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.

Acrylic lenses, whose base plate material is PMMA, also known as pressure afterburner lenses, sub-afterburner lenses, in fact, refers to the general term of PMMA sheet after electroplating, using plastic lenses instead of glass lenses, has the advantages of light weight, not easy to break, easy shaping and processing, easy coloring, etc., the momentum of development is increasing, and has become a kind of technology in lens production. Plastic sheets can generally be made into: single-sided mirror, double-sided mirror, taped mirror, paper mirror, semi-lens, etc. can be done according to different requirements. For example, mobile phones and TV screens are visible everyday. Because acrylic is difficult to produce and its cost is high, there are many substitutes of high quality and low price in the market. These substitutes, also known as acrylic, are actually ordinary organic or composite boards (also known as sandwich boards). Ordinary organic board is cast with ordinary organic glass cracking material and pigment. Its surface hardness is low, and it is easy to fade. After polishing with fine sand, the polishing effect is poor. The composite board has only a very thin acrylic surface and ABS plastics in the middle. It is easy to delaminate due to thermal expansion and contraction in use. The true and false acrylic can be identified from the slight chromatic aberration and polishing effect of the plate section. 1.
