Jilin tianhua opto-electrical technology development co., ltd., production and sale of precise optical elements. Our company locates in changchun city, jilin province, the optical base of china. We specialize in cylindrical mirror. There are more than 60 people in the company, who are researchers and professional technicians of changchun institute of optics, fine mechanics and physics, chinese academy of sciences. Our company has advanced optical cold-working detecting equipments and process equipments, and provides high-quality products and professional services for customers. We can produce cylindrical mirrors of different specifications, sizes, radii, materials and special shapes or organized types. We can process high-precision cylindrical mirrors of special optical characters, such as: achromatic cylindrical mirror, parabolic mirror, cylindrical ellipsoidal mirror and hyperbolic mirror. Cylindrical mirrors of complicated shapes, such as: fan-typed, off-axis cylindrical mirror, angular cylindrical mirror, etc. In addition, we produce other optical elements such as flat mirror, window, prism, spherical lens, etc. Our company can design and process all kinds of optical elements according to requirements, and do gluing and filming on products. Substrate materials we usually use are optical glass, bk7, k9, violet quartz, ultrared quartz, caf2 crystal zf soft material, etc. (special material should be supplied by customers) the company takes “be faithful and honest, keep quality first, supply products on time and pursue perfect” as its operational principle. We are glad to communicate and cooperate widely with friends in domestic and abroad. We promise: to become your “wholesaler” of optical elements with high quality, high speed and low price.

Cylindrical lenses Our company was founded in 2000 as an optics scientific development, named xin xing liang electric- optics of jilin province, co., ltd. It has evolved into a unique company, specializing in the manufacture of cylindrical lens etc.
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
