Optical glass rod lens for endoscope lens
Endoscopes have a series of high-resolution optical glass rod lenses. The endoscopes can be forward viewing (0 degrees) or angled (10–120 degrees) to allow visualization out of the axis of the telescope and increase the FOV by rotating the instrument. Under the condition of high refractive index, some optical components can achieve short focal length. Therefore, the micro lens becomes an ideal choice in the field of hig
Lenses are classified by the curvature of the two optical surfaces. A lens is biconvex if both surfaces are convex. If both surfaces have the same radius of curvature, the lens is equiconvex. If one of the surfaces is flat, and the other one of the surface is convex, the lens is plano-convex lens. The plano convex lens is the most common type of lens element. It can be used to focus, collect, and collimate light. A plano convex lens is useful as a simple imaging lens for systems where ima
Ruby material is grown in the factory by melting ultra-pure Al2O3 at temperatures above 2000 deg. degrees Celsius to create a single crystal. This hard material can be polished to a very good surface finish. We offer sapphire and ruby balls in a variety of sizes down to 0.15 mm in diameter. Typical applications: fiber optic connectors, flow meters, rotameter, barcode readers, gemstone bearings. low friction number, high hardness, corrosion resistance, low coeffi
The Fresnel lens reduces the amount of material required compared to a conventional lens by dividing the lens into a set of concentric annular sections. An ideal Fresnel lens would have an infinite number of sections. In each section, the overall thickness is decreased compared to an equivalent simple lens. This effectively divides the continuous surface of a standard lens into a set of surfaces of the same curvature, with stepwise discontinuities between them.
Sapphire (molecular formula Al2O3) single crystal is an excellent multifunctional material. It is resistant to high temperature, good thermal conductivity, high hardness, infrared transmission and good chemical stability. It is widely used in many fields of industry, national defense and scientific research (such as high temperature resistant infrared windows, etc.). It is also a widely used single crystal substrate material and is the preferred substrate for the current blue, violet and white light emitting diode (LED) and blue laser (LD) industries (need t
How Fresnel Lens works in the Projector
Fresnel lens used in the projection system, its role is to collimate light and focus light. Fresnel lens will
A cylindrical lens is a lens which focuses light into a line instead of a point, as a spherical lens would. The curved face or faces of a cylindrical lens are sections of a cylinder, and focus the image passing through it into a line parallel to the intersection of the surface of the lens and a plane tangent to it. The lens compresses the image in the direction perpendicular to this line, and leaves it unaltered in the direction parallel to it (in the tangent plane).
What is EORI? EORI is the abbreviation of "Economic Operators Registration and Identification". The EORI number is the "European Union Economic Registration and Identification Number". It is a unique number in the entire European Union and is issued to import and export companies or personnel by the customs of EU member states. What is the EORI number used for? The EORI system was introduced o
The difference of Fused Silica glass JGS1,JGS2, JGS3
The optical fused silica glass windows produced by our factory can withstand high temperature and high pressure, and are mainly used in special light sources, optical instruments, optoelectronics, military industry, metallurgy, semiconductors, optical communications and other fields. It can test temperature: 1200 degrees, softening temperature: 1730 degrees, the specific parameters are as follows. 1. JGS1 (Far Ultraviolet Optical Quartz Glass) It is optical quartz glass melted
Sapphire Wafer/ Sapphire Substrate
Sapphire belongs to the corundum group of minerals. It is a common coordination oxide crystal. It belongs to the trigonal crystal system. The crystal space group is R3c. The main chemical composition is AI2O3. The material has a mode hardness of up to 9, second only to diamond. Sapphire has good chemical stability, low preparation cost and mature technology, so it has become the main substrate material of GaN-based optoelectronic devices. In addition, it has good dielectric and mechanical properties, and is widely used in flat panel displays, high-efficiency
The application of convex lens in life
The convex lens is made according to the principle of light refraction. It has a unique shape. The thickness of the middle part is much thicker than that of the edge part. Compared with the concave lens, it is not only the opposite in appearance, but also has two focal lengths at one focal length. It can distinguish between the real and the real in the room, the size of the object can be distinguished at the double focal length, and it also has the characteristic of concentrating light.
Performance and use of concave grating spectrometer
Generally speaking, a concave grating spectrometer is a kind of diffraction grating. It is used in a specific environment, so it also has special parameter performance, including five points as follows: 1. The concave grating spectrometer is operated and analyzed by Ocean Optics' Spectrasuite spectrum operating software, and can be used on Windows, Macintosh, and Linux operating platforms. It is also compatible with Ocean Optics' OmniDriver and SeaBreeze software development platform.
Realpoo Optics broke through the technical difficulties and manufactured the N-SF11 larg ball lens with a diameter of 100mm.
Sapphire bearings / Rubby bearings
In the instrumentation industry, sapphire/ruby bearings are widely used due to their simple structure, low manufacturing cost and long service life. In recent years, with its high-speed development, it has gradually been widely used in ultra-high-speed rotating machinery.
