Product Description
Bi-concave glass lenses are manufactured with both surfaces concave. These lenses have negative focal lengths. These lenses diverge collimated incident light and form virtual images, which are seen through the lens. They are often used to expand light or increase focal lengths in existing systems. They are used in laser beam expanders, optical character readers, viewers, and projection systems. Antireflection coatings can be ordered as an option.
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 lenses.
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.
