High Temperature Quartz Tube
How strong is quartz glass? Properties of Fused Silica/Quartz Glass Property Value General Density 2.23 Mechanical Design Tensile Strength 48 Design Compressive strength 1100 Young’s Modulus 72 What is quartz glass used for? Major applications of quartz glass products include both the lighting and the semiconductor industry. In the lighting products, quartz glass is widely used in high-temperature arc and filament lamps requiring high purity to minimize devitrification and provide optimum sag resistance. What temp does quartz glass melt? approximately 1600 °C, quartz melts at approximately 1600 °C forming a tacky liquid. In the course of melting, many silicon-oxygen bonds are broken. Can quartz be used to make glass? Quartz sand is used in the production of container glass, flat plate glass, specialty glass, and fiberglass. Is glass harder than…
How to choose laser safety glasses?
Buyers Guide | How to Choose Your Laser Safety Glasses? Published by The VY Optoelectronics Co.,Ltd. | Laser Safety Glassses on November 23rd. Typically, to determine what type of Laser Safety glasses or goggles to buy, the following is needed: 1) Know your laser’s wavelength. 2) Determine the protection level needed based on your laser’s output parameters, or look for the recommended Optical Density (OD). This can ask your engieer, or please feel free to contact us for a assitance. 3) Select a filter whose specifications match the above information. Laser safety glasses is very necessary for a laser power even 5mw, they are extensively used in the field of laser alignment, laser medical treatment, Laser industry etc. Lasers are more dangerous than most people understand, and your eyes are the most vulnerable to…
Sapphire Window
Sapphire Window Flat is a high-performance optical component made from single-crystal sapphire (Aluminum Oxide, Al₂O₃). Sapphire is renowned for its exceptional physical and optical properties, making it widely used in various high-tech applications, especially where high strength, stability, and broad spectral transparency are required. Key Features and Applications of Sapphire Window Flats Optical Performance: Wide Transparency Range: Sapphire offers a broad transparency spectrum, ranging from ultraviolet (UV) to near-infrared (NIR), with a transmission range of approximately 0.2 to 5.5 micrometers. High Refractive Index: Sapphire has a high refractive index, which can lead to some reflection even without coating. However, anti-reflective coatings can significantly reduce reflectance. Minimal Optical Anisotropy: Sapphire maintains excellent optical performance even at large angles of incidence, thanks to its minimal optical anisotropy. Physical Properties: Exceptional Hardness: Sapphire…

Get a perfect look inside with a hole inspection lens
VY Optoelectronics Co.,Ltd. produce and design kinds of optical lenses, such as infrared lens, imaging lens, industrial lens etc..One of the hottest selling industrial lenses is HOLE INSPECTION LENS, we aim to disign a 360 degrees hole inspection lens which can image at both the inner walls and the bottom of the objects, the shape of the objects can be very different, such as threaded holes, cones, bottle caps, cylinders and so on.
Introduction to the Traditional Polishing Process of Optical Lenses
After the optical lens is finely floored through the abrasive liquid, there is nonetheless a crack layer about 2–3m thick on the surface. The approach to do away with this crack layer is polishing. The mechanism of sprucing is identical to that of grinding, besides that the device cloth used is distinct from the sprucing liquid. The substances used for sharpening are flannel, sharpening leather-based, and asphalt. Usually, a high-precision sharpening floor is required. The most often used fabric is high-grade sprucing asphalt. The use of asphalt for sprucing is to pressure the sharpening liquid to grind the floor of the lens to generate warmth via the exceptional floor of the asphalt, so that the glass melts and flows, melts away the difficult vertices and fills in the valley backside…
