical components is still a big "bottleneck". UV Grade Fused Silica Lenses (1) By studying the characteristics and types of scratches on the surface of fused silica, the final result is obtained: the optical elements can be divided into lateral, radial, Hertz cone and "smearing" scratches from the scratch form; from the formation, properties Can be divided into plastic, brittle and mixed scratches. The shape of the damage point is directly relate

Why is fused silica the crucial material in optical applications?

图片
Quartz glass, especially fused silica, is widely used in optical applications because of its unique properties . CLZ Precision Optics Co., Ltd can provide you with  optical lenses ,  optical windows ,  optical domes , optical prisms, optical mirrors and other optical components, which are made of quartz glass. Properties of fused silica High transmission from the ultraviolet to the infrared spectral range According to the spectral region, quartz glass is divided into  JGS1 ,  JGS2 ,  JGS3  (related to the Hydroxyl Group in the material). JGS1 is Fused Silica with UV-Quality. It has high transmittance in the 180-2500nm wave band (about 93.5%). JGS2 with a transmission rate of more than 93.5% is transparent in the 220-2500 nm band. JGS3 is Fused Silica with IR-Quality. It has high transmittance in the 260-3500nm wave band. High thermal resistance and softening temperature The thermal expansivity of fused silica is extremely low. It means fused silica withstands sever

Do you know about Sapphire Windows?

Sapphire crystal generally refers to artificial sapphire, which is very different from the jewels that people usually understand-natural sapphire. It is generally used in the manufacture of watch mirrors. Sapphire Windows  is a wear-resistant material with tungsten-titanium alloys and high-tech ceramics. Although these materials are resistant to abrasion, they cannot withstand strong impacts. At the same time, some materials with the same or higher hardness (such as abrasive stones, sandpaper, nail polish, granite surfaces, concrete walls and floors, etc.) may Scratch the surface of these materials. Sapphire Windows Sapphire is the general name for corundum gemstones other than red rubies among corundum gemstones. The main component is Al2O3. Sapphire glass refers to synthetic sapphire. Gem-grade sapphire can be easily and cheaply produced in the laboratory. Its chemical composition and physical properties are the same as a natural sapphire. Sapphire Domes , similar to corun
