Propery of Zinc Sulfide   Broadband Transmission Wavelength ZnS Material including CVD ZnS and Multispectral ZnS, CVD ZnS transmission range from 3-5um and 10-14um, Average of Transmittance 50%, Multispectral ZnS Average transmission 70% in the wavelength 0.37-12um. High Refractive index and high Purity ZnS is a high index material 2.65, it’s suitable for optical components, high purity can reduce the light scatter and loss, improve the transmission efficiency and image quality of optical system. Resists radiation ZnS has a property of resist radiation damage from high energy light, extend the service life of optical components. Thermal and chemical stability High temperature conditions in high power laser systems to ensure the stability and reliability of the optical system. Processing Range 1.     commonly manufacture shape: windows, dome, prism, wedged, oval, step, drilling and special custom 2.     Size:5mm to 400mm 3.     Precison of processing 1)     Surface accuracy:RMS 1/50 to 1/100 2)     S/D:40/20(Standard), High precision 20/10 3)     Roughness:<0.05um

A spherical lens is a spherical lens, which is commonly used in scene such as fiber couplers, endoscopes or bar code scanners. For spherical lenses, it has two focal length concepts, one is the conventional focal length EFL, and the other is the back focal length BFL BFL = EFL - D / 2 EFL = n * D / [4 * (n - 1)]  n stands for Refractive index of material,For example, water is 1.33, crystal is 1.55, diamond is 2.42, heavy flint glass is 1.65, and K9 glass is 1.5163. Material:H-K9L,Sapphire, Ruby, JGS1 JGS2 JGS3 ,Single-crystal Silicon,Aluminum oxide,TAFD40, ZnS etc optical glass accordingly customers design Types:Ball Lens, Half Ball Lens Diameter Tolerance:+/-0.005mm Sphericity:+/-0.001mm Surface Accuracy:lambda/4@632.8nm Surface Quality:40/20 Coating:upon customers demand   In addition to refractive index, the main reference for optical glass classification is Abbe number. The Abbe number is a physical quantity invented by German physicist Ernst Abbe, also known as the "dispersion coefficient", to measure the degree of light dispersion in transparent media.   Generally speaking, the larger the refractive index of the medium, the more serious the dispersion and the smaller the Abbe number; Conversely, the smaller the refractive index of the medium, the slighter the dispersion, and the larger the Abbe number.   Domestic e-commerce platforms have a large number of "glass balls" or even "crystal balls" on sale, their size is rich, the price is low, even the nominal price of high-precision glass balls, are also thousands of pieces.If you search for "optical glass ball" or "optical ball lens", then the price will be much more expensive. This is because both materials and processing technology, there are huge differences. General ordinary glass balls may be batch hot casting or hot melt circular processing, there may be a large number of bubbles and impurities inside the material, and the ellipsoid of the molding is not too high.   However, optical glass materials are mostly crystals and cannot be hot melted. Optical ball lenses of this kind, generally can only be cold processing grinding. Moreover, in the early stage, there will be certain requirements for the type of material, the purity and uniformity of the material, and the surface finish, ellipsoid and profile accuracy in the later stage.   So, naturally, the overall cost will be high.   Ordinary choice of ball lens requirements are not high can choose H-K9L, a wide variety of sizes, Large inventory selection. A better option is a high-index spherical lens, which has better optical properties and a higher price.   In a word, CCRQ have many stock size ball lens and half ball lens for samples testing,

Optical window is the basic optical elements in optical systems, in order to separate the inner and outside and isolated each other and then make a protection of inner components. There are many optical glasses for options such as K9, fused silica (JGS1, JGS2, JGS3), CaF2, Sapphire, MgF2, BaF2, Znse, ZnS, Silicon, Germanium upon customers demand. Fused Silica window CCRQ can supply JGS1, JGS2, JGS3, Corning 7979, 7980 etc. customized fused silica window and coating or not as choice Fused silica window has good temperature resistance characteristics, rapid high and low temperature, low spectral loss, UV IR wide spectral transmission, high precision and low expansion coefficient and so on, so it’s widely used on optical systems and equipment such as lasers, optical equipment, industrial, medical, lighting, semiconductor, communication, electronics, optical fiber etc JGS1 JGS2 JGS3 transmission curve JGS1 has a good transmission band from 185-2500nm, on the wavelength 185nm, transmission can reach 90%, it has granule’s structure JGS2 has good transmission band from 220-2500nm, it has striped and granular structure JGS3 has good transmission band from 260-3500nm, transmission can reach 85%, but it has stripped and granule’s structure So far, CCRQ make the biggest circular size fused silica window/JGS1 Window is Diameter 420mm, thickness 5mm plane window, surface quality 40/20, we have been sent to serval batches and make good feedback from Europe customers. To be honest, such big size polishing process really have difficulties, we only handmade one by one to ensure the surface quality and flatness, accordingly customers demand we also make two surfaces AR coating on 1070nm, in the first order, we have a problem on the cracking and coating burst after done, for now we find the correct way to avoid these problems, we also have good material factory cooperations with better quality and best delivery time.
