Focusing or imaging applications
Focal Length: F = -R/(n-1)
N: Refractive index
R: Radius curvature

Plano-concave lenses are useful for a wide range of applications. These lenses are manufactured from BK7A grade A (or customer design) optical glass and are supplied uncoated. Anti-reflection coatings are available as listed earlier in this section. To order an anti-reflection coated lens simply append the wavelength in nanometers to the product number.

Jilin Henghua Optoelectric Co, Ltd. is a professional large-scale manufacturer of optical products, integrating development and production together. We are specialized in manufacturing all types of optical products and related products. Our main products include lens, cylindrical lens, prism, window, rod, etc. Our technical assistance engineers have worked for the Light machine research institute for 30 years as the associate research fellow and research fellow . Located near Beijing, we enjoy convenient air, land and water transportations.

We imported main production equipment and test equipment. Curve generator/CG-2.0 milling & grinding machine, SPCM-MI centering & edging machine, precision polishing machine and other advanced equipment facilitated on the production lines make the traditional optical cold working process simple, efficient, precise and reliable. We can provide relevant inspection reporter for our products.

Our company has introduced South Korea NVC-G110 electronic beam evaporation vacuum coating machine and Japan SHIMAZU 3600UV spectrophotometer for the R&D and production of a variety of optical thin film products, in which single wavelength antireflective film, broadband antireflective film, partial reflection film, interference filter, color filter and other series of products are available for users. High quality optical films have passed technical appraisement.

Currently, we have already exported our products to the USA, Germany, Canada, South Korea, Japan and other countries. Our company will always take the concept of "Constant improvement, constant progress" and the tenet of "Quality first, credit first" to supply high quality products to customers.
