Micro Spherical Lenses 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 high precision applications. Through years of accumulated processing know-how technologies and production capacity, high standard thin film coating performance and strict testing requirements, Photonchina provides customers with one of the world's smallest but excellent micro lenses products, which have been widely used in various medical devices (endoscope lens, for example), precision surveying and optical communications instruments. From design, manufacturing to optical coating, from endoscope lens, capsule lens to special-required rod lens, from single mini lens to glued lenses system, engineers in Photonchina implement strict production process to ensure stable quality, competitive price as well as responsive lead time. A variety of optical glass or other materials, such as BK7, N-SF11, H-LAF76, Fused Silica and so on are available for customers design. H-LaF53, for instance, has often been used in endoscope lens or capsule lens production. We have a wide range of lenses in shape: convex, concave, biconvex, meniscus etc. Material : N-SF11H-LaF53H-LaF76 Fused Silicon etc. Radius of Curvaturemm R0.25R Diametermm 0.5 5 Tolerancemm 0.005 0.05 Lengthmm L0.5 L30 Tolerancemm 0.020.06 Thickness tolerancemm 0.01 0.1 Surface Quality 10/580/50 Flaness /20/4 Off centering 110 Optical coating : Upon request
Carrot : Carrot is a kind of radish, as,cruciferous carrot, also known as,big carrot, northeast carrot one or two year old herbs, root meat, spherical, root bark red, root meat white. Originated in China, all around cultivation, the Northeast is the main producing areas of large carrots, due to climate and variety factors such as the formation of its high nutritional value and medicinal value. Carrot micro-temperature, into the lungs, stomach two, with heat, detoxification, dampness, stasis, stomach digestion, Huatanzhike, Shun gas, convenience, Shengjinzhike, fill in the five internal organs and other functions. A wide variety of radishes, raw to spicy less as well.
Photonchina produces the smallest rod lenses for customers at home and abroad. Micro rod lenses: 0.5-1.8mm diameter, 1.0-25mm length, with one end of designated curvature radius and another end of arbitrary angle. Both ends of arbitrary radii or angle are also available. Highly customized products for a wide range of applications from medical device, fiber communications, optical display and surveying equipment. What is more, we can provide unique rod-shaped glued lenses by combining special gluing/cementing technics and edging skill. These glued/cemented rod lenses subassembly can be made of up to four single micro rod lenses with various combination. Rod lens assembly systems are able to provide images with greater brightness, contrast and color reproduction than conventional lenses. Rigid endoscope, for instance, which usually has a series of high-resolution optical glass rod lenses, can be forward viewing (0 degrees) or angled (10120 degrees) to allow visualization out of the axis of the telescope and increase the FOV by rotating the instrument. The optical quality of lens-generated images of rigid endoscopes still surpasses that of the fiber-optic or digital images produced by flexible scopes. High performance optical coatings for rod lenses are provided. Optical glass material NBK7, N-SF11 from Schott, Corning 7980 etc, are all available.

Micro Silica Sand: Micro silica also known as fume, is an amorphous (non-crystalline) polymorph of silicon dioxide, silica. It is an ultrafine powder collected as a by-product of the silicon and ferrosilicon alloy production and consists of spherical particles with an average particle diameter of 150 mm. The main field of application is as pozzolanic for high performance concrete because of its extreme fineness and high silica. Applications : Silica is added to Portland cement concrete to improve its properties, in particular its compressive strength, bond strength, and abrasion resistance. These improvements stem from both the mechanical improvements resulting from addition of a very fine powder to the cement paste mix as well as from the pozzolanic reactions between the silica fume and free calcium hydroxide in the paste. Advantages : Addition of silica also reduces the permeability of concrete to chloride ions, which protects the reinforcing steel of concrete from corrosion, especially in chloride-rich environments such as coastal regions and those of humid continental roadways and runways (because of the use of deicing salts) and saltwater bridges.
